Explanation of
Jumpers
To modi f y the operat ion 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.
