Bump for after vacation. I bought my dad an HP dual processor machine that came with Vista. He never could make friends with Vista, gave the computer back to me and went back to his old machine. When I get back home and get it set up and working, I’ll see if it can be persuaded to work all night on this project.
SMP on Vista is a pain, but there is a Wiki on the subject here:

It requires you to pay attention, but takes about 15 minutes.
You could always call HP and badger them into providing a copy of XP. Sometimes HP will do that.
