Good point. However, under the original BIOS, I couldn't use the 100MHz
bus speed, so I was *under-clocking* my PII/400 (it was running at 266,
ie. 66MHz bus speed x 4 instead of 100Mhz b/s x 4) until I flashed the
BIOS. So yes, you *could* use the 66MHz RAM, and it *would* slow down
the machine, but it's pretty damn pointless buying a 100Mhz bus CPU.
Might as well get a Celery... 8)
