Initial restructuring of the handbook's install chapter. In addition to
the structural changes, a few other things of note are:
o parts rewritten/random grammatical errors and typos fixed o Updated the 'Supported Hardware' list to equal that of the 3.4-R release notes (lots of new hardware added) and split it off into it's own section o <qandaset>-ified the MS-DOS User's Questions and Answers
