Explanation of Jumpers

To modify the operation of the motherboard,

jumpers can be used to choose between

optional settings. Jumpers create shorts be-

tween two pins to change the function of the

connector. Pin 1 is identiﬁ ed 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.
