5-9 Jumper Settings
Explanation of Jumpers
To modify the operation of the mother-
board, jumpers can be used to choose
between optional settings. Jumpers cre-
ate shorts between two pins to change
the function of the connector. Pin 1 is
identifi ed with a square solder pad on
the printed circuit board. See the mother-
board 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 either on
only one pin or completely removed.

CMOS Clear
JBT1 is used to clear the saved system setup confi guration stored in the CMOS
chip for node 1, while JBT2 is used for node 2.
To clear CMOS,
1. First power down the system and unplug the power cord(s). It is also recom-
mended that you remove the onboard battery from the motherboard.
2. With the power disconnected, momentarily short the CMOS pads with a metal
object such as a small screwdriver. Remove the screwdriver (or shorting
device).
3. Reconnect the power cord(s) and onboard battery and power on the system.
Note: Do not use the PW_ON connector to clear CMOS.
