Thanks to everyone.
Problem solved.
Yes, I misunderstood "fdisk -l". I assumed that it would list
the CD partition also.
I never even tried to mount the CD, as I thought that when
it was not being seen by fdisk, it was not there, and there was nothing to mount.
Also I've learned how to install from another version of debian,
although it appears that this is not recommended.
So, mount /media/cdrom0 worked perfectly,
and after installing hal, I could see the CD icon on the desktop.
Thanks again.
John
