Chapter 2 Hardware Setup
2.1 Choosing a Computer Chassis
The motherboard and its component layouts illustrated in this chapter are only for
reference.
• 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) 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 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 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.
To prevent shorting the motherboard, REMOVE the any unused metal studs or spacers from
the chassis.

2.3 Installing CPU and CPU Cooler
Before installing the CPU:
1. Please make sure that the motherboard supports the CPU.
2. Please take note of the indented corners of the CPU. If you install the CPU in the wrong
direction, the CPU will not insert properly. If this occurs, please change the insert direction
of the CPU.
3. Please add an even layer of thermal paste between the CPU and CPU cooler.
4. Please make sure the CPU cooler is installed on the CPU prior to system use, otherwise
overheating and permanent damage of the CPU may occur.
5. Please set the CPU host frequency in accordance with the processor specifications. It is not
recommended that the system bus frequency be set beyond hardware specifications since
it does not meet the required standards for the peripherals. If you wish to set the frequency beyond the proper specifications, please do so according to your hardware
specifications including the CPU, graphics card, memory, hard drive, etc.
2.3.1 Installation of the CPU
1. Unlock the socket by pressing the
lever sideways, then lift it up to a 90 .
2. Position the CPU above the socket such
that the CPU corner with the gold
triangle matches the socket corner with
a small triangle.
3. Carefully insert the CPU into the socket
until it fits place.

2.3.2 Installation of the CPU Cooler
For proper installation, please kindly refer to the instruction manuals of your CPU Cooler.
2.4 Installation of Memory Modules
This motherboard provides four 240-pin DDRII (Double Data Rate) DIMM slots, and supports
Dual Channel Memory Technology. For dual channel configuration, you always need to install
two identical (the same brand, speed, size and chip-type) memory modules in the DDRII
DIMM slots to activate Dual Channel Memory Technology. Otherwise, it will operate at single
channel mode.
Static electricity can damage the electronic components of the computer or optional
boards. Before starting these procedures, ensure that you are discharged of static
electricity by touching a grounded metal object briefly.
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 fits 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.
Under POWER ON:
• The LED of PWR_LED will light.
• The LED of LED_DIMM1 will light
• The LED of LED_DIMM2 will light
• The LED of LED_DIMM3 will light
• The LED of LED_DIMM4 will light

Chapter 3 Jumpers & Headers Setup
3.1 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.
• For 3-pin jumper, pin 1~2 or pin 2~3 can be
shorted by plugging the jumper cap in.
How to identify the PIN1 jumpers?
Please check the motherboard carefully, the PIN1
is marked by "1" or white thick line.
3.2 CMOS Memory Clearing Header
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 1 and 2 shorted
(Default): Normal
operation.
• Pins 2 and 3 shorted:
Clear CMOS memory.

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 first 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 first 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
configures 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 configure 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.

