2-7 Jumper Settings
Explanation of Jumpers
To modify the operation of the mother-
board, jumpers can be used to choose
between optional settings. Jumpers cre-
ate 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:
On two pin jumpers,
"Closed" means the jumper
is on and "Open" means the
jumper is off the pins.
