5-10 Jumper Settings

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: On a two-pin jumper, "Closed"

means the jumper is on both pins and

"Open" means the jumper is either on

only one pin or completely removed.

With the power disconnected, short the CMOS pads with a metal object such 2.

as a small screwdriver.
