If you're setting the CD-ROM to slave, don't forget you may have to
change the master drive from "single drive" to "master".

What are you expecting to happen?   

You do not need to configure a CD-ROM drive as you would an IDE
hard-drive.  Nor would I expect most BIOS hard-disk detection code to
detect a CD-ROM drive.

An "IDE" CD-ROM drive is nothing like an IDE disk.  It is an "AT
Atacchment Packet Interface" device, which is actually a braindead
hack for sending SCSI-like commands across an IDE bus.

OK, if Linux isn't finding it, then you do indeed have a problem.

Are you sharing a cable with another drive, or is the device the only
one on the bus?   

(Do you have ATAPI CDROM support turned on in your kernel?)

Under DOS you will have to load both a device driver and MSCDEX.EXE
before you can use the CDROM.  Have you tried that?
