2-7 Jumper Settings
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 identied 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.
