JP1: Clear CMOS Memory Jumper
This jumper lets you erase the system setup settings that are stored in
CMOS memory. You might need to erase this data if incorrect settings
are preventing your system from operating. To clear the CMOS memory,
turn off the system, disconnect the power cable from the mainboard, and
short the appropriate pins for a few seconds.

JP4: 100MHz System Bus Frequency Select Jumper
Use this 3-pin jumper to set the system bus frequency. In the normal
setting, the system automatically selects the correct frequency according
to the kind of processor installed. In the Force 100 MHz setting, the
system uses a 100 MHz system bus even if the processor is designed to
operate with a 66 MHz bus.
