Might search the archives. IIRC, one poster the other day discovered
that on his particular MB, the presence of a USB header jumper caused a
problem. Probably not your situation, but the archives might inspire
some ideas. Also, strip the machine of *everything* you can and start
install and see how it goes. Turn off everything in the bios that you
can. If you get a good install, enable stuff one-by-one.

Google for your MoBo and either Fedora or CentOS 4 and maybe their are
clues there. Tech support for the MoBo may have the answer already too.
Check their forums.
