It will work. I ...err...HAD one on a 6BA+100 up until a few weeks ago. The board went bad on me. And I could not find another one. So I got an Asus P3V4X. Not happy with it. Unstable and the PIII will only run at 1120mhz on it. It ran 1170 on the SOYO using an Alpha 3125 HS/Fans. Now I am seriously thinking about selling the P3V4X and PIII 1ghz [yes, it is the Slot 1 10x100 version,cC0 stepping]. You probably already noticed they are quite a bit more expensive than the 133mhz FSB versions cuz they quit making them.... just like the 6BA+100. Any interest in the P3V4X or PIII let me know I'll make someone a good deal on em....
