It is running off a CD disk that I burned the 32-bit Ubuntu server
install on (Ubuntu server, not desktop). The CD has a 700 MB capacity
and runs at a max of 52x speed. It is running in the optical disk drive
part of the machine. I assume the drive also accepts CD's in addtion to
DVD's. I'll check with a Geek I have an appointment with to see this
morning to make sure there is no problem running the CD in this optical
drive. Does this help target the problem any?
