Ok, wait a minute, this is from www.bp6.com:

The main issues of why the PIII is not natively supported on the BP6.
1. Pin layout is different (PPGA vs. FC-PGA)
2. Voltage differences (Vcore, VTT, etc.)
3. Voltage stability on the BP6
4. BIOS Microcode (no PIII support in the OEM BIOS)

So maybe the PIII is not compatible on this board...
