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 to enable the delivery of more +12 VDC and +5/3.3V VDC current to

8

Chapter 2

the motherboard.

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)

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 is a power- saving

mode used for saving electricity when the computer is not in use for a long 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

9

Chapter 2

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.

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. Be Careful 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 resumes in various

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.

FD1 (Floppy Connector)

The motherboard provides a standard floppy disk drive connector that supports 360K,

720K, 1.2M, 1.44M and 2.88M floppy disk types. Use this connector to connect to a

floppy disk drive of 34 pins.

Chapter 3

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.

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.

Figure 3-3

Virus Warning

When you set it 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 as Enabled to significantly increase the performance of your

computer.

18

Chapter 3

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

data during your work.

First/Second/Third/Boot Other Device

This option sets the sequence of drives BIOS attempts to boot from after POST completes.

BIOS will search these drives for an operating system.

Swap Floppy Drive

Enabling this function will swap the floppy drive assignment so that drive A will function

as drive B, and drive B will function as drive A. Note that the boot sequence assignment

mentioned directly above does not include booting from floppy drive B. This function is

useful if floppy drives B and A are of a different format and you want to boot from floppy

drive B.

corrupted and therefore unusable, these defaults will be loaded automatically when you

turn on the computer.

3-9 Load Optimized Defaults

Load Optimized Defaults loads the default system values directly from the CMOS

Setup Utility menu (Figure3-1). If the stored record created by the setup program

becomes corrupted and therefore unusable, these defaults will be loaded automatically

when you turn on the computer.

3-10 Supervisor Password & User Password Setting

There are four different variables that control password settings. The first two are

located under the Security Option function in BIOS Features Setup Menu (Figure 3-1).

When the Security Option function is set to Setup, a password is required to enter BIOS

and change BIOS settings. When the Security Option function is set to System, a

password is required to enter both BIOS and the computer's operating system (for

example Windows 98) found on the boot drive.

The third and fourth variables are user password and supervisor password selected in

BIOS (Figure 3-1). The main purpose of separating user and supervisor is to allow only

the supervisor to have control over the settings in BIOS. The user, on the other hand, is

only allowed to access the computer's operating system and change the user password in

BIOS.

When there is no supervisor password set, the user password controls access to

all BIOS settings.
