Can I use more than one driver on windows at the same time? I'd like to be able to switch from the offboard video card to the onboard one and vice-versa.

Out of curiosity... what is the purpose of this? – KronoS Oct 18 '10 at 15:44
Yes, by default it's 1 driver per card. Now, if you're onboard video is disabled by the PCI/AGP/PCIe video card (sometimes the case) then the disabled video card doesn't work. – Chris S Oct 18 '10 at 15:49
You should be able to switch between either of the two in the BIOS settings. – paradroid Oct 18 '10 at 16:51
@KronoS: my main video card stopped working, so i was using the onboard video from the motherboard to try to find out what was going on. – David McDavidson Oct 19 '10 at 20:18

Yes, just install both of them. When you switch between them, you can just enable and disable monitors in the display properties dialog box.
