be determined.
BF: Set system bus multiplier ratio
jumpers
Use this 3 x 4-pin jumper set to manually set the
system bus multiplier ratio. The CPU clock
speed is configured by the product of the system
bus frequency times the multiplier. For example,
if you have a system bus speed of 100 MHz and
a multiplier of 4, the CPU clock speed will be
100 x 4 = 400 MHz.
