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.
