2.5 Jumper Settings for the CPUs Front Side Bus
Jumpers JP2 and JP3
CPUs Front Side Bus Select
The default setting of jumpers JP2
and JP3 is Auto - the system will
automatically run according to the
FSB of the processor.
Warning:
Overclocking a 66MHz FSB processor to 100MHz or
133MHz will provide better system performance. However, not
all 66MHz FSB processors are capable of running at 100MHz
or 133MHz bus speed. Therefore, if you are unable to boot
your system when set at 100MHz or 133MHz, make sure to
set JP2 and JP3 back to their default setting.
