Jumper Settings
Jumpers
Several hardware setting are made through the use of jumper caps to
connect jumper pins (Jxx) on the mainboard. See " Map of the
mainboard" for locations of jumpers.
The jumper settings will be described numerically such as [----], [1-
2], [2-3] for no connection, connect pins 1 & 2, and connect pins 2
& 3 respectively. Pin 1 for our mainboard is always on top one or
on the left when holding the mainboard with the keyboard away from
yourself. "P1" is written besides pin 1 on jumper with three pins.
The jumpers will also be shown graphically such as
to connect
pin 1&2 and
to connect 2&3. Jumpers with two pins will be
shown as
for Short (on )and
for Open (off).For manufac-
turing simplicity it may be sharing pins from other groups. Use the
diagrams in this manual instead of following the pin layout on the
board. Settings with two jumper numbers require that both jumpers
be moved together. To connect the pin, simply place a plastic jumper
cap over the two pins as diagrammed.
