Handling Precautions

Warning:

1. Static electricity may cause damage to the integrated circuits on

the motherboard. Before handling any motherboard outside of its
protective packaging, ensure that there is no static electric charge
in your body.

2. There is a danger of explosion if the battery is incorrectly
replaced. Replace only with the same or an equivalent type
recommended by the manufacturer.

3. Discard used batteries according to the manufacturer’s
instructions.

4. Never run the processor without the heatsink properly and firmly

attached. PERMANENT DAMAGE WILL RESULT!

Observe the following basic precautions when handling the motherboard

or other computer components:

n Wear a static wrist strap which fits around your wrist and is

connected to a natural earth ground.

n Touch a grounded or anti-static surface or a metal fixture such as a

water pipe.

n Avoid contacting the components on add-on cards, motherboards,

and modules with the golden fingers connectors plugged into the

expansion slot. It is best to handle system components by their

mounting brackets.

The above methods prevent static build-up and cause it to be discharged

properly.

Overview

The new 1stMainboard® AT31Ô is an Micro ATX sized motherboard sup-

porting the latest generation of AMD® processors at industry leading speeds.

By utilizing DDR ( Double Data Rate ) transfer rate the 100/133 MHz system bus

effectively reaches Front Side Bus speeds of 200/266 MHz. The board pro-

vides users with an ATA100 data transaction for hard drives and allows up to

2 GB memory totally by 2 PC1600/PC2100 (DDR200/266) DIMM sockets.

The AT31 is based around the high performance ATI IGP320Ô core chip as a
North Bridge and VIA VT82686BÔ as a South Bridge. The virtual AGP4x
functions supported by ATI IGP320Ô that ideal for Windows 2000Ô pro-

vides you with a photo-realistic 3D experience suitable for the most 3D games

and software environments. AC97 Codec that embedded in VIA 686B, ensures

high quality sound effect.

The mainboard also comes equipped with the new NOVUS® range of innova-

tive features that assist in the installation and maintenance. The features in-

clude Easy Key, which provides instant keyboard access to the BIOS for

adjustments to Clock and Default settings and LogoGenie, which allows you

to create your own customized logo to be displayed during system boot up.

The BIOS Guardian is an Anti Virus utility that prevents viruses from damag-

ing your system BIOS and rendering your system inoperative.

Expansion is provided by 1 AGP 4X and 3 PCI slots. In addition, the

1stMainboard is equipped standard I/O connections include 2 serial ports (1

by pinheader), 1 parallel port, 1 VGA port, 1 PS/2 mouse and keyboard connec-

tor, 4 USB ports (2 by pinheader), 1 IR port by pinheader, and 1 media connec-

tor (Line-In, Line-Out, Mic-In, 1 front audio, 1 game port).

2). Front Panel Block Cable Connection

3). CPU Fan Installation

CAUTION:

1. The heatsink and fan you installed must be approved by AMD.

2. The mainboard must be placed on a solid place to avoid shaking

|||||while install the heatsink and fan on the board.

3. The heatsink must be contact with the CPU top tightly.

4. Never run the processor without the heatsink properly and firmly

attached. PERMANENT DAMAGE WILL RESULT!

Without sufficient air circulation, the CPU may overheat resulting in damage

to both the CPU and the mainboard.

Damage may occur to the mainboard and/or the CPU fan if these pins are

used incorrectly. These are not jumpers, do not place jumper caps over these

pins.

2 - 4

Installation Procedures

1). Set System Jumpers/Switches

Jumpers are used to select the operation modes for your system. Some jump-

ers on the board have three metal pins with each pin representing a different

function. A 1 is written besides pin 1 on jumpers with three pins. To set a

jumper, a black cap containing metal contacts is placed over the jumper pin/s

according to the required configuration. A jumper is said to be shorted when

the black cap has been placed on one or two of its pins. The types of jumpers

used in this manual are shown below:

NOTE: Users are not encouraged to change the jumper settings
not listed in this manual. Changing the jumper settings improperly
may adversely affect system performance.

