This allows the user + to boot from a disk drive other than the so-called primary + master. This is especially convenient for some users who have + found that the simplest and cheapest way to keep a system backup is to + buy an identical second hard drive, and perform routine copies of the + first drive to the second drive using Ghost or XCOPY. Then, if the + first drive fails, or is attacked by a virus, or is scribbled upon by an + operating system defect, he can easily recover by instructing the BIOS + to logically swap the drives. It's like switching the cables on the + drives, but without having to open the case. + + More expensive systems with SCSI controllers often include BIOS + extensions which allow the SCSI drives to be re-ordered in a similar + fashion for up to seven drives. + + A user who is accustomed to taking advantage of these features may + become surprised when the results with FreeBSD are not as expected. + FreeBSD does not use the BIOS, and does not know the logical BIOS + drive mapping. This can lead to very perplexing situations, + especially when drives are physically identical in geometry, and have + also been made as data clones of one another. + + When using FreeBSD, always restore the BIOS to natural drive + numbering before installing FreeBSD, and then leave it that way. If you + need to switch drives around, then do so, but do it the hard way, and + open the case and move the jumpers and cables. + + + An illustration from the files of Bill and Fred's Exceptional + Adventures: + + Bill breaks-down an older WIntel box to make another FreeBSD box + for Fred. Bill installs a single SCSI drive as SCSI unit zero, and + installs FreeBSD on it. + + Fred begins using the system, but after several days notices that + the older SCSI drive is reporting numerous soft errors, and reports + this fact to Bill. + + After several more days, Bill decides it's time to address the + situation, so he grabs an identical SCSI drive from the disk drive + "archive" in the back room. An initial surface scan indicates that + this drive is functioning well, so Bill installs this drive as SCSI + unit four, and makes an image copy from drive zero to drive four. Now + that the new drive is installed and functioning nicely, Bill decides + that it's a good idea to start using it, so he uses features in the + SCSI BIOS to re-order the disk drives so that the system boots from + SCSI unit four. FreeBSD boots and runs just fine. + + Fred continues his work for several days, and soon Bill and Fred + decide that it's time for a new adventure -- time to upgrade to a + newer version of FreeBSD. Bill removes SCSI unit zero because it was + a bit flakey, and replaces it with another identical disk drive from + the "archive." Bill then installs the new version of FreeBSD onto the + new SCSI unit zero using Fred's magic internet FTP floppies. The + installation goes well. + + Fred uses the new version of FreeBSD for a few days, and certifies + that it is good enough for use in the engineering department...it's + time to copy all of his work from the old version. So Fred mounts + SCSI unit four (the latest copy of the older FreeBSD version). Fred + is dismayed to find that none of his precious work is present on SCSI + unit four. + + Where did the data go? + + When Bill made an image copy of the original SCSI unit zero onto + SCSI unit four, unit four became the "new clone," When Bill + re-ordered the SCSI BIOS so that he could boot from SCSI unit four, he + was only fooling himself. FreeBSD was still running on SCSI unit zero. + Making this kind of BIOS change will cause some or all of the Boot and + Loader code to be fetched from the selected BIOS drive, but when the + FreeBSD kernel drivers take-over, the BIOS drive numbering will be + ignored, and FreeBSD will transition back to normal drive numbering. + In the illustration at hand, the system continued to operate on the + original SCSI unit zero, and all of Fred's data was there, not on SCSI + unit four. The fact that the system appeared to be running on SCSI + unit four was simply an artifact of human expectations. + + We are delighted to mention that no data bytes were killed or + harmed in any way by our discovery of this phenomenon. The older SCSI + unit zero was retrieved from the bonepile, and all of Fred's work was + returned to him, (and now Bill knows that he can count as high as + zero). + + Although SCSI drives were used in this illustration, the concepts + apply equally to IDE drives. + + + Disk Naming Physical drives come in two main flavours, IDE, or SCSI; but there are also drives backed by RAID controllers, flash memory, and so forth. Since these behave quite differently, they have their own drivers and devices. Physical Disk Naming Conventions Drive type Drive device name IDE hard drives ad in 4.0-RELEASE, wd before 4.0-RELEASE.

Slices and Partitions Physical disks usually contain slices, unless they are dangerously dedicated. Slice numbers follow the device name, prefixed with an s: da0s1. Slices, dangerously dedicated physical drives, and other drives contain partitions, which represented as letters from a to h. b is reserved for swap partitions, and c is an unused partition the size of the entire slice or drive. This is explained in . Mounting and Unmounting Filesystems The filesystem is best visualized as a tree, rooted, as it were, at /. /dev, /usr, and the other directories in the root directory are branches, which may have their own branches, such as /usr/local, and so on. There are various reasons to house certain of these directories on separate filesystems. /var contains log, spool, and various types of temporary files, and as such, may get filled up. Filling up the root filesystem isn't a good idea, so splitting /var from / is often a good idea. Another common reason to contain certain directory trees on other filesystems is if they are to be housed on separate physical disks, or are separate virtual disks, such as Network File System mounts, or CDROM drives. The fstab File During the boot process, filesystems listed in /etc/fstab are automatically mounted (unless they are listed with ). The /etc/fstab file contains a list of lines of the following format: device /mount-point fstype options dumpfreq passno device is a device name (which should exist), as explained in the Disk naming conventions above. mount-point is a directory (which should exist), on which to mount the filesystem. fstype is the filesystem type to pass to &man.mount.8;. The default FreeBSD filesystem is ufs. options is either for read-write filesystems, or for read-only filesystems, followed by any other options that may be needed. A common option is for filesystems not normally mounted during the boot sequence. Other options in the &man.mount.8; manual page. dumpfreq is the number of days the filesystem should be dumped, and passno is the pass number during which the filesystem is mounted during the boot sequence. The mount Command The &man.mount.8; command is what is ultimately used to mount filesystems. In its most basic form, you use: &prompt.root; mount device mountpoint There are plenty of options, as mentioned in the &man.mount.8; manual page, but the most common are: mount options Mount all filesystems in /etc/fstab, as modified by , if given. Do everything but actually mount the filesystem. Force the mounting the filesystem. Mount the filesystem read-only. fstype Mount the given filesystem as the given filesystem type, or mount only filesystems of the given type, if given the option. ufs is the default filesystem type. Update mount options on the filesystem. Be verbose. Mount the filesystem read-write. The takes a comma-separated list of the options, including the following: nodev Do not interpret special devices on the filesystem. Useful security option. noexec Do not allow execution of binaries on this filesystem. Useful security option. nosuid Do not interpret setuid or setgid flags on the filesystem. Useful security option. The umount Command The umount command takes, as a parameter, one of a mountpoint, a device name, or the or option. All forms take to force unmounting, and for verbosity. and are used to unmount all mounted filesystems, possibly modified by the filesystem types listed after . , however, doesn't attempt to unmount the root filesystem. Adding Disks Originally contributed by &a.obrien; 26 April 1998 Lets say we want to add a new SCSI disk to a machine that currently only has a single drive. First turn off the computer and install the drive in the computer following the instructions of the computer, controller, and drive manufacturer. Due the wide variations of procedures to do this, the details are beyond the scope of this document. Login as user root. After you've installed the drive, inspect /var/run/dmesg.boot to ensure the new disk was found. Continuing with our example, the newly added drive will be da1 and we want to mount it on /1. (if you are adding an IDE drive substitute wd for da) Because FreeBSD runs on IBM-PC compatible computers, it must take into account the PC BIOS partitions. These are different from the traditional BSD partitions. A PC disk has up to four BIOS partition entries. If the disk is going to be truly dedicated to FreeBSD, you can use the dedicated mode. Otherwise, FreeBSD will have to live with in one of the PC BIOS partitions. FreeBSD calls the PC BIOS partitions, slices so as not to confuse them with traditional BSD partitions. You may also use slices on a disk that is dedicated to FreeBSD, but used in a computer that also has another operating system installed. This is to not confuse the fdisk utility of the other operating system. In the slice case the drive will be added as /dev/da1s1e. This is read as: SCSI disk, unit number 1 (second SCSI disk), slice 1 (PC BIOS partition 1), and e BSD partition. In the dedicated case, the drive will be added simply as /dev/da1e. Using sysinstall You may use /stand/sysinstall to partition and label a new disk using its easy to use menus. Either login as user root or use the su command. Run /stand/sysinstall and enter the Configure menu. With in the FreeBSD Configuration Menu, scroll down and select the Partition item. Next you should be presented with a list of hard drives installed in your system. If you do not see da1 listed, you need to recheck your physical installation and dmesg output in the file /var/run/dmesg.boot. Select da1 to enter the FDISK Partition Editor. Choose A to use the entire disk for FreeBSD. When asked if you want to remain cooperative with any future possible operating systems, answer YES. Write the changes to the disk using W. Now exit the FDISK editor using q. Next you will be asked about the Master Boot Record. Since you are adding a disk to an already running system, choose None. Next enter the Disk Label Editor. This is where you will create the traditional BSD partitions. A disk can have up to eight partitions, labeled a-h. A few of the partition labels have special uses. The a partition is used for the root partition (/). Thus only your system disk (e.g, the disk you boot from) should have an a partition. The b partition is used for swap partitions, and you may have many disks with swap partitions. The c partition addresses the entire disk in dedicated mode, or the entire FreeBSD slice in slice mode. The other partitions are for general use. Sysinstall's Label editor favors the e partition for non-root, non-swap partitions. With in the Label editor, create a single file system using C. When prompted if this will be a FS (file system) or swap, choose FS and give a mount point (e.g, /mnt). When adding a disk in post-install mode, Sysinstall will not create entries in /etc/fstab for you, so the mount point you specify isn't important. You are now ready to write