 If you read no other documentation before installing this
 version of FreeBSD, you should at least by all means *READ
 THE ERRATA* for this release so that you don't stumble over
 problems which have already been found and fixed.  This ERRATA.TXT
 file is obviously already out of date by definition, but other
 copies are kept updated on the net and should be consulted as
 the "current errata" for your release.  These other copies of
 the errata are located at: 
 
   1. http://www.FreeBSD.org/releases/
 
   2. ftp://ftp.FreeBSD.org/pub/FreeBSD/releases/<your-release>/ERRATA.TXT   
      (and any sites which keep up-to-date mirrors of this location).          
 
 Any changes to this file are also automatically emailed to:
 
 	freebsd-current@FreeBSD.org
 
 For all FreeBSD security advisories, see:

 ---- System Update Information:
 
+The FreeBSD Boot Manager (boot0) has a bug that causes it to hang the machine
+during boot with no screen output.
+
+Fix: Boot your machine into FreeBSD either via a boot floppy or a CD-ROM, then
+download a new boot0 binary from the following location:
+
+	http://people.FreeBSD.org/~jhb/4.1R/i386/boot0
+
+Once you have downloaded the new binary, install it with the boot0cfg command
+onto your hard disk.  For example, if you have boot0 on disk ad0, you would
+run the following command:
+
+	/usr/sbin/boot0cfg -B -b /path/to/downloaded/boot0 ad0
+
+You may also use cvsup to update your source tree and build the new boot0
+binary from source.  You will need version 1.14.2.3 of
+src/sys/boot/i386/boot0/boot0.s or newer.
+
+The MD5 checksum of this file is:
+
+	MD5 (boot0) = 8770a386dba44f0aa06b15db72c1f624
+
+To verify the checksum of your downloaded copy, perform the following
+command:
+
+	/sbin/md5 /path/to/downloaded/boot0
+
+and compare with the above.
