SiS made the 961 chipset, not Gigabyte. Did this device come pre-installed in your computer at the time of purchase or did you purchase it separately then add it to the pc?
What is the interface? ie: the choices are:
1: Integrated on the motherboard via a chipset?
2: A PCI or AGP card?
Used in a laptop or desktop computer?
Computer/motherboard brand and model?
Did it come from the factory with Windows XP installed?
