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 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 an ATX form factor of 305 x 245 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
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
r
spacers on the chassis.
5. Install the motherboard with
screws and have them
tightened.
Face the chassis’s rear panel.
※ 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.
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

Hardware Setup
AW8D 2-3
2.3.1 CMOS Memory Clearing Header and Backup Battery
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.
This header uses a jumper cap to clear the CMOS memory and have it reconfigured to the
default values stored in BIOS.
• Pins 1 and 2 shorted (default): Normal operation.
• Pins 2 and 3 shorted: Clear CMOS memory.
To clear the CMOS memory and load in the default values:
1. Power off the system.
2. Set pin 2 and pin 3 shorted by the jumper cap. Wait for a few seconds. Set the jumper cap
back to its default settings --- pin 1 and pin 2 shorted.
3. Power on the system.
4. For incorrect CPU ratio/clock settings in the BIOS, press <Del> key to enter the BIOS setup
menu right after powering on system.
5. Set the CPU operating speed back to its default or an appropriate value.
6. Save and exit the BIOS setup menu.

CMOS Backup Battery:
An onboard battery saves the CMOS memory to keep the BIOS information stays on even after
disconnected your system with power source. Nevertheless, this backup battery exhausts after
some five years. Once the error message like “CMOS BATTERY HAS FAILED” or “CMOS
checksum error” displays on monitor, this backup battery is no longer functional and has to
be renewed.
To renew the backup battery:
1. Power off the system and disconnect with AC power source.
2. Remove the exhausted battery.
3. Insert a new CR2032 or equivalent battery. Pay attention to its polarity. The “+” side is its
positive polarity.
4. Connect AC power source and power on the system.
5. Enter the BIOS setup menu. Reconfigure the setup parameters if necessary.
CAUTION:
※ Danger of explosion may arise if the battery is incorrectly renewed.
※ Renew only with the same or equivalent type recommended by the battery
manufacturer.
※ Dispose of used batteries according to the battery manufacturer’s instructions.

2.3.2 Wake-up Header
These headers use a jumper cap to enable/disable the wake-up function.
• USB-PWR1:
Pin 1-2 shorted (default): Disable wake-up function support at USB1 port.
Pin 2-3 shorted: Enable wake-up function support at USB1 port.
• USB-PWR2:
Pin 1-2 shorted (default): Disable wake-up function support at USB2 port.
Pin 2-3 shorted: Enable wake-up function support at USB2 port

2.4 Connecting Chassis Components
2.4.1 ATX Power Connectors
These connectors provide the connection from an ATX power supply. As the plugs from the
power supply fit in only one orientation, find the correct one and push firmly down into these
connectors.
ATX 24-Pin Power Connector:
The power supply with 20-pin or 24-pin cables can both be connected to this 24-pin connector.
Connect from pin-1 for either type. However, a 20-pin power supply may cause the system
unstable or even unbootable for the sake of insufficient electricity. A minimum power of 300W
or higher is recommended.
ATX 12V 4-Pin Power Connector:
This connector supplies power to CPU. The system will not start without connecting power to
this one.
Auxiliary 12V Power Connector:
This connector provides an auxiliary power source for devices added on PCI
Express slots.

※ The installation procedures vary with different types of CPU fan-and-heatsink
assembly. The one shown here is served for demo only. For detailed information
on how to install the one you bought, refer to its installation guidelines.
※ A higher fan speed will be helpful for better airflow and heat-dissipation.
Nevertheless, stay alert to touch any heatsink since the high temperature
generated by the working system is still possible.

2.5.2 DDR2 Memory Slots
This motherboard provides four 240-pin DIMM slots for Dual Channel DDR2 800/667/533
memory modules with memory expansion size up to 8GB.
• To reach the optimum performance in dual-channel configurations, install identical DDR2
DIMM pairs for each channel.
• Install DIMMs with the same CAS latency. To reach the optimum compatibility, obtain
memory modules from the same vendor.
• Due to chipset resource allocation, the system may detect less than 4GB of system memory
in the installation of four 1GB DDR2 memory modules.
• Due to chipset limitation, 128MB DIMM modules or double-sided x16 memory chips are not
supported.
There are several methods of different DDR2 configurations depending on how the DIMMs are
populated on each system memory channel:
• [Single Channel]: only one channel is populated.