the new label to the disk and create a file system on it. Do this by hitting W. Ignore any errors from Sysinstall that it could not mount the new partition. Exit the Label Editor and Sysinstall completely. The last step is to edit /etc/fstab to add an entry for your new disk. Using Command Line Utilities * Using Slices Dedicated If you will not be sharing the new drive with another operating system, you may use the dedicated mode. Remember this mode can confuse Microsoft operating systems; however, no damage will be done by them. IBM's OS/2 however, will “appropriate” any partition it finds which it doesn't understand. &prompt.root; dd if=/dev/zero of=/dev/rda1 bs=1k count=1 &prompt.root; disklabel -Brw da1 auto &prompt.root; disklabel -e da1 # create the `e' partition &prompt.root; newfs -d0 /dev/rda1e &prompt.root; mkdir -p /1 &prompt.root; vi /etc/fstab # add an entry for /dev/da1e &prompt.root; mount /1 An alternate method is: &prompt.root; dd if=/dev/zero of=/dev/rda1 count=2 &prompt.root; disklabel /dev/rda1 | disklabel -BrR da1 /dev/stdin &prompt.root; newfs /dev/rda1e &prompt.root; mkdir -p /1 &prompt.root; vi /etc/fstab # add an entry for /dev/da1e &prompt.root; mount /1 Virtual Disks: Network, Memory, and File-Based Filesystems Besides the disks you physically insert into your computer; floppies, CDs, hard drives, and so forth, other forms of disks are understood by FreeBSD - the virtual disks. These include network filesystems such as the Network Filesystem and Coda, memory-based filesystems such as md and file-backed filesystems created by vnconfig. vnconfig: file-backed filesystem &man.vnconfig.8; configures and enables vnode pseudo disk devices. A vnode is a representation of a file, and is the focus of file activity. This means that &man.vnconfig.8; uses files to create and operate a filesystem. One possible use is the mounting of floppy or CD images kept in files. To mount an existing filesystem image: Using vnconfig to mount an existing filesystem image &prompt.root; vnconfig vn0 diskimage &prompt.root; mount /dev/vn0c /mnt To create a new filesystem image with vnconfig: Creating a New File-Backed Disk with vnconfig &prompt.root; dd if=/dev/zero of=newimage bs=1k count=5k 5120+0 records in 5120+0 records out &prompt.root; vnconfig -s labels -c vn0 newimage &prompt.root; disklabel -r -w vn0 auto &prompt.root; newfs vn0c Warning: 2048 sector(s) in last cylinder unallocated /dev/rvn0c: 10240 sectors in 3 cylinders of 1 tracks, 4096 sectors 5.0MB in 1 cyl groups (16 c/g, 32.00MB/g, 1280 i/g) super-block backups (for fsck -b #) at: 32 &prompt.root; mount /dev/vn0c /mnt &prompt.root; df /mnt Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/vn0c 4927 1 4532 0% /mnt md: Memory Filesystem md is a simple, efficient means to do memory filesystems. Simply take a filesystem you've prepared with, for example, &man.vnconfig.8;, and: md memory disk &prompt.root; dd if=newimage of=/dev/md0 5120+0 records in 5120+0 records out &prompt.root; mount /dev/md0c /mnt &prompt.root; df /mnt Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/md0c 4927 1 4532 0% /mnt Disk Quotas Quotas are an optional feature of the operating system that allow you to limit the amount of disk space and/or the number of files a user, or members of a group, may allocate on a per-file system basis. This is used most often on timesharing systems where it is desirable to limit the amount of resources any one user or group of users may allocate. This will prevent one user from consuming all of the available disk space. Configuring Your System to Enable Disk Quotas Before attempting to use disk quotas it is necessary to make sure that quotas are configured in your kernel. This is done by adding the following line to your kernel configuration file: options QUOTA The stock GENERIC kernel does not have this enabled by default, so you will have to configure, build and install a custom kernel in order to use disk quotas. Please refer to the Configuring the FreeBSD Kernel section for more information on kernel configuration. Next you will need to enable disk quotas in /etc/rc.conf. This is done by adding the line: enable_quotas=“YES” For finer control over your quota startup, there is an additional configuration variable available. Normally on bootup, the quota integrity of each file system is checked by the quotacheck program. The quotacheck facility insures that the data in the quota database properly reflects the data on the file system. This is a very time consuming process that will significantly affect the time your system takes to boot. If you would like to skip this step, a variable is made available for the purpose: check_quotas=“NO” If you are running FreeBSD prior to 3.2-RELEASE, the configuration is simpler, and consists of only one variable. Set the following in your /etc/rc.conf: check_quotas=“YES” Finally you will need to edit /etc/fstab to enable disk quotas on a per-file system basis. This is where you can either enable user or group quotas or both for all of your file systems. To enable per-user quotas on a file system, add the userquota option to the options field in the /etc/fstab entry for the file system you want to to enable quotas on. For example: /dev/da1s2g /home ufs rw,userquota 1 2 Similarly, to enable group quotas, use the groupquota option instead of the userquota keyword. To enable both user and group quotas, change the entry as follows: /dev/da1s2g /home ufs rw,userquota,groupquota 1 2 By default the quota files are stored in the root directory of the file system with the names quota.user and quota.group for user and group quotas respectively. See man fstab for more information. Even though that man page says that you can specify an alternate location for the quota files, this is not recommended because the various quota utilities do not seem to handle this properly. At this point you should reboot your system with your new kernel. /etc/rc will automatically run the appropriate commands to create the initial quota files for all of the quotas you enabled in /etc/fstab, so there is no need to manually create any zero length quota files. In the normal course of operations you should not be required to run the quotacheck, quotaon, or quotaoff commands manually. However, you may want to read their man pages just to be familiar with their operation. Setting Quota Limits Once you have configured your system to enable quotas, verify that they really are enabled. An easy way to do this is to run: &prompt.root; quota -v You should see a one line summary of disk usage and current quota limits for each file system that quotas are enabled on. You are now ready to start assigning quota limits with the edquota command. You have several options on how to enforce limits on the amount of disk space a user or group may allocate, and how many files they may create. You may limit allocations based on disk space (block quotas) or number of files (inode quotas) or a combination of both. Each of these limits are further broken down into two categories; hard and soft limits. A hard limit may not be exceeded. Once a user reaches their hard limit they may not make any further allocations on the file system in question. For example, if the user has a hard limit of 500 blocks on a file system and is currently using 490 blocks, the user can only allocate an additional 10 blocks. Attempting to allocate an additional 11 blocks will fail. Soft limits on the other hand can be exceeded for a limited amount of time. This period of time is known as the grace period, which is one week by default. If a user stays over his or her soft limit longer than their grace period, the soft limit will turn into a hard limit and no further allocations will be allowed. When the user drops back below the soft limit, the grace period will be reset. The following is an example of what you might see when you run the edquota command. When the edquota command is invoked, you are placed into the editor specified by the EDITOR environment variable, or in the vi editor if the EDITOR variable is not set, to allow you to edit the quota limits. &prompt.root; edquota -u test Quotas for user test: /usr: blocks in use: 65, limits (soft = 50, hard = 75) inodes in use: 7, limits (soft = 50, hard = 60) /usr/var: blocks in use: 0, limits (soft = 50, hard = 75) inodes in use: 0, limits (soft = 50, hard = 60) You will normally see two lines for each file system that has quotas enabled. One line for the block limits, and one line for inode limits. Simply change the value you want updated to modify the quota limit. For example, to raise this users block limit from a soft limit of 50 and a hard limit of 75 to a soft limit of 500 and a hard limit of 600, change: /usr: blocks in use: 65, limits (soft = 50, hard = 75) to: /usr: blocks in use: 65, limits (soft = 500, hard = 600) The new quota limits will be in place when you exit the editor. Sometimes it is desirable to set quota limits on a range of uids. This can be done by use of the option on the edquota command. First, assign the desired quota limit to a user, and then run edquota -p protouser startuid-enduid. For example, if user test has the desired quota limits, the following command can be used to duplicate those quota limits for uids 10,000 through 19,999: &prompt.root; edquota -p test 10000-19999 See man edquota for more detailed information. Checking Quota Limits and Disk Usage You can use either the quota or the repquota commands to check quota limits and disk usage. The quota command can be used to check individual user and group quotas and disk usage. Only the super-user may examine quotas and usage for other users, or for groups that they are not a member of. The repquota command can be used to get a summary of all quotas and disk usage for file systems with quotas enabled. The following is some sample output from the quota -v command for a user that has quota limits on two file systems. Disk quotas for user test (uid 1002): Filesystem blocks quota limit grace files quota limit grace /usr 65* 50 75 5days 7 50 60 /usr/var 0 50 75 0 50 60 On the /usr file system in the above example this user is currently 15 blocks over their soft limit of 50 blocks and has 5 days of their grace period left. Note the asterisk * which indicates that the user is currently over their quota limit. Normally file systems that the user is not using any disk space on will not show up in the output from the quota command, even if they have a quota limit assigned for that file system. The option will display those file systems, such as the /usr/var file system in the above example. Quotas over NFS Quotas are enforced by the quota subsystem on the NFS server. The &man.rpc.rquotad.8; daemon makes quota information available to the &man.quota.1; command on NFS clients, allowing users on those machines to see their quota statistics. Enable rpc.rquotad in /etc/inetd.conf like so: rquotad/1 dgram rpc/udp wait root /usr/libexec/rpc.rquotad rpc.rquotad Now restart inetd: &prompt.root; kill -HUP `cat /var/run/inetd.pid` diff --git a/en_US.ISO8859-1/books/handbook/install/chapter.sgml b/en_US.ISO8859-1/books/handbook/install/chapter.sgml index c16349a995..1db73b7204 100644 --- a/en_US.ISO8859-1/books/handbook/install/chapter.sgml +++ b/en_US.ISO8859-1/books/handbook/install/chapter.sgml @@ -1,1617 +1,1637 @@ Installing FreeBSD Restructured, updated, and parts rewritten by &a.jim;, January 2000. Synopsis The following chapter will attempt to guide you through the install of FreeBSD on your system. It can be installed through a variety of methods, including anonymous FTP (assuming you have network connectivity via modem or local network), CDROM, floppy disk, tape, an MS-DOS partition, or even NFS. No matter which method you choose, you will need to get started by creating the