Does anyone know how I can load Linux onto a Toshiba Prestege 300CT??
I created a copy of the bost disks from the web site (along with the
base files on disk) yet I cannot get Linux to start.  Everytime I try
to boot, the computer restarts.  I tried the other Toshiba boot files
and got the same problem.

Is that a laptop?  If so you should take a look at the Linux
Laptop homepage to find out if Linux runs on your machine and
if it needs some modifications.
