After upgrading to the latest BIOS , all the video cards I have, but one, worked properly. These include a Matrox Millenium PCI, Diamond Viper V5500 AGP, Matrox Mystique G200, Real3D Starfighter AGP, and the Diamond Monster Fusion AGP, with the card giving problems being the Diamond Stealth II G460, a dreaded i740 card. It worked OK, except it would freeze the system within a few hours of use. The Monster Fusion had the most problems until upgrading to the latest BIOS, which fixed all the problems. The board was so stable, that twice I have gone for over a week without rebooting.
Crashes are very rare.
I tested the 100 MHz FSB setting with my K6-2 300. Of course, this may not hold true for you, but it worked for me. I did have another problem with the board. I used to have two internal PCI modems in my AOpen AX5T-3. However, with the Epox, I was unable to load Win98 unless I pulled one of them because of a conflict with the COM1 mouse.
