Quick Jumper Setting Reference
JP1: Clear CMOS jumper
Use this jumper to clear the contents of the CMOS memory. You
may need to clear the CMOS memory if the settings in the BIOS
Setup Utility are incorrect and are preventing your mainboard
from operating. To clear the CMOS memory, disconnect all the
power cables from the mainboard and then move the jumper cap
into the Clear CMOS memory setting for a few seconds. CMOS
is cleared.
Return the jumper cap to the Normal operation setting.
Reconnect the power cables and start the system. When the
POST starts, press the delete key to start the BIOS Setup Utility
and reload BIOS optimal settings. Refer to Chapter 3 for
information on BIOS.

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.
