Well, here the problem *seems* simple: you just forgot to mount your CD unit with
mount -t iso9660 /dev/hdh /mnt/cdrom
That's why Linux can't find the filesystem there... Also (I think) you should only do
a ls to a mounted filesystem... Other possible reason is that the device in /dev/hdh
hasn't been created yet... for that purpose (I guess) you'd have to use MAKEDEV, but
then it's a bit beyond my present knowledge...
As for reasons why the device doesn't show up when you hard boot into Linux... have
you tried plugging the CD-ROM cable straight into the IDE card? This might even solve
the previous problem, and the CD unit should be recognized as /dev/hdb, hdc or hdd
(if it's plugged as 1st slave, 2nd master or 2nd slave, respectively). For the
messages you sent I'm almost sure it is a REAL ATAPI/IDE CD-ROM drive.
Hope this helps!
