I dunno. I tried to do an XP install 7 ways to sunday and it was a no go with the geforce4 in the machine. Took it out, put a GF2 in and it installed like a champ.
If you're getting a black screen just as windows setup is ready to actually start installing, I'm betting serious money it's the card. I don't know why (timings, flakey bios, whatever), but if there's no other explanation why a bare system (vid card, mem, HDD and CD drive) doesn't install the OS until the card is replaced. In my case, Linux installed just fine on the system whereas XP would not.
I'd sure be interested in what you think it is that might be causing such behavior.
