I just recently learned a lot about this subject. I was testing a DUAL
and put a lab machine's (a single p100) guts into it. Without doing
else, I was able to boot it as a single processor p166. Now the system
parition is a FAT Patition (which later turned out to save my rear).

You have to replace the ntoskrnl.exe and hal.dll files with the
files of your SMP motherboard. For mine, this was ntkrnlmp.exe and
halmps.exe. Once I got these files copied to the previous names, the
second processor came right up. I was booted to DOS when I did this.
The uptomp.exe file that comes with the resource kit does this same
thing, just behind you back.
