Explanation of
Jumpers
To modify the operation of the
motherboard, jumpers can be used
to choose optional settings. Jump-
ers create shorts between two
pins to change the function of the
header. Pin 1 is identified with a
square solder pad on the printed
circuit board. See the mother-
board layout pages for jumper lo-
cations.
