2.3 Setting 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.
Quick References for Jumpers
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.
