You didn’t try reflashing the BIOS?
No. The machine served ably as my Fedora host until I retired it last year in favor of a quad core Intel machine. It is now running 64-bit Fedora 11. I configured that machine for the purpose of doing functional programming on a multi-core machine (erlang/scala). Unfortunately, my little fire breather is in Pocatello. I'm in San Diego. I'll have it running next week when I go home for Christmas.