installation disks as described in the next section. By booting into the FreeBSD installer, even if you are not planning on installing FreeBSD right away, will provide important information about compatibility with your hardware. This information may dictate which installation options are even possible for you. It can also provide clues early-on in the process to potential problems you may come across later. If you plan to install FreeBSD via anonymous FTP, the only thing you will need are the installation floppies. The install program itself will handle anything else that is required. For more information about obtaining FreeBSD, see the Obtaining FreeBSD section of the Appendix. By now, you are probably wondering what exactly it is you need to do. Continue on to the installation guide. Installation Guide The following sections will guide you through preparing for and actually installing FreeBSD. If you find something missing, please let us know about it by sending email to the &a.doc;. Preparing for the Installation There are various things you should do in preparation for the install. The following describes what needs to be done prior to each type of installation. The first thing you should do is make sure your hardware is supported by FreeBSD. The list of supported hardware should come in handy here. ;-) It would also be a good idea to make a list of any “special” cards you have installed, such as SCSI controllers, ethernet cards, sound cards, etc.. The list should include their IRQs and IO port addresses. Creating the Boot Floppies Please read the installation boot image information before proceeding. To make the installation boot disks from the image files, do the following: The first thing you will need to do is download the image files. These can be retrieved from the floppies directory of the FreeBSD FTP site or your local mirror. If you are installing from an MS-DOS partition, download the fdimage.exe program or get it from tools\fdimage.exe on the CDROM and then run it like so: E:\> tools\fdimage floppies\kern.flp a: The fdimage program will format the A: drive and then copy kern.flp to it (assuming that you are at the top level of a FreeBSD distribution and the floppy images live in a floppies subdirectory, which is typically the case). If you are using a UNIX-based system to create the boot floppies, do the following: &prompt.root; dd if=kern.flp of=disk_device disk_device is the /dev entry for the floppy drive. On FreeBSD, this is /dev/rfd0 for the A: drive and /dev/rfd1 for the B: drive. With the kern.flp disk in your floppy drive, reboot your computer. You will be prompted to insert the mfsroot.flp, after which the installation will proceed normally. Before Installing from CDROM If your CDROM is of an unsupported type, please skip ahead to the MS-DOS Preparation section. There is not a whole lot of preparation needed if you are installing from one of Walnut Creek CDROM's FreeBSD CDROMs (other CDROM distributions may work as well, though we cannot say for certain as we have no hand or say in how they created). You can either boot into the CD installation directly from DOS using the install.bat or you can make floppies with the makeflp.bat command. If the CD has El Torito boot support and your system supports booting directly from the CDROM drive (many older systems do NOT), simply insert the first FreeBSD of the set into the drive and reboot your system. You will be put into the install menu directly from the CD. If you are installing from an MS-DOS partition and have the proper drivers to access your CD, run the install.bat script provided on the CDROM. This will attempt to boot the FreeBSD installation directly from DOS. You must do this from actual DOS (i.e., boot in DOS mode) and not from a DOS window under Windows. For the easiest interface of all (from DOS), type view. This will bring up a DOS menu utility that leads you through all of the available options. If you are creating the boot floppies from a UNIX machine, see the Creating the Boot Floppies section of this guide for examples. Once you have booted from DOS or floppy, you should then be able to select CDROM as the media type during the install process and load the entire distribution from CDROM. No other types of installation media should be required. After your system is fully installed and you have rebooted (from the hard disk), you can mount the CDROM at any time by typing: &prompt.root; mount /cdrom Before removing the CD from the drive again, you must first unmount it. This is done with the following command: &prompt.root; umount /cdrom Do not just remove it from the drive! Before invoking the installation, be sure that the CDROM is in the drive so that the install probe can find it. This is also true if you wish the CDROM to be added to the default system configuration automatically during the install (whether or not you actually use it as the installation media). Finally, if you would like people to be able to FTP install FreeBSD directly from the CDROM in your machine, you will find it quite easy. After the machine is fully installed, you simply need to add the following line to the password file (using the vipw command): ftp:*:99:99::0:0:FTP:/cdrom:/nonexistent Anyone with network connectivity to your machine can now chose a media type of FTP and type in ftp://your machine after picking “Other” in the FTP sites menu during the install. Before installing from Floppies If you must install from floppy disk (which we suggest you do NOT do), either due to unsupported hardware or simply because you insist on doing things the hard way, you must first prepare some floppies for the install. At a minimum, you will need as many 1.44MB or 1.2MB floppies as it takes to hold all the files in the bin (binary distribution) directory. If you are preparing the floppies from DOS, then they MUST be formatted using the MS-DOS FORMAT command. If you are using Windows, use the Windows File Manager format command. Do NOT trust factory pre-formatted floppies! Format them again yourself, just to be sure. Many problems reported by our users in the past have resulted from the use of improperly formatted media, which is why we are making a point of it now. If you are creating the floppies on another FreeBSD machine, a format is still not a bad idea, though you do not need to put a DOS filesystem on each floppy. You can use the disklabel and newfs commands to put a UFS filesystem on them instead, as the following sequence of commands (for a 3.5" 1.44MB floppy) illustrate: &prompt.root; fdformat -f 1440 fd0.1440 &prompt.root; disklabel -w -r fd0.1440 floppy3 &prompt.root; newfs -t 2 -u 18 -l 1 -i 65536 /dev/rfd0 Use fd0.1200 and floppy5 for 5.25" 1.2MB disks. Then you can mount and write to them like any other filesystem. After you have formatted the floppies, you will need to copy the files to them. The distribution files are split into chunks conveniently sized so that 5 of them will fit on a conventional 1.44MB floppy. Go through all your floppies, packing as many files as will fit on each one, until you have all of the distributions you want packed up in this fashion. Each distribution should go into a subdirectory on the floppy, e.g.: a:\bin\bin.aa, a:\bin\bin.ab, and so on. Once you come to the Media screen during the install process, select “Floppy” and you will be prompted for the rest. Before Installing from MS-DOS To prepare for an installation from an MS-DOS partition, copy the files from the distribution into a directory named, for example, c:\FreeBSD. The directory structure of the CDROM or FTP site must be partially reproduced within this directory, so we suggest using the DOS xcopy command if you are copying it from a CD. For example, to prepare for a minimal installation of FreeBSD: C:\> md c:\FreeBSD C:\> xcopy /s e:\bin c:\FreeBSD\bin\ C:\> xcopy /s e:\manpages c:\FreeBSD\manpages\ Assuming that C: is where you have free space and E: is where your CDROM is mounted. For as many distributions you wish to install from an MS-DOS partition (and you have the free space for), install each one under c:\FreeBSD — the BIN distribution is the only one required for a minimum installation. Before Installing from QIC/SCSI Tape Installing from tape is probably the easiest method, short of an online FTP install or CDROM install. The installation program expects the files to be simply tar'ed onto the tape, so after getting all of the distribution files you are interested in, simply tar them onto the tape like so: &prompt.root; cd /freebsd/distdir &prompt.root; tar cvf /dev/rwt0 dist1 ... dist2 When you go to do the installation, you should also make sure that you leave enough room in some temporary directory (which you will be allowed to choose) to accommodate the full contents of the tape you have created. Due to the non-random access nature of tapes, this method of installation requires quite a bit of temporary storage. You should expect to require as much temporary storage as you have stuff written on tape. When starting the installation, the tape must be in the drive before booting from the boot floppy. The installation probe may otherwise fail to find it. Before Installing over a Network There are three types of network installations you can do. Serial port (SLIP or PPP), Parallel port (PLIP (laplink cable)), or Ethernet (a standard ethernet controller (includes some PCMCIA)). The SLIP support is rather primitive, and limited primarily to hard-wired links, such as a serial cable running between a laptop computer and another computer. The link should be hard-wired as the SLIP installation does not currently offer a dialing capability; that facility is provided with the PPP utility, which should be used in preference to SLIP whenever possible. If you are using a modem, then PPP is almost certainly your only choice. Make sure that you have your service provider's information handy as you will need to know it fairly early in the installation process. You will also need to know how to dial your ISP using the “AT commands” specific to your modem, as the PPP dialer provides only a very simple terminal emulator. If you are using PAP or CHAP, you will need to type the necessary set authname and set authkey commands before typing term. Refer to the user-ppp handbook and FAQ entries for further information. If you have problems, logging can be directed to the screen using the command set log local .... If a hard-wired connection to another FreeBSD (2.0-R or later) machine is available, you might also consider installing over a “laplink” parallel port cable. The data rate over the parallel port is much higher than what is typically possible over a serial line (up to 50kbytes/sec), thus resulting in a quicker installation. Finally, for the fastest possible network installation, an ethernet adapter is always a good choice! FreeBSD supports most common PC ethernet cards; a table of supported cards (and their required settings) is provided in the Supported Hardware list. If you are using one of the supported PCMCIA ethernet cards, also be sure that it is plugged in before the laptop is powered on! FreeBSD does not, unfortunately, currently support hot insertion of PCMCIA cards during installation. You will also need to know your IP address on the network, the netmask value for your address class, and the name of your machine. If you are installing over a PPP connection and do not have a static IP, fear not, the IP address can be dynamically assigned by your ISP. Your system administrator can tell you which values to use for your particular network setup. If you will be referring to other hosts by name rather than IP address, you will also need a name server and possibly the address of a gateway (if you are using PPP, it is your provider's IP address) to use in talking to it. If