Requirements to support Pentium-MMX processors:
FSB - 66MHz (any board supporting Pentium-100 has it)
Multiplier - 2.5 for 166MHz, 3 for 200MHz, 3.5 for 233MHz (but you can use a 1.5 mult, and the processor will interpret it as 3.5)
voltage - split voltage: 3.3V out, 2.8V core. If your board can't support that, you're out of luck.
If you have the right voltage, you may want to consider some AMD K6 instead - I understand some older boards support the 400MHz (mult of 6, but you set the board as 2)
