1.3 Choosing a Computer Chassis 
 
 
 
 
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.

1.4 Installing Motherboard 
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) with studs, or (2) with spacers. 
Basically, the best way to attach the board is 
with 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. 
※  Always power off the computer and unplug the AC power cord before adding or 
removing any peripheral or component. Failing to so may cause severe damage 
to your motherboard and/or peripherals. Plug in the AC power cord only after 
you have carefully checked everything. 
To install this motherboard: 
1. 
2. 
3. 
4. 
5. 
Locate all the screw holes on the 
motherboard and the chassis base. 
Place all the studs or spacers needed on 
the chassis base and have them tightened.
Face the motherboard’s I/O ports toward 
the chassis’s rear panel. 
Line up all the motherboard’s screw holes 
with those studs or spacers on the chassis.
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.

1.5 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. 
1.5.1 CMOS Memory Clearing Header and Backup Battery 
Pin 1~2 SHORT
 
Pin 2~3 SHORT 
The time to clear the CMOS memory occurs when (a) 
the CMOS data becomes corrupted, (b) you forgot the 
supervisor or user password preset in the BIOS menu, 
(c) you are unable to boot-up the system because the 
CPU ratio/clock was incorrectly set in the BIOS menu, 
or (d) whenever there is modification on the CPU or 
memory modules. 
This header uses a jumper cap to clear the CMOS 
memory and have it reconfigured to the default values 
stored in BIOS. 
 
 
Pins 2 and 3 shorted 
(Default): Normal 
operation. 
Pins 1 and 2 shorted: 
Clear CMOS memory. 
To clear the CMOS memory and load in the default values: 
 
1. 
2. 
3. 
4. 
5. 
6. 
1-4 
Power off the system. 
Set pin 1 and pin 2 shorted by the jumper cap. Wait for a few seconds. Set the jumper 
cap back to its default settings --- pin 2 and pin 3 shorted. 
Power on the system. 
For incorrect CPU ratio/clock settings in the BIOS, press  key to enter the BIOS 
setup menu right after powering on system. 
Set the CPU operating speed back to its default or an appropriate value. 
Save and exit the BIOS setup menu.