you do not know the answers to all or most of these questions, then you should really probably talk to your system administrator before trying this type of installation. Before Installing via NFS The NFS installation is fairly straight-forward. Simply copy the FreeBSD distribution files you want onto a server somewhere and then point the NFS media selection at it. If this server supports only “privileged port” (as is generally the default for Sun workstations), you will need to set this option in the Options menu before installation can proceed. If you have a poor quality ethernet card which suffers from very slow transfer rates, you may also wish to toggle the appropriate Options flag. In order for NFS installation to work, the server must support subdir mounts, e.g., if your FreeBSD 3.4 distribution directory lives on:ziggy:/usr/archive/stuff/FreeBSD, then ziggy will have to allow the direct mounting of /usr/archive/stuff/FreeBSD, not just /usr or /usr/archive/stuff. In FreeBSD's /etc/exports file, this is controlled by the . Other NFS servers may have different conventions. If you are getting “permission denied” messages from the server, then it is likely that you do not have this enabled properly. Before Installing via FTP FTP installation may be done from any FreeBSD mirror site containing a reasonably up-to-date version of FreeBSD. A full list of FTP mirrors located all over the world is provided during the install process. If you are installing from an FTP site not listed in this menu, or are having trouble getting your name server configured properly, you can also specify a URL to use by selecting the choice labeled “Other” in that menu. You can also use the IP address of a machine you wish to install from, so the following would work in the absence of a name server: ftp://165.113.121.81/pub/FreeBSD/&rel.current;-RELEASE There are two FTP installation modes you can choose from, active or passive FTP. FTP Active For all FTP transfers, use “Active” mode. This will not work through firewalls, but will often work with older FTP servers that do not support passive mode. If your connection hangs with passive mode (the default), try active! FTP Passive For all FTP transfers, use “Passive” mode. This allows the user to pass through firewalls that do not allow incoming connections on random port addresses. Active and passive modes are not the same as a “proxy” connection, where a proxy FTP server is listening and forwarding FTP requests! For a proxy FTP server, you should usually give the name of the server you really want as a part of the username, after an “@” sign. The proxy server then “fakes” the real server. For example, assuming you want to install from ftp.FreeBSD.org, using the proxy FTP server foo.bar.com, listening on port 1024. In this case, you go to the options menu, set the FTP username to ftp@ftp.FreeBSD.org, and the password to your email address. As your installation media, you specify FTP (or passive FTP, if the proxy supports it), and the URL ftp://foo.bar.com:1234/pub/FreeBSD. Since /pub/FreeBSD from ftp.FreeBSD.org is proxied under foo.bar.com, you are able to install from that machine (which will fetch the files from ftp.FreeBSD.org as your installation requests them. + + + Check your BIOS drive numbering + + If you have used features in your BIOS to renumber your disk + drives without recabling them then you should read first to ensure you do not + confused. + Installing FreeBSD Once you have completed the pre-installation step relevant to your situation, you are ready to install FreeBSD! Although you should not experience any difficulties, there is always the chance you might, no matter how slight it is. If this is the case in your situation, then you may wish to go back and re-read the relevant preparation section or sections. Perhaps you will come across something you missed the first time. If you are having hardware problems, or FreeBSD refuses to boot at all, read the Hardware Guide on the boot floppy for a list of possible solutions. The FreeBSD boot floppies contain all of the online documentation you should need to be able to navigate through an installation. If it does not, please let us know what you found to be the most confusing or most lacking. Send your comments to the &a.doc;. It is the objective of the installation program (sysinstall) to be self-documenting enough that painful “step-by-step” guides are no longer necessary. It may take us a little while to reach that objective, but nonetheless, it is still our objective :-) Meanwhile, you may also find the following “typical installation sequence” to be helpful: Boot the kern.flp floppy and when asked, remove it and insert the mfsroot.flp and hit return. After a boot sequence which can take anywhere from 30 seconds to 3 minutes, depending on your hardware, you should be presented with a menu of initial choices. If the kern.flp floppy does not boot at all or the boot hangs at some stage, read the Q&A section of the Hardware Guide on the floppy for possible causes. Press F1. You should see some basic usage instructions on the menu screen and general navigation. If you have not used this menu system before then please read this thoroughly. Select the Options item and set any special preferences you may have. Select a Novice, Custom, or Express install, depending on whether or not you would like the installation to help you through a typical installation, give you a high degree of control over each step, or simply whizz through it (using reasonable defaults when possible) as fast as possible. If you have never used FreeBSD before, the Novice installation method is most recommended. The final configuration menu choice allows you to further configure your FreeBSD installation by giving you menu-driven access to various system defaults. Some items, like networking, may be especially important if you did a CDROM, tape, or floppy install and have not yet configured your network interfaces (assuming you have any). Properly configuring such interfaces here will allow FreeBSD to come up on the network when you first reboot from the hard disk. Supported Hardware FreeBSD currently runs on a wide variety of ISA, VLB, EISA, and PCI bus based PCs, ranging from the 386SX to Pentium class machines (though the 386SX is not recommended). Support for generic IDE or ESDI drive configurations, various SCSI controllers, and network and serial cards is also provided. In order to run FreeBSD, a recommmended minimum of eight megabytes of RAM is suggested. Sixteen megabytes is the preferred amount of RAM as you may have some trouble with anything less than sixteen depending on your hardware. What follows is a list of hardware currently known to work with FreeBSD. There may be other hardware that works as well, but we have simply not received any confirmation of it.

FreeBSD currently does NOT support IBM's microchannel (MCA) bus. Troubleshooting The following section covers basic installation troubleshooting, such as common problems people have reported. There are also a few questions and answers for people wishing to dual-boot FreeBSD with MS-DOS. What to do if something goes wrong... Due to various limitations of the PC architecture, it is impossible for probing to be 100% reliable, however, there are a few things you can do if it fails. Check the supported hardware list to make sure your hardware is supported. If your hardware is supported and you still experience lock-ups or other problems, reset your computer, and when the visual kernel configuration option is given, choose it. This will allow you to go through your hardware and supply information to the system about it. The kernel on the boot disks is configured assuming that most hardware devices are in their factory default configuration in terms of IRQs, IO addresses, and DMA channels. If your hardware has been reconfigured, you will most likely need to use the configuration editor to tell FreeBSD where to find things. It is also possible that a probe for a device not present will cause a later probe for another device that is present to fail. In that case, the probes for the conflicting driver(s) should be disabled. Do not disable any drivers you will need during the installation, such as your screen (sc0). If the installation wedges or fails mysteriously after leaving the configuration editor, you have probably removed or changed something you should not have. Reboot and try again. In configuration mode, you can: List the device drivers installed in the kernel. Change device drivers for hardware that is not present in your system. Change IRQs, DRQs, and IO port addresses used by a device driver. After adjusting the kernel to match your hardware configuration, type Q to boot with the new settings. Once the installation has completed, any changes you made in the configuration mode will be permanent so you do not have to reconfigure every time you boot. It is still highly likely that you will eventually want to build a custom kernel. MS-DOS User's Questions and Answers Many users wish to install FreeBSD on PCs inhabited by MS-DOS. Here are some commonly asked questions about installing FreeBSD on such systems. Help, I have no space! Do I need to delete everything first? If your machine is already running MS-DOS and has little or no free space available for the FreeBSD installation, all hope is not lost! You may find the FIPS utility, provided in the tools directory on the FreeBSD CDROM or various FreeBSD FTP sites to be quite useful. FIPS allows you to split an existing MS-DOS partition into two pieces, preserving the original partition and allowing you to install onto the second free piece. You first defragment your MS-DOS partition using the DOS 6.XX DEFRAG utility or the Norton Disk Tools, then run FIPS. It will prompt you for the rest of the information it needs. Afterwards, you can reboot and install FreeBSD on the new free slice. See the Distributions menu for an estimate of how much free space you will need for the kind of installation you want. Can I use compressed MS-DOS filesystems from FreeBSD? No. If you are using a utility such as Stacker(tm) or DoubleSpace(tm), FreeBSD will only be able to use whatever portion of the filesystem you leave uncompressed. The rest of the filesystem will show up as one large file (the stacked/double spaced file!). Do not remove that file or you will probably regret it greatly! It is probably better to create another uncompressed primary MS-DOS partition and use this for communications between MS-DOS and FreeBSD. Can I mount my extended MS-DOS partition? Yes. DOS extended partitions are mapped in at the end of the other “slices” in FreeBSD, e.g., your D: drive might be /dev/da0s5, your E: drive, /dev/da0s6, and so on. This example assumes, of course, that your extended partition is on SCSI drive 0. For IDE drives, substitute wd for da appropriately. You otherwise mount extended partitions exactly like you would any other DOS drive, for example: &prompt.root; mount -t msdos /dev/da0s5 /dos_d + + diff --git a/en_US.ISO_8859-1/books/handbook/disks/chapter.sgml b/en_US.ISO_8859-1/books/handbook/disks/chapter.sgml index 71674e34ac..4bcdeb6a17 100644 --- a/en_US.ISO_8859-1/books/handbook/disks/chapter.sgml +++ b/en_US.ISO_8859-1/books/handbook/disks/chapter.sgml @@ -1,783 +1,882 @@ Disks Synopsis This chapter covers how to use disks, whether physical, memory, or networked, on FreeBSD. + + BIOS Drive Numbering + + Before you install and configure FreeBSD on your system, there is an + important subject that you should be aware of if, especially if you have + multiple hard drives. + + In a PC running DOS or any of the BIOS-dependent operating systems + (WINxxx), the BIOS is able to abstract the normal disk drive order, and + the operating system goes along with the change.