Clear CMOS: J3

The CMOS RAM is powered by the onboard button cell battery. To clear the

RTC data: (1) Turn off your computer (2) Place the jumper cap onto the pinpair

2-3 at least 6 seconds to clear CMOS (3) Place the jumper cap onto the pinpair

1-2 to Normal (4) Turn on your computer until CMOS checksum error appears

(5) Hold down the Delete key when boots (6) Enter the BIOS Setup to re-enter

user preferences.

Installation Procedures

2). Install Memory Modules

1. Locate the DIMM slots on the mainboard.

2. Install the DIMM straight down into the DIMM slot using both hands.

3. The clip on both ends of the DIMM slot will close up to hold the DIMM

in place when the DIMM reaches the slot bottom.

Press the clips with both hands to remove the DIMM.

A T31 Mainboard Manual

3). Install the CPU

The AMD CPU module resides in the socket on the board. Please follow the

steps introduced below to complete the CPU installation.

CAUTION:

1. The heat sink and fan you installed must be approved by AMD.

2. The mainboard must be placed on a solid place to avoid shaking

|||||while install the heat sink and fan on the board.

3. The heat sink must be contact with the CPU top tightly.

4. Never run the processor without the heat sink properly and firmly

attached. PERMANENT DAMAGE WILL RESULT!

To install the CPU, do the following:

1. Lift the lever on the side of the CPU socket.

2. Handle the chip by its edges and try not to touch any of the pins.

3. Place the CPU in the socket. The chip has two notches to correctly locate

the chip. Align two notches of the processor with the two triangular

marks on the socket. Do not force the chip. The CPU should slide easily

into the socket.

4. Swing the lever to the down position to lock the CPU in place.

5. Install the cooling fan with heat sink on top of the installed CPU.

6. Place the mainboard (with the CPU, its cooling fan, and heat sink) into the

system chassis and affix it with screws.

Installation Procedures

4). Install Expansion Cards

This section describes how to connect an expansion card to one of your

system expansion slots. Expansion cards are printed circuit boards that, when

connected to the mainboard, increase the capabilities of your system. For

example, expansion cards can provide video and sound capabilities. The

mainboard features one AGP and three PCI bus expansion slots.

CAUTION: Make sure to unplug the power supply when adding or
removing expansion cards or other system components. Failure to
do so may cause severe damage to both the mainboard and
expansioncards.
Always observe static electricity precautions.
Please read Handling Precautions at the start of this manual.

To install an expansion card, follow the steps below:

1. Remove the chassis cover and select an empty expansion slot.

2. Remove the corresponding slot cover from the computer chassis.

Unscrew the mounting screw that secures the slot cover and pull

the slot cover out from the computer chassis. Keep the slot cover

mounting screw nearby.

3. Holding the edge of the peripheral card, carefully align the edge

connector with the expansion slot.

2 - 9

A T31 Mainboard Manual

4. Push the card firmly into the slot. Push down on one end of the

expansion card, then the other. Use this rocking motion until the add-

on card is firmly seated inside the expansion slot.

5. Secure the board with the mounting screw removed in Step 2. Make

sure that the card has been placed evenly and completely into the

expansion slot.

6. Replace the computer system cover.

7. Setup the BIOS if necessary.

8. Install the necessary software drivers for the expansion card.

reflash BIOS:

1. Press Del key while booting. Go to CMOS Setup Utility menu.

2. Go to Advanced BIOS Features submenu.

3. Set the feature BIOS Guardian at Disabled.

4. Save the setting and exit. The system restarts.

5. POST screen holds. A message about BIOS Guardian shows.

6. Press Space bar.

7. Reflash BIOS. Restart the system after complete it.

8. POST screen holds. A message about BIOS Guardian shows.

9. Press G key. The feature BIOS Guardian will be enabled again.

2. If you create a Logo file (.bmp) by LogoGenie, the file size must

||||be 640 x 464 x 256 colors.

To enable this utility, please proceed as follows:

1. Insert CD Pro. Select LogoGenie from the Menu

and follow the installation instructions.

2. After LogoGenie has been installed, go to Windows Start Box.
