JP6: CPU frequency select jumper
This jumper enables you to force the CPU to clock at a higher
frequency than it is rated. Short pins 2 and 3 to force the CPU to
run at a 100 MHz FSB instead of a 66 MHz FSB. We recommend
that you leave the jumper on the normal operation setting.

JP7: CPU frequency select jumper
This jumper enables you to force the CPU to clock at a higher

run at a 133 MHz FSB instead of a 100 MHz FSB. We
recommend that you leave the jumper on the normal operation

Note:
The CPU speed is determined by the CPU Host/PCI Clock
speed multiplied by the CPU Clock Ratio. Refer to the Frequency
Control Option in Chapter 3 for more information.
Forcing the CPU to run at a higher clock speed then it was rated
for is called overclocking and is not recommended.