Bill installs a single SCSI drive as SCSI unit zero, and + installs FreeBSD on it. + + Fred begins using the system, but after several days notices that + the older SCSI drive is reporting numerous soft errors, and reports + this fact to Bill. + + After several more days, Bill decides it's time to address the + situation, so he grabs an identical SCSI drive from the disk drive + "archive" in the back room. An initial surface scan indicates that + this drive is functioning well, so Bill installs this drive as SCSI + unit four, and makes an image copy from drive zero to drive four. Now + that the new drive is installed and functioning nicely, Bill decides + that it's a good idea to start using it, so he uses features in the + SCSI BIOS to re-order the disk drives so that the system boots from + SCSI unit four. FreeBSD boots and runs just fine. + + Fred continues his work for several days, and soon Bill and Fred + decide that it's time for a new adventure -- time to upgrade to a + newer version of FreeBSD. Bill removes SCSI unit zero because it was + a bit flakey, and replaces it with another identical disk drive from + the "archive." Bill then installs the new version of FreeBSD onto the + new SCSI unit zero using Fred's magic internet FTP floppies. The + installation goes well. + + Fred uses the new version of FreeBSD for a few days, and certifies + that it is good enough for use in the engineering department...it's + time to copy all of his work from the old version. So Fred mounts + SCSI unit four (the latest copy of the older FreeBSD version). Fred + is dismayed to find that none of his precious work is present on SCSI + unit four. + + Where did the data go? + + When Bill made an image copy of the original SCSI unit zero onto + SCSI unit four, unit four became the "new clone," When Bill + re-ordered the SCSI BIOS so that he could boot from SCSI unit four, he + was only fooling himself. FreeBSD was still running on SCSI unit zero. + Making this kind of BIOS change will cause some or all of the Boot and + Loader code to be fetched from the selected BIOS drive, but when the + FreeBSD kernel drivers take-over, the BIOS drive numbering will be + ignored, and FreeBSD will transition back to normal drive numbering. + In the illustration at hand, the system continued to operate on the + original SCSI unit zero, and all of Fred's data was there, not on SCSI + unit four. The fact that the system appeared to be running on SCSI + unit four was simply an artifact of human expectations. + + We are delighted to mention that no data bytes were killed or + harmed in any way by our discovery of this phenomenon. The older SCSI + unit zero was retrieved from the bonepile, and all of Fred's work was + returned to him, (and now Bill knows that he can count as high as + zero). + + Although SCSI drives were used in this illustration, the concepts + apply equally to IDE drives. + + + Disk Naming Physical drives come in two main flavours, IDE, or SCSI; but there are also drives backed by RAID controllers, flash memory, and so forth. Since these behave quite differently, they have their own drivers and devices. Physical Disk Naming Conventions Drive type Drive device name IDE hard drives ad in 4.0-RELEASE, wd before 4.0-RELEASE.

Slices and Partitions Physical disks usually contain slices, unless they are dangerously dedicated. Slice numbers follow the device name, prefixed with an s: da0s1. Slices, dangerously dedicated physical drives, and other drives contain partitions, which represented as letters from a to h. b is reserved for swap partitions, and c is an unused partition the size of the entire slice or drive. This is explained in . Mounting and Unmounting Filesystems The filesystem is best visualized as a tree, rooted, as it were, at /. /dev, /usr, and the other directories in the root directory are branches, which may have their own branches, such as /usr/local, and so on. There are various reasons to house certain of these directories on separate filesystems. /var contains log, spool, and various types of temporary files, and as such, may get filled up. Filling up the root filesystem isn't a good idea, so splitting /var from / is often a good idea. Another common reason to contain certain directory trees on other filesystems is if they are to be housed on separate physical disks, or are separate virtual disks, such as Network File System mounts, or CDROM drives. The fstab File During the boot process, filesystems listed in /etc/fstab are automatically mounted (unless they are listed with ). The /etc/fstab file contains a list of lines of the following format: device /mount-point fstype options dumpfreq passno device is a device name (which should exist), as explained in the Disk naming conventions above. mount-point is a directory (which should exist), on which to mount the filesystem. fstype is the filesystem type to pass to &man.mount.8;. The default FreeBSD filesystem is ufs. options is either for read-write filesystems, or for read-only filesystems, followed by any other options that may be needed. A common option is for filesystems not normally mounted during the boot sequence. Other options in the &man.mount.8; manual page. dumpfreq is the number of days the filesystem should be dumped, and passno is the pass number during which the filesystem is mounted during the boot sequence. The mount Command The &man.mount.8; command is what is ultimately used to mount filesystems. In its most basic form, you use: &prompt.root; mount device mountpoint There are plenty of options, as mentioned in the &man.mount.8; manual page, but the most common are: mount options Mount all filesystems in /etc/fstab, as modified by , if given. Do everything but actually mount the filesystem. Force the mounting the filesystem. Mount the filesystem read-only. fstype Mount the given filesystem as the given filesystem type, or mount only filesystems of the given type, if given the option. ufs is the default filesystem type. Update mount options on the filesystem. Be verbose. Mount the filesystem read-write. The takes a comma-separated list of the options, including the following: nodev Do not interpret special devices on the filesystem. Useful security option. noexec Do not allow execution of binaries on this filesystem. Useful security option. nosuid Do not interpret setuid or setgid flags on the filesystem. Useful security option. The umount Command The umount command takes, as a parameter, one of a mountpoint, a device name, or the or option. All forms take to force unmounting, and for verbosity. and are used to unmount all mounted filesystems, possibly modified by the filesystem types listed after . , however, doesn't attempt to unmount the root filesystem. Adding Disks Originally contributed by &a.obrien; 26 April 1998 Lets say we want to add a new SCSI disk to a machine that currently only has a single drive. First turn off the computer and install the drive in the computer following the instructions of the computer, controller, and drive manufacturer. Due the wide variations of procedures to do this, the details are beyond the scope of this document. Login as user root. After you've installed the drive, inspect /var/run/dmesg.boot to ensure the new disk was found. Continuing with our example, the newly added drive will be da1 and we want to mount it on /1. (if you are adding an IDE drive substitute wd for da) Because FreeBSD runs on IBM-PC compatible computers, it must take into account the PC BIOS partitions. These are different from the traditional BSD partitions. A PC disk has up to four BIOS partition entries. If the disk is going to be truly dedicated to FreeBSD, you can use the dedicated mode. Otherwise, FreeBSD will have to live with in one of the PC BIOS partitions. FreeBSD calls the PC BIOS partitions, slices so as not to confuse them with traditional BSD partitions. You may also use slices on a disk that is dedicated to FreeBSD, but used in a computer that also has another operating system installed. This is to not confuse the fdisk utility of the other operating system. In the slice case the drive will be added as /dev/da1s1e. This is read as: SCSI disk, unit number 1 (second SCSI disk), slice 1 (PC BIOS partition 1), and e BSD partition. In the dedicated case, the drive will be added simply as /dev/da1e. Using sysinstall You may use /stand/sysinstall to partition and label a new disk using its easy to use menus. Either login as user root or use the su command. Run /stand/sysinstall and enter the Configure menu. With in the FreeBSD Configuration Menu, scroll down and select the Partition item. Next you should be presented with a list of hard drives installed in your system. If you do not see da1 listed, you need to recheck your physical installation and dmesg output in the file /var/run/dmesg.boot. Select da1 to enter the FDISK Partition Editor. Choose A to use the entire disk for FreeBSD. When asked if you want to remain cooperative with any future possible operating systems, answer YES. Write the changes to the disk using W. Now exit the FDISK editor using q. Next you will be asked about the Master Boot Record. Since you are adding a disk to an already running system, choose None. Next enter the Disk Label Editor. This is where you will create the traditional BSD partitions. A disk can have up to eight partitions, labeled a-h. A few of the partition labels have special uses. The a partition is used for the root partition (/). Thus only your system disk (e.g, the disk you boot from) should have an a partition. The b partition is used for swap partitions, and you may have many disks with swap partitions. The c partition addresses the entire disk in dedicated mode, or the entire FreeBSD slice in slice mode. The other partitions are for general use. Sysinstall's Label editor favors the e partition for non-root, non-swap partitions. With in the Label editor, create a single file system using C. When prompted if this will be a FS (file system) or swap, choose FS and give a mount point (e.g, /mnt). When adding a disk in post-install mode, Sysinstall will not create entries in /etc/fstab for you, so the mount point you specify isn't important. You are now ready to write the new label to the disk and create a file system on it. Do this by hitting W. Ignore any errors from Sysinstall that it could not mount the new partition. Exit the Label Editor and Sysinstall completely. The last step is to edit /etc/fstab to add an entry for your new disk. Using Command Line Utilities * Using Slices Dedicated If you will not be sharing the new drive with another operating system, you may use the dedicated mode. Remember this mode can confuse Microsoft operating systems; however, no damage will be done by them. IBM's OS/2 however, will “appropriate” any partition it finds which it doesn't understand. &prompt.root; dd if=/dev/zero of=/dev/rda1 bs=1k count=1 &prompt.root; disklabel -Brw da1 auto &prompt.root; disklabel -e da1 # create the `e' partition &prompt.root; newfs -d0 /dev/rda1e &prompt.root; mkdir -p /1 &prompt.root; vi /etc/fstab # add an entry for /dev/da1e &prompt.root; mount /1 An alternate method is: &prompt.root; dd if=/dev/zero of=/dev/rda1 count=2 &prompt.root; disklabel /dev/rda1 | disklabel -BrR da1 /dev/stdin &prompt.root; newfs /dev/rda1e &prompt.root; mkdir -p /1 &prompt.root; vi /etc/fstab # add an entry for /dev/da1e &prompt.root; mount /1 Virtual Disks: Network, Memory, and File-Based Filesystems Besides the disks you physically insert into your computer; floppies, CDs, hard drives, and so forth, other forms of disks are understood by FreeBSD - the virtual disks. These include network filesystems such as the Network Filesystem and Coda, memory-based filesystems such as md and file-backed filesystems created by vnconfig. vnconfig: file-backed filesystem &man.vnconfig.8; configures and enables vnode pseudo disk devices. A vnode is a representation of a file, and is the focus of file activity. This means that &man.vnconfig.8; uses files to create and operate a filesystem. One possible use is the mounting of floppy or CD images kept in files. To mount an existing filesystem image: Using vnconfig to mount an existing filesystem image &prompt.root; vnconfig vn0 diskimage &prompt.root; mount /dev/vn0c /mnt To create a new filesystem image with vnconfig: Creating a New File-Backed Disk with vnconfig &prompt.root; dd if=/dev/zero of=newimage bs=1k count=5k 5120+0 records in 5120+0 records out &prompt.root; vnconfig -s labels -c vn0 newimage &prompt.root; disklabel -r -w vn0 auto &prompt.root; newfs vn0c Warning: 2048 sector(s) in last cylinder unallocated /dev/rvn0c: 10240 sectors in 3 cylinders of 1 tracks, 4096 sectors 5.0MB in 1 cyl groups (16 c/g, 32.00MB/g, 1280 i/g) super-block backups (for fsck -b #) at: 32 &prompt.root; mount /dev/vn0c /mnt &prompt.root; df /mnt Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/vn0c 4927 1 4532 0% /mnt md: Memory Filesystem md is a simple, efficient means to do memory filesystems. Simply take a filesystem you've prepared with, for example, &man.vnconfig.8;, and: md memory disk &prompt.root; dd if=newimage of=/dev/md0 5120+0 records in 5120+0 records out &prompt.root; mount /dev/md0c /mnt &prompt.root; df /mnt Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/md0c 4927 1 4532 0% /mnt Disk Quotas Quotas are an optional feature of the operating system that allow you to limit the amount of disk space and/or the number of files a user, or members of a group, may allocate on a per-file system basis. This is used most often on timesharing systems where it is desirable to limit the amount of resources any one user or group of users may allocate. This will prevent one user from consuming all of the available disk space. Configuring Your System to Enable Disk Quotas Before attempting to use disk quotas it is necessary to make sure that quotas are configured in your kernel. This is done by adding the following line to your kernel configuration file: options QUOTA The stock GENERIC kernel does not have this enabled by default, so you will have to configure, build and install a custom kernel in order to use disk quotas. Please refer to the Configuring the FreeBSD Kernel section for more information on kernel configuration. Next you will need to enable disk quotas in /etc/rc.conf. This is done by adding the line: enable_quotas=“YES” For finer control over your quota startup, there is an additional configuration variable available. Normally on bootup, the quota integrity of each file system is checked by the quotacheck program. The quotacheck facility insures that the data in the quota database properly reflects the data on the file system. This is a very time consuming process that will significantly affect the time your system takes to boot. If you would like to skip this step, a variable is made available for the purpose: check_quotas=“NO” If you are running FreeBSD prior to 3.2-RELEASE, the configuration is simpler, and consists of only one variable. Set the following in your /etc/rc.conf: check_quotas=“YES” Finally you will need to edit /etc/fstab to enable disk quotas on a per-file system basis. This is where you can either enable user or group quotas or both for all of your file systems. To enable per-user quotas on a file system, add the userquota option to the options field in the /etc/fstab entry for the file system you want to to enable quotas on. For example: /dev/da1s2g /home ufs rw,userquota 1 2 Similarly, to enable group quotas, use the groupquota option instead of the userquota keyword. To enable both user and group quotas, change the entry as follows: /dev/da1s2g /home ufs rw,userquota,groupquota 1 2 By default the quota files are stored in the root directory of the file system with the names quota.user and quota.group for user and group quotas respectively. See man fstab for more information. Even though that man page says that you can specify an alternate location for the quota files, this is not recommended because the various quota utilities do not seem to handle this properly. At this point you should reboot your system with your new kernel. /etc/rc will automatically run the appropriate commands to create the initial quota files for all of the quotas you enabled in /etc/fstab, so there is no need to manually create any zero length quota files. In the normal course of operations you should not be required to run the quotacheck, quotaon, or quotaoff commands manually. However, you may want to read their man pages just to be familiar with their operation. Setting Quota Limits Once you have configured your system to enable quotas, verify that they really are enabled. An easy way to do this is to run: &prompt.root; quota -v You should see a one line summary of disk usage and current quota limits for each file system that quotas are enabled on. You are now ready to start assigning quota limits with the edquota command. You have several options on how to enforce limits on the amount of disk space a user or group may allocate, and how many files they may create. You may limit allocations based on disk space (block quotas) or number of files (inode quotas) or a combination of both. Each of these limits are further broken down into two categories; hard and soft limits. A hard limit may not be exceeded. Once a user reaches their hard limit they may not make any further allocations on the file system in question. For example, if the user has a hard limit of 500 blocks on a file system and is currently using 490 blocks, the user can only allocate an additional 10 blocks. Attempting to allocate an additional 11 blocks will fail. Soft limits on the other hand can be exceeded for a limited amount of time. This period of time is known as the grace period, which is one week by default. If a user stays over his or her soft limit longer than their grace period, the soft limit will turn into a hard limit and no further allocations will be allowed. When the user drops back below the soft limit, the grace period will be reset. The following is an example of what you might see when you run the edquota command. When the edquota command is invoked, you are placed into the editor specified by the EDITOR environment variable, or in the vi editor if the EDITOR variable is not set, to allow you to edit the quota limits. &prompt.root; edquota -u test Quotas for user test: /usr: blocks in use: 65, limits (soft = 50, hard = 75) inodes in use: 7, limits (soft = 50, hard = 60) /usr/var: blocks in use: 0, limits (soft = 50, hard = 75) inodes in use: 0, limits (soft = 50, hard = 60) You will normally see two lines for each file system that has quotas enabled. One line for the block limits, and one line for inode limits. Simply change the value you want updated to modify the quota limit. For example, to raise this users block limit from a soft limit of 50 and a hard limit of 75 to a soft limit of 500 and a hard limit of 600, change: /usr: blocks in use: 65, limits (soft = 50, hard = 75) to: /usr: blocks in use: 65, limits (soft = 500, hard = 600) The new quota limits will be in place when you exit the editor. Sometimes it is desirable to set quota limits on a range of uids. This can be done by use of the option on the edquota command. First, assign the desired quota limit to a user, and then run edquota -p protouser startuid-enduid. For example, if user test has the desired quota limits, the following command can be used to duplicate those quota limits for uids 10,000 through 19,999: &prompt.root; edquota -p test 10000-19999 See man edquota for more detailed information. Checking Quota Limits and Disk Usage You can use either the quota or the repquota commands to check quota limits and disk usage. The quota command can be used to check individual user and group quotas and disk usage. Only the super-user may examine quotas and usage for other users, or for groups that they are not a member of. The repquota command can be used to get a summary of all quotas and disk usage for file systems with quotas enabled. The following is some sample output from the quota -v command for a user that has quota limits on two file systems. Disk quotas for user test (uid 1002): Filesystem blocks quota limit grace files quota limit grace /usr 65* 50 75 5days 7 50 60 /usr/var 0 50 75 0 50 60 On the /usr file system in the above example this user is currently 15 blocks over their soft limit of 50 blocks and has 5 days of their grace period left. Note the asterisk * which indicates that the user is currently over their quota limit. Normally file systems that the user is not using any disk space on will not show up in the output from the quota command, even if they have a quota limit assigned for that file system. The option will display those file systems, such as the /usr/var file system in the above example. Quotas over NFS Quotas are enforced by the quota subsystem on the NFS server. The &man.rpc.rquotad.8; daemon makes quota information available to the &man.quota.1; command on NFS clients, allowing users on those machines to see their quota statistics. Enable rpc.rquotad in /etc/inetd.conf like so: rquotad/1 dgram rpc/udp wait root /usr/libexec/rpc.rquotad rpc.rquotad Now restart inetd: &prompt.root; kill -HUP `cat /var/run/inetd.pid` diff --git a/en_US.ISO_8859-1/books/handbook/install/chapter.sgml b/en_US.ISO_8859-1/books/handbook/install/chapter.sgml index c16349a995..1db73b7204 100644 --- a/en_US.ISO_8859-1/books/handbook/install/chapter.sgml +++ b/en_US.ISO_8859-1/books/handbook/install/chapter.sgml @@ -1,1617 +1,1637 @@ Installing FreeBSD Restructured, updated, and parts rewritten by &a.jim;, January 2000. Synopsis The following chapter will attempt to guide you through the install of FreeBSD on your system. It can be installed through a variety of methods, including anonymous FTP (assuming you have network connectivity via modem or local network), CDROM, floppy disk, tape, an MS-DOS partition, or even NFS. No matter which method you choose, you will need to get started by creating the installation disks as described in the next section. By booting into the FreeBSD installer, even if you are not planning on installing FreeBSD right away, will provide important information about compatibility with your hardware. This information may dictate which installation options are even possible for you. It can also provide clues early-on in the process to potential problems you may come across later. If