2-4 System Configuration
The following sections provide information and guidelines about the jumpers
and their factory settings.
Note:
Jumpers are set correctly at the factory for the
system configuration. If a jumper change is required, change
only the setting for that condition.
System Board Configuration Settings
System board jumpers enable you to configure your system for a particular
system requirement.
You may need to change the system board settings to:
„
configure the system for a graphics board by disabling the onboard VGA
„
restore the CMOS settings to their factory state
„
prepare the system for the installation of a slower processor
„
configure the system to power on when the power cable is plugged in
instead of when the power button is pushed.
!
CAUTION
Jumpers are set correctly at the factory for your
configuration.
If your system requires a jumper change, change only the
setting for that condition. Otherwise, keep the jumpers at
their factory settings.
The following figure shows jumper locations on the system board.
