Jumpers are small blocks on a system board with two or more pins
emerging from them. Plastic plugs containing a wire fit down over the pins. The wire
connects the pins and creates a circuit.
To change a jumper setting, pull the plug off its pin(s) and
carefully fit it down onto the pin(s) indicated.
NOTICE: Make sure that your system is turned off and
unplugged before you change a jumper setting. Otherwise, damage to your system or
unpredictable results may occur.
