Connectors & Jumpers

This chapter provides the layout, descriptions and functions of
the connectors and jumpers of your motherboard.

There are a number of connectors and jumpers on the
motherboard. Connectors allow you to connect to different
peripherals and/or devices. Jumpers, on the other hand,
provide you flexibility and different functions when set to different
values.

These jumpers were set to factory default before shipping,
which gives you the best performance. You should not alter
these settings unless you are sure of what you are doing. If you
want to change any setting, please make sure that the computer
has been turned OFF and make a note of what the original
settings are. This way, you can always revert to the original
settings if the new settings do not work.
