I recently experimented a bit with adding a second entry to autoexec.bat
and config.sys to add DOS support for a second CD-ROM device, (my
recorder). No luck, though, although I gave up perhaps too easily.
Here's what I did:

config.sys includes:
DEVICEHIGH=C:\DEV\TSYCDROM.SYS /D:IDECD_00 /P:SM
DEVICEHIGH=C:\DEV\TSYCDROM.SYS /D:IDECD_01 /P:SM

autoexec.bat includes:
LH C:\WINDOWS\COMMAND\MSCDEX /D:IDECD_00 /L:L
LH C:\WINDOWS\COMMAND\MSCDEX /D:IDECD_01 /L:M

This may have something to do with the fact that my system is SCSI based (but
the general procedure is the same), but I have a Panasonic 4x8 CD-R device
and Plextor 12/20Plex CDROM drive on the SCSI bus. I load ONE CDROM driver
(aspicd.sys) in config.sys and ONE MSCDEX.EXE in autoexec.bat, and it
recognizes BOTH drives and assigns them consecutive drive letters (E: and F:).

While the CD driver (aspicd.sys) is specific to SCSI, the MSCDEX is the same
that comes with DOS. So, it looks like they can handle more than one device
with just the one instance of the driver.

If you have difficulty recognizing both drives, then perhaps one isn't
working or is cabled or jumpered wrong.
