Is it a PCI card or integrated adapter on motherboard?
If onboard motherboard, what make / model is the motherboard?
Here's the link to the viaarena driver download, but if onboard my first port of call would be MB manufacture website.

Unsure of this one. If it's an onboard card, is it disabled within BIOS.
Got a funny feeling windows won't see it at all if that was the case, but might be worth checking anyway.
