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 identified 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.
