Quick References for Jumpers
In this manual, the terms “closed” and “on” are used when referring to jumpers (or
jumper pins) that are active; “open” and “off” are used when referring to jumpers (or
jumper pins) that are inactive. See the
Figure 2-1
for examples of “on” and “off” pins
and jumpers. The square pin in the diagram is Pin 1.
Jumpers and pins are connected by slipping the blue plastic jumper connector overtop
of two adjacent jumper pins (indicated by
1-2
or
2-3
). The metal rod inside the plastic
shell bridges the gap between the two pins, completing the circuit. See
Figure 2-2
for
more example of pin connections.

The tables and maps on the following pages will help you set the jumpers for CPU speed,
Infrared, and external connector pin assignments, among others. The miniature motherboard
maps will help you locate the jumpers on your board. A full-page map of the motherboard
can be found on the next two pages.
