Device drivers that aren't in the OS package either come from the addon card's manuf. (VIA?) or ASUS. It's possible but unlikely that you'll be successful w/MS.
If you aren't successful at one of those places then you are up a creek.
I already contact ASUS and basically all they have to say is that the Motherboard is to OLD, it is my fault for not making sure it was compatible and they will not do anything about it, not even a trade in for a new one.
Needless to say that was the last ASUS motherboard I ever buy. If anyone cares to buy it will sell it for cheap or trade for some parts.
