In order for a CD-ROM to run in DOS mode, there needs to be one type of
statement in the config.sys, and another type of statement in the autoexec.bat
(or dosstart.bat, which we'll get to in a minute).

Your blank config.sys needs a statement like this:

DEVICE=C:\CPQDOS\CPQIDECD.SYS / D:IDECDOO1

But in order for that statement to have any meaning, you must have a directory
named CPQDOS on your C drive, and a file called CPQIDECD.SYS in it.  It sounds
like you can copy both of them (directory and file) from your (now) D drive to
your (now) C drive.

Then, you have to deal with your autoexec.bat (or your dosstart.bat).  In it,
you need a statement like:

C:\Windows\Command\MSCDEX.EXE /L:L /D:IDECD001

You don't have to put any files anywhere, because this statement refers to a
file that definitely already exists in the c:\windows\command\ folder.

The question you need to answer is: Under what circumstances do you want your
CD-ROM to work in DOS?  CD-ROM's work better in Windows 95 if they do NOT have
the DOS drivers loaded, which means you don't want that statement in your
autoexec.bat.  But, if you have need to boot into DOS frequently at system
startup (and why, by the way?), then you would create a statement in your
autoexec.bat exactly like I have it above.

But, if you just want to access your CD-ROM in DOS mode from time to time, then
the same statement would go into a file called "dosstart.bat", instead.
 Dosstart.bat is a file that is run when you shutdown Windows 95 and choose
"Restart In DOS mode".

And, by the way, the only way your CD-ROM is going to be drive "L" in DOS mode
is if your autoexec.bat (or dosstart.bat) statement contains the switch:
   /L:L    as I have it written above.
