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.
Note: On two-pin jumpers, "Closed" means the jumper is on, and
"Open" means the jumper is off the pins.
