Dual Pentium Pro & Asus P2B-D (Voodoo2 SLI) 

Booting a dual Pentium Pro setup on Asus P2B-D board.
Also playing Quake 3 demos with 3Dfx Voodoo 12MB SLI setup while actually using two CPUs.
Special thanks to cyreex, FLiNT1011, phantasm and max1024!
Standard Windows 2000 SP4 was used.

A video where I found out about a special multi-threaded Quake 3 build:
• Dual Pentium III Build...
That special Quake 3 patch itself (you'll need to edit config file a bit to switch it to Glide):

Original SMP MiniGL Layer (included in the patch above):

I used 7.76 drivers for GeForce2, get them here:

And I used standard Win2K Voodoo2 drivers 1.02.00, download here:

Patched BIOSes for old ASUS boards (it has the P2B-D one but it freezes during PnP init):

These are the best candidates for proper Pentium Pro patching. According to max1024's articles, all you really have to do is simply jump around code that freezes the system. Namely, NOT write a value 0xA4 to port 0xB2 (which seems to be SMI-related). Pentium Pro doesn't have some power features Pentium 2 has, and doesn't have at least one register that exists in Pentium 2, which is being written to and probably causing a freeze. Pentium Pro and Pentium 2 datasheets exist and can be found easily.
