explain how to install the support software that
comes on the Support Disk. If the board is already
installed in a system, you may want to review this
chapter or you can skip it and go to the next chap-
ter which covers some post-installation topics.
Hardware Configuration
There are three steps to configure the mother-
board hardware before installing it in a system
housing: configuring the jumper switches, in-
stalling a CPU and installing system memory.
Configuring The Jumpers
This motherboard has four jumper switches. All
the jumpers come preset to default settings. You
may not need to change any of the settings. Please
note that once the motherboard is installed, you
should always turn your computer off and disco n-
nect the power cord before changing any jumper
settings. In all cases, you should always take pre-
cautions against static electric damage to sensitive
components. The default settings are listed in the
following table.
