After installing SP2 I went into device manager, and right clicked on the VIA BM drivers, chose update driver, chose display compatibale drivers, it found one VIA BM driver, I let it use that driver and then after wards I checked the date and it says 4/24/01. I also did the same for the Primary and secondary controller. So I guess those would be considered MS drivers. I am not sure how that whole thing works, wether or not VIA gives MS drivers to use or if MS writes there own via drivers.
