Is the CD-ROM drive listed in the drive table shown after the BIOS POST?
If not, the system isn't recognizing the drive so nothing thereafter can
access it.
Does your BIOS have settings to affect boot drive order? If so, does it
include the CD-ROM drive? If so, set the boot drive order to A:
(floppy), CD-ROM, and then hard drive, then boot WITHOUT a floppy but
with a bootable CD in the CD-ROM drive, like your Windows 2000/XP
install CD. Does it start the Windows setup (you might have to hit a
key if the BIOS prompts to hit one to boot from the CD-ROM instead of
skipping it)? By checking that your BIOS is configured to boot from the
CD-ROM drive and seeing if it does then all the errors in using a floppy
with CD-ROM drivers and an OS loading support for it are eliminated
because none of that got used to boot from the CD-ROM drive.
You never mentioned whether or not this CD-ROM ever worked before in
your computer. Did it work before and then stop working? Did it ever
work?
Have you always set it up on its own cable with no other drives (thus on
its own IDE port, too)? Did you attach to the END of the ribbon cable?
Did you check that the ribbon cable wasn't reversed (i.e., backwards) on
either end? Check if the marked side (usually a red stripe) is
connected to pin 1 on both the motherboard header and on the CD-ROM
drive. For "normal" ribbon cables, it doesn't matter if the cable is
switched on both ends because the signal wires still match up so you are
looking for just one end to be reversed. However, there are some ribbon
cables that have a small piece of a signal wire removed (pin 34, I
think) which will not work if the entire ribbon cable (i.e., on both
ends) is reversed. So make sure pin of the ribbon cable matches pin 1
of the header/connector on BOTH ends.
Make sure your BIOS has the IDE port enabled for whichever one you are
using to connect the CD-ROM drive. If it weren't enabled, you wouldn't
see the CD-ROM drive listed in the BIOS POST table of detected drives.
