Duh. Re read what you wrote. If you put a 133 bus CPU on a 100 bus board
it'll just run slower. Same multiplier at lower bus speed.
The catch is there were multiple varieties of the 1.0 GHz p3 with different
voltages so just make sure you're using a .25 micron pentium 3 and the
voltages should be close enough. .18 micron p3s (I forget if they ever
came as slot 1 but adapters exist ) or "Tualatin" p3s run at a lower
voltage and have some other minor adjustments to the socket.
