Chapter 2 Hardware Setup
2.1 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
sufcient 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 conguration of this Motherboard. You can nd
an I/O shield specically 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) 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.
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 or spacers on the chassis.
5. Install the Motherboard with screws and have them tightened.
The Motherboard and its component layouts illustrated in this chapter were
based mainly on model “A75 Series”, unless specically stated.
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.
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

2.4 Installation of Memory Modules
This Motherboard provides four 240-pin DDRIII (Double Data Rate) DIMM slots, and
supports
Dual Channel Memory Technology. For dual channel conguration, you always need to install
two identical (the same brand, speed, size and chip-type) memory modules in the DDRIII
DIMM slots to activate Dual Channel Memory Technology. Otherwise, it will operate at single
channel mode.
One DIMM:Install one memory module into DIMM 1 or DIMM 2 rst as a single-channel
operation.
Two DIMMs (dual-channel operation):
Install two memory modules into DIMM 1 and DIMM 3 or DIMM 2 and DIMM 4 rst as a dual-
channel operation.
Four DIMMs (dual-channel operation):
Install four memory modules into DIMM 1 and DIMM 2 and DIMM 3 and DIMM 4 rst as a
dual-channel operation.
To install system memory:
1. Power off the computer and unplug the
AC power cord before installing or
removing memory modules.
2. Locate the DIMM slot on the board.
3. Hold two edges of the DIMM module
carefully, keep away from touching its
connectors.
4. Align the notch key on the module with
the rib on the slot.
5. Firmly press the module into the slots until the ejector tabs at both sides of the slot
automatically snap into the mounting notch. Do not force the DIMM module in with extra
force as the DIMM module only ts in one direction.
6. To remove the DIMM modules, push the two ejector tabs on the slot outward
simultaneously, and then pull out the DIMM module.
Static electricity can damage the electronic components of the computer or optional
boards. Before starting these procedures, ensure that you are discharged of static

Chapter 4 BIOS Setup Utility
BIOS stands for Basic Input and Output System. It was once called ROM BIOS when it was
stored in a Read-Only Memory (ROM) chip. Now manufacturers would like to store BIOS in
EEPROM which means Electrically Erasable Programmable Memory. BIOS used in this series
of Motherboard is stored in EEPROM, and is the rst program to run when you turn on your
computer.
BIOS performs the following functions:
1. Initializing and testing hardware in your computer (a process called "POST", for Power On
Self Test).
2. Loading and running your operating system.
3. Helping your operating system and application programs manage your PC hardware by
means of a set of routines called BIOS Run-Time Service.
4.1 About BIOS Setup
BIOS Setup is an interactive BIOS program that you need to run when:
1. Changing the hardware of your system. (For example: installing a new Hard Disk etc.)
2. Modifying the behavior of your computer. (For example: changing the system time or date,
or turning special features on or off etc.)
3. Enhancing your computer's behavior. (For example: speeding up performance by turning
on shadowing or cache)
4.2 To Run BIOS Setup
First access BIOS setup menu by pressing <F1> key after “POST” is complete (before OS is
loaded). After the rst BIOS be setupped(or loaded default values) and save, the <DEL> key
will be pressed if you will enter BIOS setup menu.
4.3 About CMOS
CMOS is the memory maintained by a battery. CMOS is used to store the BIOS settings you
have selected in BIOS Setup. CMOS also maintains the internal clock. Every time you turn
on your computer, the BIOS Looks into CMOS for the settings you have selected and
congures your computer accordingly. If the battery runs out of power, the CMOS data will
be lost and POST will issue a “CMOS invalid” or “CMOS checksum invalid” message. If this
happens, you have to replace the battery and check and congure the BIOS Setup for the
new start.
4.4 The POST (Power On Self Test)
POST is an acronym for Power On Self Test. This program will test all things the BIOS does
before the operating system is started. Each of POST routines is assigned a POST code, a
unique number which is sent to I/O port 080h before the routine is executed.
