[OpenBIOS] BINGO!

Procedure:
1) Load Intel L440GX Standard BIOS
2) Switch the BIOS recovery jumper on (while system is running)
3) Get to the LILO prompt and reboot processor 0 (leave proc 1 running!)
4) Load LinuxBIOS SMP kernel
5) Switch the BIOS recovery jumper off (while system is running)
6) Reboot processor 1
7) Get Linux to 0010:00100000 and set BX to 0x0 (workaround -- this should
be in LinuxBIOS).
8) Run hit F5 and look at the (framebuffer's) penguins!!! (For the ACL
guys, check out the VA slate on my workbench.)
Ron: We are good to go!! It is pretty obvious to me that processor 2
needs to run the MTRR init code; how do you want to do this? Perhaps an
#ifdef LINUXBIOS in the kernel, or do you want to do a startup IPI?
{Free,Open}BIOS lists: Does anyone know why we have to set BX to 0x0? Does
anyone know why we get 'unexpected IRQ trap at vector 31.' when we
calibrate the delay loops (on both processors)?
Cheers.
