When I restart my computer in DOS mode, it doesn't recognize  my CD-ROM drive. Why not?  More importantly, how do I remedy this?  Does WIN95 DOS mode use config.sys or autoexec.bat?  Any help will be greatly appreciated.

 For your CD-ROM to work in DOS mode there must be
CD-ROM driver loaded in config.sys and mscdex.exe
loaded in autoexec.bat. These drivers are not needed for normal
win95 operation and are often removed by win95 setup,
but leaving them is harmless. If there is a line in your autoexec.bat starting with REM which contains MSCDEX,
uncommenting it may be sufficient.
  Also look at your CD-ROM docs or disk that came with it,
there should be instructions on how to set up drivers
for MS-DOS (or MS-DOS mode), because drivers are
different for various CD-ROM models.
  As for autoexec and config for MS-DOS mode, yes, they
are the same autoexec.bat and config.sys which are used
by win95. But when you switch to the "previous version of
MS-DOS", (you can do this only if you keep it during win95 setup), autoexec.dos and config.dos are used, and their win95 counterparts are renamed to .w40.

There is a file called dosstart.bat in the windows directory.
You can modify the file to load the MSCDEX driver when windows
exits.  I would put the device driver in the config.sys file for
loading on system start.  Another thing you can do with
dosstart.bat is modify it to use the choice command so that you
have a choice on whether you want to load mscdex or not.  Because
if you don't want to, and it loads, then when you type exit to
restart windows, it will reboot.  Also, if you want it to load mscdex when the computer starts for some reason, then just stick it in autoexec.bat.  For instance, if you wanted to load it because you pressed F8 and selected MSDOS command prompt only, then you would use autoexec.bat.  And here again, you can use choice command incase you don't want it loaded.  For either of the two commands just type command /?.  For the Device driver look in your CDROM manual or on the Web for info.
