This info is for a 2.4 kernel. I haven't played with a 2.2 kernel in a while so
I don't know if this is accurate for that series.
cat /proc/scsi/scsi
cat /proc/sys/dev/cdrom/info
This will tell you what your drive is.
/dev/cdrom is probably still pointing at /dev/hdc. You will need to remove the
link and create another to the device name you got from
/proc/sys/dev/cdrom/info i.e. drive name: sr0 in my case.
If you don't get any info then you need to look for two modules, ide-scsi and
sg. Both are required for scsi emulation. If you didn't setup scsi emulation by
appending hdc=ide-scsi to lilo; if you install ide-scsi and then sg modules, it
will map your ide cdrom to a scsi /dev/whatever. You don't have to reboot. The
append in Lilo and reboot is so you have the scsi emulation at boot and don't
have to manually load modules. I like to know about loading and unloading sg
because I have had CDRWs that were a little flaky. I buy cheap.
I like this shell script because I don't have to remember the directories in
/proc.
