I forgot to mention that I also tried booting my machine from the
Fedora 8 Live DVD, and the system came up just fine. This shows
that the hardware is okay.

[top-posting corrected]

Maybe the working machine has a daemon that creates a dir and mounts the cd
automagically. A daemon which is not running on the problem machine. I also
don't have an entry /mnt/cdrom in fstab - everything on my Gentoo system is
done by HAL/udev and KDE's service for removable media.

Windows is great - you can download Linux with it.

As root type this:

mkdir /media
mkdir /media/cdrom
mount /dev/cdrom /media/cdrom

It's not that simple. Linux has daemons that check for new
hardware and create directories like /media/cdrom as needed.
/media/cdrom depends on there being one or two other directories
in /dev, which have to be configured correctly for anything at all
to be mounted.

I did try what you have above, which resulted
in the message:

mount: /dev/cdrom is not a block device

I had a similar problem and followd your directions:

mkdir /media
mkdir /media/cdrom
mount /dev/cdrom /media/cdrom

And it worked for me. I'm running SLES10SP2. Why would I be missing the /media/cdrom directory?
