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. Recon-
nect 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.

Note: Before clearing the BIOS, ensure that AC power is not con-
nected.
JP6: CPU frequency select jumper
This jumper enables you to force the CPU to clock at a higher fre-
quency 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.
Function Jumper Setting
Normal Short pins 1-2
Force 66 MHz FSB to
run at 100 MHz FSB. Short pins 2-3

JP7: 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 133 MHz FSB instead of a 100 MHz FSB. We recom-
mend that you leave the jumper on the normal operation setting.
Function Jumper Setting
Normal Short pins 1-2
Force 100 MHz FSB to
run at 133 MHz FSB Short pins 2-3

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.
JP8: BIOS Flash protect jumper
Use this jumper to enable or disable the BIOS flash protection
on the mainboard. You should disable this jumper when you
want to flash the BIOS.
Function Jumper Setting
Disable Short pins 1-2
Enable Short pins 2-3
