Chapter 2 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 motherboard 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 for Socket A

The Socket A, designed for AMD® Athlon XP/Athlon/Duron 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 close to one if it’s corners. The
same corner will also be cut off, leaving a noticeable notch in the CPU’s corner.
These markings indicate Pin 1 of the CPU.

2. Pull up the lever of Socket 462 so that it is perpendicular with the surface of the
motherboard. Gently insert the CPU with Pin 1 at the same corner of Socket 462
that contains 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.

3. 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 and possible burnout of your CPU.

Notes: In order to boot up with a newly installed CPU, AC Power must be switched off

before installation.

2-4 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.
The ATX 12V power supply has a new +12V (4-pin) and +5V/3.3V (6-pin) auxiliary
power connector in order to enable the delivery of more +12 VDC and +5/3.3V VDC
current to the motherboard.

Chapter 2

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 from such
inconveniences.

CN1A (Front Panel Connector)

1. 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 idle for long a period of
time. The Soft-OFF by PWR-BTTN 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-BTTN 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

9

Chapter 2

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.

2. P-LED (Power LED Connector)

The power indicator LED shows the system's power status. It is important to pay
attention to the correct cable and pin orientation (i.e. Remember not to reverse the
order of these two connectors.)

3. 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 activated whenever the keyboard or mouse is touched. The
system can be resumed in different ways as defined by Power Management Setup
screen in BIOS.

4. 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.

5. SPEAKER (Speaker Connector)

This 4-pin connector connects to the case-mounted speaker.

6. HD-LED (IDE Activity LED Connector)

The IDE activity LED lights up whenever the system reads/writes to the IDE
devices.

3-1 Standard CMOS Setup

The Standard CMOS Setup allows users to configure system components such as hard
disk drive, floppy disk drive and video display as well as date, time and boot-up error
signaling. This configuration menu should be changed when installing a motherboard for
the first time, changing hardware in your system such as the HDD, FDD, video display,
or when the CMOS data was corrupted. Choose the Standard CMOS Setup option from
the CMOS Setup Utility menu (Figure 3-1) to display the following screen.

Date/Time

Set the date and time of the system. Do not skip this function as all of your timed events
such as power management, saving files, etc are based on this timer.

IDE (Primary/Secondary; Master/Slave)

This category identifies up to four IDE hard disk drives that have been installed in the
computer. This section does not show information on other IDE devices such as
CD-ROM drives or other hard drive type such as SCSI drives.

Drive A/B

Select different Floppy device Model. Available options are [None], [360K, 5-1/4 in],
[1.2M, 5-1/4 in], [720k, 3-1/2 in], [1.44M, 3-1/2 in], and [2.88M, 3-1/2 in].

Video

Select the type of video adapter present in your system. You can ignore this setting if you
are using a VGA monitor; VGA BIOS will automatically configure this setting.

Halt On

When the system is powered on, BIOS performs a series of diagnostic tests called POST
(Power On Self Test). This function stops the computer if BIOS detects a hardware error.
You can tell BIOS to halt on all errors, no errors, or not to halt on specific errors.

19

Chapter 3

3-2 Advanced BIOS Features

By choosing the [Advanced BIOS Features] option from the CMOS Setup Utility menu (Figure 3-1), the screen below is displayed. This sample screen contains the manufacturer's default values for the motherboard.

Virus Warning

When you set as enabled, you receive a warning message if a program (specifically, a
virus) attempts to write to the boot sector or the partition table of the hard disk drive.

Many disk diagnostic programs that access the boot sector table can trigger the
virus-warning message. If you plan to run such a program, we recommend that
you first disable the virus warning.

CPU Internal Cache / External Cache

Cache memory is much faster than conventional DRAM system memory. These fields
allow you to enable or disable the CPUs Level 1 built-in cache and Level 2 external
cache. Both settings are left enabled to significantly increase the performance of your
computer.

CPU L2 Cache ECC Checking

Enable this function for the CPU L2 Cache Error Checking and Correcting (ECC)
operation.

Quick Power On Self Test

Enable this function to reduce the amount of time required to run the POST (Power On
Self Test). BIOS will save time by skipping some items during POST. It is recommended
that you disable this setting. Discovering a problem during boot up is better than loosing
