I have been having an enormous amount of trouble trying to configure this machine to work but nothing seems to work. Firstly, the motherboard has the latest bios revision, 1006, the AGP card I am using is also an ASUS card, the V3400 TNT 8MB SGRAM. I feel that there is no AGP support for NT4 from this motherboard, but would like someone to confirm this. The Asus site has miniport drivers for AGP but only for Win 95/98 no NT4. I have also tried using other video cards, such as a Diamond Viper 550 TNT 8MB and also a Diamond Stealth II G460 8MB (using intel 740 chipset) but all produce similiar problems. Does anyone have any ideas if this is something to do with NT4, the motherboard, or the graphics card ..... or even "all of the above". Any help would be appreciated, thanks.
