Actually, you can run ANY part which the Pentium supports an appropriate bus fraction, even if the board does not. You can just jumper the board to do the frequency you want, and you can force the CPU to choose a bus fraction by modifying your own socket. I know it's a pain, but people waste all kinds of time trying to fry their CPU by running it over the rated clock frequency anyway :) At boot, the CPU looks to see how it's jumpered (no, I don't know the pins offhand), and the PLL reacts accordingly. For example: It would be possible to run 133/66 or 180/60 as well as 120/60. -Clint