you plan to install FreeBSD via anonymous FTP, the only thing you will need are the installation floppies. The install program itself will handle anything else that is required. For more information about obtaining FreeBSD, see the Obtaining FreeBSD section of the Appendix. By now, you are probably wondering what exactly it is you need to do. Continue on to the installation guide. Installation Guide The following sections will guide you through preparing for and actually installing FreeBSD. If you find something missing, please let us know about it by sending email to the &a.doc;. Preparing for the Installation There are various things you should do in preparation for the install. The following describes what needs to be done prior to each type of installation. The first thing you should do is make sure your hardware is supported by FreeBSD. The list of supported hardware should come in handy here. ;-) It would also be a good idea to make a list of any “special” cards you have installed, such as SCSI controllers, ethernet cards, sound cards, etc.. The list should include their IRQs and IO port addresses. Creating the Boot Floppies Please read the installation boot image information before proceeding. To make the installation boot disks from the image files, do the following: The first thing you will need to do is download the image files. These can be retrieved from the floppies directory of the FreeBSD FTP site or your local mirror. If you are installing from an MS-DOS partition, download the fdimage.exe program or get it from tools\fdimage.exe on the CDROM and then run it like so: E:\> tools\fdimage floppies\kern.flp a: The fdimage program will format the A: drive and then copy kern.flp to it (assuming that you are at the top level of a FreeBSD distribution and the floppy images live in a floppies subdirectory, which is typically the case). If you are using a UNIX-based system to create the boot floppies, do the following: &prompt.root; dd if=kern.flp of=disk_device disk_device is the /dev entry for the floppy drive. On FreeBSD, this is /dev/rfd0 for the A: drive and /dev/rfd1 for the B: drive. With the kern.flp disk in your floppy drive, reboot your computer. You will be prompted to insert the mfsroot.flp, after which the installation will proceed normally. Before Installing from CDROM If your CDROM is of an unsupported type, please skip ahead to the MS-DOS Preparation section. There is not a whole lot of preparation needed if you are installing from one of Walnut Creek CDROM's FreeBSD CDROMs (other CDROM distributions may work as well, though we cannot say for certain as we have no hand or say in how they created). You can either boot into the CD installation directly from DOS using the install.bat or you can make floppies with the makeflp.bat command. If the CD has El Torito boot support and your system supports booting directly from the CDROM drive (many older systems do NOT), simply insert the first FreeBSD of the set into the drive and reboot your system. You will be put into the install menu directly from the CD. If you are installing from an MS-DOS partition and have the proper drivers to access your CD, run the install.bat script provided on the CDROM. This will attempt to boot the FreeBSD installation directly from DOS. You must do this from actual DOS (i.e., boot in DOS mode) and not from a DOS window under Windows. For the easiest interface of all (from DOS), type view. This will bring up a DOS menu utility that leads you through all of the available options. If you are creating the boot floppies from a UNIX machine, see the Creating the Boot Floppies section of this guide for examples. Once you have booted from DOS or floppy, you should then be able to select CDROM as the media type during the install process and load the entire distribution from CDROM. No other types of installation media should be required. After your system is fully installed and you have rebooted (from the hard disk), you can mount the CDROM at any time by typing: &prompt.root; mount /cdrom Before removing the CD from the drive again, you must first unmount it. This is done with the following command: &prompt.root; umount /cdrom Do not just remove it from the drive! Before invoking the installation, be sure that the CDROM is in the drive so that the install probe can find it. This is also true if you wish the CDROM to be added to the default system configuration automatically during the install (whether or not you actually use it as the installation media). Finally, if you would like people to be able to FTP install FreeBSD directly from the CDROM in your machine, you will find it quite easy. After the machine is fully installed, you simply need to add the following line to the password file (using the vipw command): ftp:*:99:99::0:0:FTP:/cdrom:/nonexistent Anyone with network connectivity to your machine can now chose a media type of FTP and type in ftp://your machine after picking “Other” in the FTP sites menu during the install. Before installing from Floppies If you must install from floppy disk (which we suggest you do NOT do), either due to unsupported hardware or simply because you insist on doing things the hard way, you must first prepare some floppies for the install. At a minimum, you will need as many 1.44MB or 1.2MB floppies as it takes to hold all the files in the bin (binary distribution) directory. If you are preparing the floppies from DOS, then they MUST be formatted using the MS-DOS FORMAT command. If you are using Windows, use the Windows File Manager format command. Do NOT trust factory pre-formatted floppies! Format them again yourself, just to be sure. Many problems reported by our users in the past have resulted from the use of improperly formatted media, which is why we are making a point of it now. If you are creating the floppies on another FreeBSD machine, a format is still not a bad idea, though you do not need to put a DOS filesystem on each floppy. You can use the disklabel and newfs commands to put a UFS filesystem on them instead, as the following sequence of commands (for a 3.5" 1.44MB floppy) illustrate: &prompt.root; fdformat -f 1440 fd0.1440 &prompt.root; disklabel -w -r fd0.1440 floppy3 &prompt.root; newfs -t 2 -u 18 -l 1 -i 65536 /dev/rfd0 Use fd0.1200 and floppy5 for 5.25" 1.2MB disks. Then you can mount and write to them like any other filesystem. After you have formatted the floppies, you will need to copy the files to them. The distribution files are split into chunks conveniently sized so that 5 of them will fit on a conventional 1.44MB floppy. Go through all your floppies, packing as many files as will fit on each one, until you have all of the distributions you want packed up in this fashion. Each distribution should go into a subdirectory on the floppy, e.g.: a:\bin\bin.aa, a:\bin\bin.ab, and so on. Once you come to the Media screen during the install process, select “Floppy” and you will be prompted for the rest. Before Installing from MS-DOS To prepare for an installation from an MS-DOS partition, copy the files from the distribution into a directory named, for example, c:\FreeBSD. The directory structure of the CDROM or FTP site must be partially reproduced within this directory, so we suggest using the DOS xcopy command if you are copying it from a CD. For example, to prepare for a minimal installation of FreeBSD: C:\> md c:\FreeBSD C:\> xcopy /s e:\bin c:\FreeBSD\bin\ C:\> xcopy /s e:\manpages c:\FreeBSD\manpages\ Assuming that C: is where you have free space and E: is where your CDROM is mounted. For as many distributions you wish to install from an MS-DOS partition (and you have the free space for), install each one under c:\FreeBSD — the BIN distribution is the only one required for a minimum installation. Before Installing from QIC/SCSI Tape Installing from tape is probably the easiest method, short of an online FTP install or CDROM install. The installation program expects the files to be simply tar'ed onto the tape, so after getting all of the distribution files you are interested in, simply tar them onto the tape like so: &prompt.root; cd /freebsd/distdir &prompt.root; tar cvf /dev/rwt0 dist1 ... dist2 When you go to do the installation, you should also make sure that you leave enough room in some temporary directory (which you will be allowed to choose) to accommodate the full contents of the tape you have created. Due to the non-random access nature of tapes, this method of installation requires quite a bit of temporary storage. You should expect to require as much temporary storage as you have stuff written on tape. When starting the installation, the tape must be in the drive before booting from the boot floppy. The installation probe may otherwise fail to find it. Before Installing over a Network There are three types of network installations you can do. Serial port (SLIP or PPP), Parallel port (PLIP (laplink cable)), or Ethernet (a standard ethernet controller (includes some PCMCIA)). The SLIP support is rather primitive, and limited primarily to hard-wired links, such as a serial cable running between a laptop computer and another computer. The link should be hard-wired as the SLIP installation does not currently offer a dialing capability; that facility is provided with the PPP utility, which should be used in preference to SLIP whenever possible. If you are using a modem, then PPP is almost certainly your only choice. Make sure that you have your service provider's information handy as you will need to know it fairly early in the installation process. You will also need to know how to dial your ISP using the “AT commands” specific to your modem, as the PPP dialer provides only a very simple terminal emulator. If you are using PAP or CHAP, you will need to type the necessary set authname and set authkey commands before typing term. Refer to the user-ppp handbook and FAQ entries for further information. If you have problems, logging can be directed to the screen using the command set log local .... If a hard-wired connection to another FreeBSD (2.0-R or later) machine is available, you might also consider installing over a “laplink” parallel port cable. The data rate over the parallel port is much higher than what is typically possible over a serial line (up to 50kbytes/sec), thus resulting in a quicker installation. Finally, for the fastest possible network installation, an ethernet adapter is always a good choice! FreeBSD supports most common PC ethernet cards; a table of supported cards (and their required settings) is provided in the Supported Hardware list. If you are using one of the supported PCMCIA ethernet cards, also be sure that it is plugged in before the laptop is powered on! FreeBSD does not, unfortunately, currently support hot insertion of PCMCIA cards during installation. You will also need to know your IP address on the network, the netmask value for your address class, and the name of your machine. If you are installing over a PPP connection and do not have a static IP, fear not, the IP address can be dynamically assigned by your ISP. Your system administrator can tell you which values to use for your particular network setup. If you will be referring to other hosts by