I'd check the upper limit of the clock on that motherboard - I used to run a P1/90MHz, and I know that the motherboards back then tended to be limited to clocks of 60 MHz and 66 MHz, with multipliers that allowed handling processors of no more than 2.5 times clock speed, or 166 MHz top speed. A P1/100MHz is probably running on a board with a 1.5 multiplier on a 66 MHz clock, or a 2 multiplier on a 50 MHz clock. 450 MHz may be *way* out of range for the clock to support. -- Mark L.
