(Win2000 Info add on.) Check Toms Hardware guide on Via KX133 chipset mother boards in reguards to Windows2000. The first KX133s didn't support AGP correctly in Window2000. See Toms for details but I thought it would help to share the info. I'm buying Windows2000 my self and I just looked into my Abit KA7-100 and found it's a KX133. Oops. Time for and upgrade! :)
