Hardware Setup
If your motherboard has already been installed in your computer you may still need
to refer to this chapter if you plan to upgrade your system's hardware.
This mother
board is electrostatic sensitive. Do not touch without
wearing proper safety gadget and make sure to disconnect the
power cable from the power source before performing any work on
your motherboard. Not doing so may result in electrical shock!
2-1 Installing a CPU Processor in Socket A
The Socket A, designed for AMD Duron/Athlon/Athlon XP processors, has been
incorporated as a standard motherboard specification. To insert your CPU into Socket A
please do the following:
1.
Locate a cut edge on the top surface of the CPU, which is close to one of the
CPU corners. The same corner will also be cut off, leaving a noticeable notch
in the CPU's corner. These markings indicate Pin 1 on the CPU.
2.
Pull up the lever of Socket A so that it is perpendicular with the surface of the
motherboard. Gently insert the CPU with Pin 1 at the same corner of Socket
A, which is located close to the end of the lever. Allow the weight of the CPU
to push itself into place. Do not apply extra pressure as doing so may result
in damaging your CPU. Snap the lever back into place.
Installing an AMD®
approved heat sink with cooling fan is
necessary for proper heat dissipation from your CPU. Failing to
install these items may result in overheating a
nd possible burnout of
your CPU.
Notes: In order to boot up with a newly installed CPU, AC Power must be switched
off before installation.
2-2 Setting Your CPU’s Performance
Frequency Configuration:
This motherboard uses a new user-friendly technology that enables the user to setup a
main board’s CPU parameters through an easy to use BIOS setup procedure. It is no
Chapter 2
6
longer necessary to make many jumper settings as on conventional motherboard.
After installing all your hardware into your PC system, you can manually configure
your CPU clock according to your processor’s specifications. By turning on your
system’s power. Enable the CMOS Setup Utility by pressing the delete key when your
BIOS identification screen appears, then go to the Frequency/ Voltage control option
and select your CPU clock speed (please refer to Chapter3 for more details).
You do not need to make voltage settings because this board will
automatically set your CPU voltage.
2-3 Main Memory Configuration
The DDR SDRAM memory system consists four banks, each bank supports up to
1GB of memory.

2-5 Connector and Jumper Settings
Connectors are used to link the system board with other parts of the system, including
the power supply, the keyboard, and the various controllers on the front panel of the
system case.
The power supply connector is the last connection to be made while installing a
motherboard. Before connecting the power supply, please make sure it is not
connected to the power source.
Note
: All cables are security-proof.
PW1 (ATX Power Supply Connector)
The power cord leading from the system's power supply to the external power source
must be the very last part connected when assembling a system. The ATX power
supply provides a single 20-pin connector interface, which incorporates standard +/-5V,
+/-12V, optional 3.3V and soft-power signals. The soft-power signal, a 5V trickle
supply is continuously supplied when AC power is available. When the system is in the
Soft-Off mode, this trickle supply maintains the system in its minimum power state.
Power-On By Modem
While in Soft-Off state, if an external modem ring-up signal occurs, the system wakes
up and can be remotely accessed. You may enable this function in BIOS's Power
Management Setup menu. (See section
3.5
)
Blinking LED in Suspend Mode
While in Suspend mode, the LED light on the front panel of your computer will flash.
Suspend mode is entered by pressing the Override Power Button
, pushing the Green
button on your ATX case, or enabling the Power Management and Suspend Mode
options in BIOS's Power Management menu. (See section 3.5)
Poly-fuse Over Current Protection
The poly-fuse protects the system from dangerous voltages that the system might be
exposed to via the keyboard or USB connector. In case of such exposure, the poly-fuse
will immediately be disconnected from the circuit, just like a normal fuse. After being
disconnected for a certain period of time, the poly-fuse will return to its normal state.
Then the keyboard or USB connector can function properly again. Unlike conventional
fuses, the poly-fuse does not have to be replaced, relieving the user wasted time and
inconvenience.

CN1A (Front Panel Connector) A through F
A. PWR-SW (Over-ride Power Button Connector)
The power button on the ATX chassis can be used as a normal power switch as well
as a device to activate Advanced Power Management Suspend mode. This mode is
used for saving electricity when the computer is not in use for long periods of time.
The Soft-OFF by PWR-BTN function in BIOS's Power Management Setup menu
must be set to [
Delay 4 Sec
.] to activate this function.
When the Soft-OFF by PWR-BTN function is enabled, pushing the power button
rapidly will switch the system to Suspend mode. Any occurrence of external
activities such as pressing a key on the keyboard or moving the mouse will bring the
system back to Full-On. Pushing the button while in Full-On mode for more than [
4
seconds] will switch the system completely off. See Over-ride Power Button
Operation diagram.
B. P-LED (Power LED Connector)
The power indicator LED shows the system's power status. It is important to pay
attention to the correct cables and pin orientation (i.e., not to reverse the order of these
two connectors.)
C. G-BTN/G-LED (Green Button Switch/LED Connector)
Some ATX cases provide a Green button switch, which is used to put the system in
Suspend mode. In Suspend mode, the power supply to the system is reduced to a
trickle, the CPU clock is stopped, and the CPU core is in its minimum power state.
The system is woken up whenever the keyboard or mouse is touched. The system
resumes in different ways as defined by Power Management Setup screen in BIOS.
D. RESET (System Reset Switch Connector)
This connector should be connected to the reset switch on the front panel of the
system case. The reset switch allows you to restart the system without turning the
power off.
E. SPEAKER (Speaker Connector)
This 4-pin connector connects to the case-mounted speaker
F. HD-LED (IDE Activity LED Connector)
The IDE activity LED lights up whenever the system reads/writes to the IDE
devices.

FD1 (Floppy Disk Connector)
This connector is used to connect 34 pins of Floppy.

This connector is used for connecting 40 pins of ATAPI devices.
IDE 1 only connects two IDE devices. (
Primary
Master/Slave)
IDE 2 only connects two IDE devices. (Secondary Master/Slave)

3. Connect the system's power and then start the system.
4. Enter BIOS's CMOS Setup Utility and choose Load Setup Defaults. Type [Y] and
press [
enter
].
5. Set the system configuration in the Standard CMOS Setup menu.

This connector give you the option of a front panel audio jack cable ext. to be plug
into a special custom designed system case.
Simply remove the two jumper caps at pin [5-6] and [9-10] then plug it into the
(optional) cable ext. connector. Pin [
5-6
] and [
9-10
] are shorted (default) to enable the
back panel audio function.
FAN1/FAN2/FAN3 (CPU/System/Case Cooling Fan Connectors)
The board's management extension hardware is able to detect the CPU and system fan
speed in rpm (revolutions per minute). The wiring and plug may vary depending on
the manufacturer. On standard fans, the red is positive (+12V), the black is ground,
and the yellow wire is the rotation signal.
