Chapter 2 Hardware Setup
2.1 Choosing a Computer Chassis
• Choose a chassis big enough to install this mainboard.
• As some features for this mainboard are implemented by cabling connectors on the
mainboard 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 mainboard. You can nd
an I/O shield specically designed for this mainboard in its package.
2.2 Installing Mainboard
Most computer chassis have a base with many mounting holes to allow the mainboard to
be securely attached, and at the same time, prevent the system from short circuits. There
are two ways to attach the mainboard 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 mainboard:
1. Locate all the screw holes on the mainboard and the chassis base.
2. Place all the studs or spacers needed on the chassis base and have them tightened.
3. Face the mainboard’s I/O ports toward the chassis’s rear panel.
4. Line up all the mainboard’s screw holes with those studs or spacers on the chassis.
5. Install the mainboard with screws and have them tightened.
The mainboard and its component layouts illustrated in this chapter were
based mainly on model “JW-A780LM-D2 V3.0”, 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
mainboard 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 mainboard to
align with.

AMD Series User's Manual
2.3 Installation of the CPU and CPU Cooler
Before installing the CPU, please comply with the following conditions:
1. Please make sure that the mainboard supports the CPU.
2. Please take note of the one indented corner 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 heat sink 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 specications. It is not
recommended that the system bus frequency be set beyond hardware specications since
it does not meet the required standards for the peripherals. If you wish to set the frequen-
cy beyond the proper specications, please do so according to your hardware
specications 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
o
.
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 ts place.
4. When the CPU is in place, push down
the socket lever to secure the CPU.

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 mainboard provides two 1.8v DDR2 DIMM slots, which supports dual channel memory
technology. To activate the dual channel conguration, you need to install two identical
(same brand, speed, size and chip-type) memory modules into these DIMM slots. Otherwise
the memory will only operate at single channel mode.
For dual channel DDR2 installation:
Populate two DDR2 DIMM modules of the same type and size into slots [DIMM1] + [DIMM2].
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.

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 mainboard 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 modication
on the CPU or memory modules.
This header uses a jumper cap to clear the CMOS
memory and have it recongured 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.

3.9 S/PDIF Output Connection Header (Optional)
S/PDIF (Sony/Philips Digital Interface) is a standard audio transfer le format. It is
usually found on digital audio equipment such as a DAT (Digital Audio Tape) machine or
audio processing device. It allows the transfer of audio from one le to another without
the conversion to and from an analog format, which could degrade the signal quality.

3.10 ATX Power Input Connectors
ATXPWR (ATX Power) connector
We recommend to use our motherboard with a power supply that complies with the ATX12V
Power Supply Design Guide Version 1.1. Every ATX12V power supply unit has a standard
24-pin ATX main power connector that must be plugged into this connector. If you would like
to use an old power supply with only a 20-pin ATX main power connector, then please plug
the 20-pin ATX main power connector along with pin 1 and pin 13.
PWR12V (+12V Power) connector
Your power supply unit may come with a 4-pin +12V power connector. The +12V power
enables the delivery of more +12VDC current to the CPU's Voltage Regulator Module (VRM).

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 mainboard 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 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.

4.5 BIOS Setup — CMOS Setup Utility
4.5.1 CMOS Setup Utility
After powering up the system, the BIOS message appears on the screen,when the rst time
or when CMOS setting wrong, there is following message appears on the screen , but if
the rst BIOS be setuped(or loaded default values) and save, the <DEL> key will be
pressed if you will enter BIOS setup menu.
If this message disappears before you respond, restart the system by pressing <Ctrl> +
<Alt>+ <Del> keys, or by pressing the reset button on computer chassis. Only when these
two methods should be fail that you restart the system by powering it off and then back on.
After pressing <F1> or <Del> key, the main menu appears.
4.5.2 Control Keys
