Explanation of
Jumpers
To modify the operation of the
motherboard, jumpers can be used
to choose between optional set-
tings. Jumpers create shorts be-

identified with a square solder pad
on the printed circuit board. See
the motherboard layout pages for
jumper locations.

CMOS Clear
JBT1 is used to clear CMOS (which will also clear any passwords). In-
stead of pins, this jumper consists of contact pads to prevent accidentally
clearing the contents of CMOS. To clear CMOS,
1) First power down the system and 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.
