Hey, don't give an answer if you don't know. He will end up wasting $$$ thinking that a celery600 will work with bp6. It will not work. Not without a third-party adapter (powerleap) or some serious modding. Also, celeron 600 is not smp-compatible. It doesn't matter 'cause it just won't work. The fastest celeron that will work w/o any modding is 533 (original ppga version) which is also smp-capable.
