Quote from gnome:
You need to tell the board what video card you have... any low profile card will be OK so long as it's compatible with your other.
If you're using the onboard video now, you'll have to look inside and tell the board what kind of "slot" you have... probably PCIE or AGP, if any.
I'm not at home right now but I'm pretty sure it's a 128MB ATI x600 card. I'll have to double-check later tonight. Thanks.
