Hardware Setup
If your mainboard has already been installed in your computer you may still need
to refer to this chapter if you plan to upgrade your system's hardware.
Be sure to disconnect the power cable from the power source before
performing any work on your mainboard, i. e. installing a CPU, memory
module, changing a jumper setting, adding or removing expansion cards
etc. Not doing so may result in electrical shock or severe damage to your
mainboard and peripherals!
2-1 Introduction to Jumpers
Jumpers are used to select between various operating modes. A jumper consists
of a row of gold colored pins that protrude from the surface of the mainboard. It
is important not to confuse jumpers with connectors or headers.
Putting jumper caps on anything that is not a jumper may result in
damaging your mainboard. Please refer to Section 1-3, Mainboard
Layout, for the location of jumpers on your mainboard.
As indicated in Figure 2-1 below, a cap is used to cover the pins of a jumper, resulting
in shorting those pins that it covers. If the cap is removed from the top of the pins,
the jumper is left "open." The number 1 shown both in the diagram below and in
all multiple pin jumper and header diagrams in this manual indicates the pin designated
with the number 1. The numbering of the remaining pins follows in sequence.
