Explanation of
Jumpers
To modify the operation of the
motherboard, jumpers can be used
to choose between optional set-
tings. Jumpers create shorts be-
t w e e n t w o p i n s t o c h a n g e t h e
function of the connector. Pin 1 is
identified with a square solder pad
on the printed circuit board. See
the motherboard layout pages for
jumper locations.
Note: on 2-pin jumpers, "Closed"
means the jumper is on both pins
and "Open" means the jumper is
either on one pin only or com-
pletely off.

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 acciden-
tally 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.
