I just installed CollegeLinux, which is slackware-based, on my computer. I noticed that the DVD-ROM drive wasn't working, so I went to the CL site and asked the people in yon forum at the site (college.ch/linux) how to fix yon problem. I was referred to an old conversation located at linuxquestions.org/questions/archive/8/2002/08/4/28480.

I followed the steps suggested, and found that now /mnt/dvdrom was actually using my cdrom drive, and /mnt/cdrom wasn't doing anything at all. I don't really know whether the cdrom drive worked before, because the first one I tried to use was my dvdrom drive. Any suggestions?

well firstly try to mount them directly using the ide device entries, presumably they are on /dev/hdc and /dev/hdd so for example...
and then once you are happy with with ide device goes where you can add these entries permanently to /etc/fstab, e.g.
and if you want an easier way to think about it, you can just create a symlink from the "ugly" ide entry yo your own choice...
and then you can just have a /dev/dvd entry in fstab rather than /dev/hdd etc...
