So you cant mount the cd although when you cat /etc/fstab you see it listed?

Tried to mount / umount with no success?

Well, this worked for me:

cd into the /dev directory and look for the name of the device thats listed in fstab. In my case it was acd0 (ZERO). In the /dev directory there was a acd0a and acd0b.

I entered this:

mount -t cd9660 /dev/acd0a /cdrom


cd /cdrom

Good luck.
