As far as drivers, I'm not sure what's needed. I already had nVidea chipset drivers installed (odd experiments at a friends house with his video card) so Windows has them at it's disposal, where the BIOS doesn't.
As for AGP, I don't have a slot for that. The card is PCI. IIRC (I don't feel like looking ATM, my case is flimsier than
Arta's) I only have (had) one spare PCI slot and that's what the card is in right now, and all other cards have been in (I used an ass-old 8MB gfx card for dual-monitoring a while back as well). I'll check the BIOS stuff at the next reboot (I don't like rebooting).
