CPU Frequency
Systems designated as 150 MHz use the 60 MHz P6 bus, with jumpers
installed to obtain the 5/2x multiplier. Systems designated as 180 MHz use
the 60 MHz P6 bus, with jumpers installed to obtain the 3x multiplier.
Systems designated as 200 MHz use the 66.67 MHz P6 bus, with jumpers
installed to obtain the 3x multiplier.
The following tables show how each multiplier is achieved. IN denotes the
jumper is installed on both connector pins.
