FYI:
On the BP6 (GREAT BOARD!) you MUST put Pentium 3's in it to run SMP-no Celeron after the original PPGA Celerons will do SMP. Also, last I heard, the BP6 had trouble with the power requirements of dual P3's (but one is supposed to work fine) and would be unstable, but let us know if you have good luck with it.
