Welcome to the overclockers.com forums!
I used to have a BH6 rev 1.01 board and I started off with a SEPP Cellie 433 and ended up with a P3 1000E cD0 flip chip on an Abit Slotket3. In between, I ran a cB0 P3 750E flip chip on the slotket and a cC0 P3 1000E slot1 server proc on it. Even though Abit says that the board doesn't support the coppermine procs, I never had a lick of problems running them. Basically you can use any coppermine P3 or Celeron up to 1100 that run on a 100 mhz fsb and the SS bios revision. Hope this helps you out.
BTW, you would probably get a faster response if you had posted this in the Intel Motherboards section.
