2-6 Jumper Settings
Explanation of
Jumpers
To modify the operation of the
motherboard, 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 identifi ed with a
square solder pad on the printed circuit
board. See the motherboard layout
pages for jumper locations.
Note: On two pin jumpers, "Closed"
means the jumper is on and "Open"
means the jumper is off the pins.
