2. Hardware Setup

In this chapter we will elaborate all the information you need upon installing this motherboard
to your computer system.

※ Always power off the computer and unplug the AC power cord before adding or

removing any peripheral or component. Failing to do so may cause severe
damage to your motherboard and/or peripherals. Plug in the AC power cord only
after you have carefully checked everything.

2.1 Choosing a Computer Chassis

• This motherboard carries a mATX form factor of 244 x 244 mm. Choose a chassis big
enough to install this motherboard.

• As some features for this motherboard are implemented by cabling connectors on the
motherboard to indicators and switches or buttons on the chassis, make sure your chassis
supports all the features required.

• If there is possibility of adopting some more hard drives, make sure your chassis has
sufficient power and space for them.

• Most chassis have alternatives for I/O shield located at the rear panel. Make sure the I/O
shield of the chassis matches the I/O port configuration of this motherboard. You can find
an I/O shield specifically designed for this motherboard in its package.

2.2 Installing Motherboard

Hardware Setup

Most computer chassis have a base with
many mounting holes to allow the
motherboard to be securely attached, and at
the same time, prevent the system from
short circuits. There are two ways to attach
the motherboard to the chassis base:

1. use studs, or

2. use spacers

In principle, the best way to attach the board
is to use studs. Only if you are unable to do
this should you attach the board with spacers.
Line up the holes on the board with the mounting holes on the chassis. If the holes line up and
there are screw holes, you can attach the board with studs. If the holes line up and there are
only slots, you can only attach with spacers. Take the tip of the spacers and insert them into
the slots. After doing this to all the slots, you can slide the board into position aligned with slots.
After the board has been positioned, check to make sure everything is OK before putting the
chassis back on.

To install this motherboard:

1. Locate all the screw holes on
the motherboard and the
chassis base.

2. Place all the studs or spacers
needed on the chassis base
and have them tightened.

3. Face the motherboard’s I/O
ports toward the chassis’s rear
panel.

4. Line up all the motherboard’s
screw holes with those studs o
spacers on the chassis.

5. Install the motherboard with
screws and have them
tightened.

※ To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if

they are already fastened on the chassis base and are without mounting-holes
on the motherboard to align with.

Face the chassis’s rear panel.

2.3 Checking Jumper Settings

For a 2-pin jumper, plug the jumper cap on both pins will make it CLOSE (SHORT). Remove the
jumper cap, or plug it on either pin (reserved for future use) will leave it at OPEN position.

SHORT OPEN OPEN

For 3-pin jumper, pin 1~2 or pin 2~3 can be shorted by plugging the jumper cap in.

Pin 1~2 SHORT Pin 2~3 SHORT