name rather than IP address, you will also need a name server and possibly the address of a gateway (if you are using PPP, it is your provider's IP address) to use in talking to it. If you do not know the answers to all or most of these questions, then you should really probably talk to your system administrator before trying this type of installation. Before Installing via NFS The NFS installation is fairly straight-forward. Simply copy the FreeBSD distribution files you want onto a server somewhere and then point the NFS media selection at it. If this server supports only “privileged port” (as is generally the default for Sun workstations), you will need to set this option in the Options menu before installation can proceed. If you have a poor quality ethernet card which suffers from very slow transfer rates, you may also wish to toggle the appropriate Options flag. In order for NFS installation to work, the server must support subdir mounts, e.g., if your FreeBSD 3.4 distribution directory lives on:ziggy:/usr/archive/stuff/FreeBSD, then ziggy will have to allow the direct mounting of /usr/archive/stuff/FreeBSD, not just /usr or /usr/archive/stuff. In FreeBSD's /etc/exports file, this is controlled by the . Other NFS servers may have different conventions. If you are getting “permission denied” messages from the server, then it is likely that you do not have this enabled properly. Before Installing via FTP FTP installation may be done from any FreeBSD mirror site containing a reasonably up-to-date version of FreeBSD. A full list of FTP mirrors located all over the world is provided during the install process. If you are installing from an FTP site not listed in this menu, or are having trouble getting your name server configured properly, you can also specify a URL to use by selecting the choice labeled “Other” in that menu. You can also use the IP address of a machine you wish to install from, so the following would work in the absence of a name server: ftp://165.113.121.81/pub/FreeBSD/&rel.current;-RELEASE There are two FTP installation modes you can choose from, active or passive FTP. FTP Active For all FTP transfers, use “Active” mode. This will not work through firewalls, but will often work with older FTP servers that do not support passive mode. If your connection hangs with passive mode (the default), try active! FTP Passive For all FTP transfers, use “Passive” mode. This allows the user to pass through firewalls that do not allow incoming connections on random port addresses. Active and passive modes are not the same as a “proxy” connection, where a proxy FTP server is listening and forwarding FTP requests! For a proxy FTP server, you should usually give the name of the server you really want as a part of the username, after an “@” sign. The proxy server then “fakes” the real server. For example, assuming you want to install from ftp.FreeBSD.org, using the proxy FTP server foo.bar.com, listening on port 1024. In this case, you go to the options menu, set the FTP username to ftp@ftp.FreeBSD.org, and the password to your email address. As your installation media, you specify FTP (or passive FTP, if the proxy supports it), and the URL ftp://foo.bar.com:1234/pub/FreeBSD. Since /pub/FreeBSD from ftp.FreeBSD.org is proxied under foo.bar.com, you are able to install from that machine (which will fetch the files from ftp.FreeBSD.org as your installation requests them. + + + Check your BIOS drive numbering + + If you have used features in your BIOS to renumber your disk + drives without recabling them then you should read first to ensure you do not + confused. + Installing FreeBSD Once you have completed the pre-installation step relevant to your situation, you are ready to install FreeBSD! Although you should not experience any difficulties, there is always the chance you might, no matter how slight it is. If this is the case in your situation, then you may wish to go back and re-read the relevant preparation section or sections. Perhaps you will come across something you missed the first time. If you are having hardware problems, or FreeBSD refuses to boot at all, read the Hardware Guide on the boot floppy for a list of possible solutions. The FreeBSD boot floppies contain all of the online documentation you should need to be able to navigate through an installation. If it does not, please let us know what you found to be the most confusing or most lacking. Send your comments to the &a.doc;. It is the objective of the installation program (sysinstall) to be self-documenting enough that painful “step-by-step” guides are no longer necessary. It may take us a little while to reach that objective, but nonetheless, it is still our objective :-) Meanwhile, you may also find the following “typical installation sequence” to be helpful: Boot the kern.flp floppy and when asked, remove it and insert the mfsroot.flp and hit return. After a boot sequence which can take anywhere from 30 seconds to 3 minutes, depending on your hardware, you should be presented with a menu of initial choices. If the kern.flp floppy does not boot at all or the boot hangs at some stage, read the Q&A section of the Hardware Guide on the floppy for possible causes. Press F1. You should see some basic usage instructions on the menu screen and general navigation. If you have not used this menu system before then please read this thoroughly. Select the Options item and set any special preferences you may have. Select a Novice, Custom, or Express install, depending on whether or not you would like the installation to help you through a typical installation, give you a high degree of control over each step, or simply whizz through it (using reasonable defaults when possible) as fast as possible. If you have never used FreeBSD before, the Novice installation method is most recommended. The final configuration menu choice allows you to further configure your FreeBSD installation by giving you menu-driven access to various system defaults. Some items, like networking, may be especially important if you did a CDROM, tape, or floppy install and have not yet configured your network interfaces (assuming you have any). Properly configuring such interfaces here will allow FreeBSD to come up on the network when you first reboot from the hard disk. Supported Hardware FreeBSD currently runs on a wide variety of ISA, VLB, EISA, and PCI bus based PCs, ranging from the 386SX to Pentium class machines (though the 386SX is not recommended). Support for generic IDE or ESDI drive configurations, various SCSI controllers, and network and serial cards is also provided. In order to run FreeBSD, a recommmended minimum of eight megabytes of RAM is suggested. Sixteen megabytes is the preferred amount of RAM as you may have some trouble with anything less than sixteen depending on your hardware. What follows is a list of hardware currently known to work with FreeBSD. There may be other hardware that works as well, but we have simply not received any confirmation of it.

FreeBSD currently does NOT support IBM's microchannel (MCA) bus. Troubleshooting The following section covers basic installation troubleshooting, such as common problems people have reported. There are also a few questions and answers for people wishing to dual-boot FreeBSD with MS-DOS. What to do if something goes wrong... Due to various limitations of the PC architecture, it is impossible for probing to be 100% reliable, however, there are a few things you can do if it fails. Check the supported hardware list to make sure your hardware is supported. If your hardware is supported and you still experience lock-ups or other problems, reset your computer, and when the visual kernel configuration option is given, choose it. This will allow you to go through your hardware and supply information to the system about it. The kernel on the boot disks is configured assuming that most hardware devices are in their factory default configuration in terms of IRQs, IO addresses, and DMA channels. If your hardware has been reconfigured, you will most likely need to use the configuration editor to tell FreeBSD where to find things. It is also possible that a probe for a device not present will cause a later probe for another device that is present to fail. In that case, the probes for the conflicting driver(s) should be disabled. Do not disable any drivers you will need during the installation, such as your screen (sc0). If the installation wedges or fails mysteriously after leaving the configuration editor, you have probably removed or changed something you should not have. Reboot and try again. In configuration mode, you can: List the device drivers installed in the kernel. Change device drivers for hardware that is not present in your system. Change IRQs, DRQs, and IO port addresses used by a device driver. After adjusting the kernel to match your hardware configuration, type Q to boot with the new settings. Once the installation has completed, any changes you made in the configuration mode will be permanent so you do not have to reconfigure every time you boot. It is still highly likely that you will eventually want to build a custom kernel. MS-DOS User's Questions and Answers Many users wish to install FreeBSD on PCs inhabited by MS-DOS. Here are some commonly asked questions about installing FreeBSD on such systems. Help, I have no space! Do I need to delete everything first? If your machine is already running MS-DOS and has little or no free space available for the FreeBSD installation, all hope is not lost! You may find the FIPS utility, provided in the tools directory on the FreeBSD CDROM or various FreeBSD FTP sites to be quite useful. FIPS allows you to split an existing MS-DOS partition into two pieces, preserving the original partition and allowing you to install onto the second free piece. You first defragment your MS-DOS partition using the DOS 6.XX DEFRAG utility or the Norton Disk Tools, then run FIPS. It will prompt you for the rest of the information it needs. Afterwards, you can reboot and install FreeBSD on the new free slice. See the Distributions menu for an estimate of how much free space you will need for the kind of installation you want. Can I use compressed MS-DOS filesystems from FreeBSD? No. If you are using a utility such as Stacker(tm) or DoubleSpace(tm), FreeBSD will only be able to use whatever portion of the filesystem you leave uncompressed. The rest of the filesystem will show up as one large file (the stacked/double spaced file!). Do not remove that file or you will probably regret it greatly! It is probably better to create another uncompressed primary MS-DOS partition and use this for communications between MS-DOS and FreeBSD. Can I mount my extended MS-DOS partition? Yes. DOS extended partitions are mapped in at the end of the other “slices” in FreeBSD, e.g., your D: drive might be /dev/da0s5, your E: drive, /dev/da0s6, and so on. This example assumes, of course, that your extended partition is on SCSI drive 0. For IDE drives, substitute wd for da appropriately. You otherwise mount extended partitions exactly like you would any other DOS drive, for example: &prompt.root; mount -t msdos /dev/da0s5 /dos_d + +
