Oh Geeze! I should have played around more with BIOS settings!
There is NO setting for "route interrupus via I/O APIC" in the Tyan Tomcat's BIOS. (Is that anything like Coitus Interruptus?) :)
However, there IS a BIOS setting for the Tyan board under the "Chipset Features Setup" menu item labeled (innocuously enough):
"Chipset Special Features" Enabled/Disabled.
Setting this to "Enabled" seems to fix the problem! I hope someone puts this in the hardware FAQ for 3.0!
This was on BIOS version 4.01 for the Tomcat IIID - I had to flash the motherboard with current BIOS code. One hiccup on the flashing process - when I flashed it I got to 1F00 and the flash program locked up, but waiting 5 minutes and cold-booting the b oard seemed fine. I even flashed it twice and it locked up both times in the same location. Pretty hairy when the flash program is sitting there blinking "Do Not Cold Boot While This Program Is Running" messages.
The one noticeable difference in the mptable output after flashing the BIOS: version 4.01 of the BIOS changes the version number in the MP Floating Pointer Structure from version 1.1 to 1.4

I have seen these symptoms on my Intel Buckeyes (BB440FX). I found
that there was a setting in the BIOS for ``route interrupus via I/O
APIC'' which needed to be set for MP to work.
