Front Side Bus Speed
JP1 and JP2 are used to set the
system (front side) bus speed for
the processors. It is best to keep
these jumpers set to Auto. This
jumper is used together with the
CPU Clock setting in BIOS. See the
table on the right for jumper set-
tings.
5-10 Jumper Settings
Explanation of
Jumpers
To modify the operation of the moth-
erboard, jumpers can be used to
choose between optional settings.
Jumpers create shorts between two
pins to change the function of the
connector. Pin 1 is identified with a
square solder pad on the printed cir-
cuit board. See the motherboard
layout pages for jumper locations.
Note: On a two-pin jumper, "Closed"
means the jumper is on both pins
and "Open" means the jumper is ei-
ther on only one pin or completely
removed.

CMOS Clear
JBT1 is used to clear CMOS (which will also clear any passwords). Instead of
pins, this jumper consists of contact pads to prevent accidentally clearing the
contents of CMOS.
To clear CMOS, 1) First unplug the power cord(s) 2) With the power disconnected,
short the CMOS pads with a metal object such as a small screwdriver 3) Remove
the screwdriver (or shorting device) 4) Reconnect the power cord(s) and power on the
system.
Note: Do not use the PW_ON connector to clear CMOS.
