Explanation of Jumpers
To modify the operation of the mother- board, 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:Ontwopinjumpers,"Closed" means the jumper is on and "Open" means the jumper is off the pins.
