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 s tatic 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 board is an MicroATX sized motherboard supporting the latest gen­eration of AMD® processors at industry leading speeds. By utilizing DDR (
Double Data Rate ) transfer rate the 100/133/166 MHz system bus effectively
reaches Front Side Bus speeds of 200/266/333 MHz. The board provides users
with an ATA133 data transaction for hard drives and allows up to 2 GB memory
totally by 2 DDR 200/266/333 SDRAM DIMM sockets.

The mainboard is based around the high performance KM400 core chip with
VIA VT8235CE as a South Bridge. The video functions supported by KM400
provides you with a photo-realistic 3D experience suitable for the most robust
3D games and software environments. AC97 Cod ec that embedded in
VT8235CE, ensures high quality video and audio effect. The mainboard fea­tures onboard audio with 5.1-channel, 1 SPDIF_OUT for digital audio output.

The mainboard also comes equipped with the new NOVUS® range of innova­tive features that assist in the installation and maintenance. The features in­clude Easy Key, which provides instant keyboard access to the BIOS for ad-
justments to default settings; and the BIOS Guardian is an Anti Virus utility
that prevents viruses from damaging your system BIOS and rendering your
system inoperative.

Expansion is provided by 1 AGP 8X and 3 PCI slots. In addition, the board is
equipped standard I/O connections include 1 serial port , 1 parallel port, 1 CRT
port, 1 PS/2 mouse and 1 PS/2 keyboard connector, 6 USB 2.0 ports (2 ports by
onboard pinheaders), 2 IR ports, and 1 media connector (Line-In, Line-Out,
Mic-In, 1 front audio).

Installation Procedures

The main board has several user-adjustable jumpers on the board that allow you to
configure your system to suit your requirements. This chapter co ntains information
on the various jumper settings on your mainboard.

To set up your compu ter, you must complete the following steps:

n Step 1 - Set system jumpers
n Step 2 - Install memory modules
n Step 3 - Install the Central Processing Unit (CPU)
n Step 4 - Install expansion cards
n Step 5 - Connect ribbon cables, cabinet wires, and power supply
n Step 6 - Set up BIOS software
n Step 7 - Install supporting software tools

WARNING: Excessive torque may damage the mainboard. When
using an electric screwdriver on the mainboard, make sure that
the torque is set to the allowable range of 5.0 ~ 8.0kg/cm.

Mainboard components contain very delicate Integrated Circuit
(IC) chips. To prevent static electricity from harming any of the
sensitive components, you should follow the following precau­tions whenever working on the computer:

1. Unplug the computer when working on the inside.

2. Hold components by the edges and try not to touch the IC

||||chips, leads, or circuitry.

3. Wear an anti-static wrist s trap which fits around the wrist.

4. Place components on a grounded anti-static pad or on the bag
that came with the component whenever the c omponents are
separated from the system.

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.

3). Install the CPU

The mainboard has built-in Switch­ing Voltage Regulator to support
CPU Vcore autodetection. That is,
it has the ability to detect and rec­ognize the CPU voltage, clock and
ratio.

When you install your CPU on this mainboard, please use a power supply that
designed and manufactured only for CPU use. Your CPU fansink combined
with its retention module must be completely closed and firmly attached on the
top of the processor.

2 - 7

AM39L Mainboard Manual

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. 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. Place the cooling fan with heatsink on top of the installed CPU.

NOTE: Users The CPU installing procedures should be:

1. Insert the CPU (with its fansink and retention module) on the

socket.

2. Connect the 4-pin plug of the power supply.

3. Connect the 20-pin plug of the power supply
To remove the process or, please do it in reverse order.

4). Install Expansion Cards

This section describes h ow to connect an expansion card to one of your
system expansion slots. Expansion cards are printed circuit boards that, when
connected to the main board, increase the capabilities of your system. For
example, expansion cards can p rovide video and sound capabilities. The
mainboard features one AGP slot and three PCI bus expansion slots.

2 - 8

Installation Procedures

CAUTION: Make sure to unplug the power supply when adding or
removing expansion cards or other system components. Failure to
do so may cause sev ere 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 computer 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.

4. Push the card firmly in to 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.
