connect jumper pins on the main board. The jumper's pin 1 on main board
will be on the top or on the left when holding the main board with the
keyboard connector away from yourself. Pinout numeric is written around
the jumpers with
four or six pin jumpers. The jumpers will be show
graphically such as
to connect pins 3&4 and 5&6, and
to connect pins 1&2 and 3&4 for six pin jumpers.
Jumpers will be show graphically such as to connect pins 2&4 and
to connect pins 3&4 for four pin jumpers.
Jumpers with two pins will be shown as for Short (On) and for
Open (Off).
To connect the pins, simply place a plastic jumper cap over the two pins as
diagramed.
