Pre-Installation Procedure

Before you install your motherboard into a chassis, it's convenient to install the CPU,
install the memory modules, and set all the jumpers to correct settings.
Jumpers Setting Explain
This motherboard has jumpers that need to be set correctly. You can use a jumper
cap to connect two adjacent pins. When a jumper cap connects two pins, we say
that the pin are SHORT. If you remove a jumper cap from two pins (or placed on just
a single pin), we say that the pin are OPEN. The examples and illustrations below
show the different positions of a jumper cap on the typical 3-Pin jumper. By changing
the jumper cap, you change the circuit of the motherboard and enable or disable
certain feature or properties of the board.
