I think the only drivers needed are the AGP, LAN, and audio drivers. Of course, if you aren't running the LAN or audio chip there is no reason to enable these devices. Install the AGP driver before installing your video card drivers. I have heard some people are having slow disk performance with Win2k so if your system is affected, you may need the Win2k IDE drivers also. ocworkbench has a nice forum dedicated to ESC boards so you might want to check out the forum there. Good luck.
