What's missing here is the kernel/boot disk you are using to boot linux. In the Slackware distribution, I believe there are 2 scsi boot disks (maybe more). Check the Installation or Distribution HOWTOs to find the correct boot disk to use. I believe all the SCSI boot disks have SCSI CDROM support compiled in. If you have linux working, try recompiling a kernel with all the correct support (both for your particular SCSI controller AND for SCSI CD-ROMs). You might also check the symbolic link that is /dev/cdrom to make sure it is pointing to the /dev/scd0 (I think!) device, or just try mounting the /dev/scd0 device directly, as alluded to in an earlier response. If you haven't compiled a kernel before, get the appropriate HOWTO docs and check the readme's in /usr/src/linux. And don't have too much fun without me. Especially when you make 1 mistake configuring the kernel and get to reanswer all the questions...
