Explanation of
Jumpers
To modify the operation of the
motherboard, jumpers can be used
to choose between optional set-
tings. Jumpers create shorts be-
t w e e n t w o p i n s t o c h a n g e t h e
function of the connector. Pin 1 is
identified with a square solder pad
on the printed circuit board. See
the motherboard layout pages for
jumper locations.
Note: on 2-pin jumpers, "Closed"
means the jumper is on both pins
and "Open" means the jumper is
either on one pin only or com-
pletely off.