APPENDIX 1
AMIBIOS Check Point and Code List:
1.Bootblock Initialization Code Checkpoints
The Bootblock initialization code sets up the chipset, memory and other
components before system memory is available. The following table describes the
type of checkpoints that may occur during the bootblock initialization portion of
the BIOS:
Checkpoint
Description
Before D1
Early chipset initialization is done. Early super I/O
initialization is done including RTC and keyboard controller.
NMI is disabled.
D1
D0
D2
D3
D4
D5
D6
D7
D8
D9
DA
Perform keyboard controller BAT test. Check if waking up
from power management suspend state. Save power-on
CPUID value in scratch CMOS.
Go to flat mode with 4GB limit and GA20 enabled. Verify the
bootblock checksum.
Disable CACHE before memory detection. Execute full
memory sizing module. Verify that flat mode is enabled.
If memory sizing module not executed, start memory refresh and do memory sizing in Bootblock
code. Do additional chipset initialization. Re-enable CACHE. Verify that flat mode is enabled.
Test base 512KB memory. Adjust policies and cache first 8MB. Set stack.
Bootblock code is copied from ROM to lower system memory and control is given to it. BIOS now
executes out of RAM.
Both key sequence and OEM specific method is checked to determine if BIOS recovery is forced.
Main BIOS checksum is tested. If BIOS recovery is necessary, control flows to checkpoint E0. See
Bootblock Recovery Code Checkpoints section of document for more information.
Restore CPUID value back into register. The Bootblock-Runtime interface module is moved to
system memory and control is given to it. Determine whether to execute serial flash.
The Runtime module is uncompressed into memory. CPUID information is stored in memory.
Store the Uncompressed pointer for future use in PMM. Copying Main BIOS into memory. Leaves
all RAM below 1MB Read-Write including E000 and F000 shadow areas but closing SMRAM.
Restore CPUID value back into register. Give control to BIOS POST (ExecutePOSTKernel). See
POST Code Checkpoints section of document for more information.
2.Bootblock Recovery Code Checkpoints
The Bootblock recovery code gets control when the BIOS determines that a
BIOS recovery needs to occur because the user has forced the update or the
BIOS checksum is corrupt. The following table describes the type of checkpoints
that may occur during the Bootblock recovery portion of the BIOS:
Checkpoint
Description
E0
Initialize the floppy controller in the super I/O. Some interrupt vectors are initialized. DMA
controller is initialized. 8259 interrupt controller is initialized. L1 cache is enabled.
E9
Set up floppy controller and data. Attempt to read from floppy.
EA
Enable ATAPI hardware. Attempt to read from ARMD and ATAPI CDROM.
EB
Disable ATAPI hardware. Jump back to checkpoint E9.

Checkpoint
Description
EF
Read error occurred on media. Jump back to checkpoint EB.
E9 or EA
Determine information about root directory of recovery media.
F0
Search for pre-defined recovery file name in root directory.
F1
Recovery file not found.
F2
Start reading FAT table and analyze FAT to find the clusters occupied by the recovery file.
F3
Start reading the recovery file cluster by cluster.
F5
Disable L1 catche
FA
Check the validity of the recovery file configuration to the current configuration of the flash part.
FB
Make flash write enabled through chipset and OEM specific method. Detect proper flash part.
Verify that the found flash part size equals the recovery file size.
F4
The recovery file size does not equal the found flash part size.
FC
Erase the flash part.
FD
Program the flash part.
FF
The flash has been updated successfully. Make flash write disabled. Disable ATAPI hardware.
Restore CPUID value back into register. Give control to F000 ROM at F000:FFF0h.
3.POST Code Checkpoints
The POST code checkpoints are the largest set of checkpoints during the BIOS preboot process. The following table describes the type of checkpoints that may occur
during the POST portion of the BIOS:
Checkpoint
03
04
05
06
08
Description
Disable NMI, Parity, video for EGA, and DMA controllers. Initialize BIOS, POST, Runtime data area.
Also initialize BIOS modules on POST entry and GPNV area. Initialized CMOS as mentioned in the
Kernel Variable "wCMOSFlags."
Check CMOS diagnostic byte to determine if battery power is OK and CMOS checksum is OK.
Verify CMOS checksum manually by reading storage area. If the CMOS checksum is bad, update
CMOS with power-on default values and clear passwords. Initialize status register A. Initializes
data variables that are based on CMOS setup questions. Initializes both the 8259 compatible PICs
in the system
Initializes the interrupt controlling hardware (generally PIC) and interrupt vector table.
Do R/W test to CH-2 count reg. Initialize CH-0 as system timer. Install the POSTINT1Ch handler.
Enable IRQ-0 in PIC for system timer interrupt. Traps INT1Ch vector to "POSTINT1ChHandlerBlock
."
Initializes the CPU. The BAT test is being done on KBC. Program the keyboard controller command
byte is being done after Auto detection of KB/MS using AMI KB-5.
C0
