Well, I couldn't find a way to change any of these settings in the
BIOS, as the drive was set to "autodetect". Then I changed it to be
"CDROM", and that did change some settings (like disable DMA), but
didn't fix the problem. Lastly, I downloaded the latest BIOS for my
motherboard (an Intel Desktop Board D850GB), and that seems to have
fixed the problem, as I didn't change any other settings.

But I do have a master drive on that channel. Like I mentioned
before, there are two hard disks in /dev/hd{a,c}, and the CD-ROM is /
dev/hdb (like I suspected).
Anyway, thanks for everyone's help. I am up and running with a CD-
ROM drive again.
