If memory serves correctly, the boards that used the AMD northbridge and Via Southbridge (such as yoursand my own, the Epox 8k7a) require the Via drivers for the south bridge fuctions, such as IDE and USB. You'll need to download the AMD drivers for the AGP drivers, but I think the ones that come with windows XP should be fine. (AMD hasn't updated their drivers in a while) Just download the Via Hyperion 4-in-1 drivers and it will install whatever is necessary.
