MSI Special Features

Live BIOS™/Live Driver™

The Live BIOS™/Live Driver™ is a tool used to detect and update your BIOS/drivers online so that you don’t need to search for the correct BIOS/driver version throughout the Web site. To use the function, you need to install the “MSI Live Update 2” application. After installation, the “MSI Live Update 2” icon (as shown on the right) will appear on the screen.

Double click the “MSI Live Update 2” icon, and the following screen will appear:

Five buttons are placed on the leftmost pane of the screen. Click the desired button to start the update process.

z Live BIOS – Updates the BIOS online.

z Live Driver – Updates the drivers online.

z Live VGA BIOS – Updates the VGA BIOS online.

z Live VGA Driver – Updates the VGA driver online.

zz zz

z Live Utility – Updates the utilities online.

If the product you purchased does not support any of the functions listed above, a “sorry” message is displayed. For more information on the update instructions, insert the companion CD and refer to the “Live Update Guide” under the “Manual” Tab.

Hardware Setup

Central Processing Unit: CPU

The mainboard supports AMD® Athlon™, Athlon™ XP and Duron™

processors in the 462 pin package. The mainboard uses a CPU socket called Socket-462 for easy CPU installation. When you are installing the CPU, make

sure the CPU has a heat sink and a cooling fan attached on the top to prevent overheating. If you do not find the heat sink and cooling fan, contact

your dealer to purchase and install them before turning on the computer.

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 14

then CPU core speed = Host Clock x Core/Bus ratio

= 100MHz x 14 = 1.4 GHz

CPU Installation Procedures for Socket 462

1. Please turn off the power and unplug the power cord before installing the CPU.

Open Lever

2. Pull the lever sideways away from the socket. Make sure to raise the lever up to a 90degree angle.

3. Look for the gold arrow. The gold arrow should point towards the lever pivot. The CPU can only fit in the correct orientation.

4. If the CPU is correctly installed, the pins should be completely embedded into the socket and can not be seen. Please note that any violation of the correct installation procedures may cause permanent damages to your mainboard.

5. Press the CPU down firmly into the socket and close the lever. As the CPU is likely to move while the lever is being closed, always close the lever with your fingers pressing tightly on top of the CPU to make sure the CPU is properly and completely embedded into the socket.

The following instructions will guide you through the heat sink installation procedures. Please consult your agent for the proper CPU cooler set.

1. Position your CPU cooler set onto the CPU.

2. Use one end of the clip to hook the latch of the CPU sliding plate.

3. Hook the other latch to fix the cooling fan set. You may need a screw drive to press down the other side of the clip.

4. Connect the fan to the power supply connector provided on your mainboard.

Memory

The mainboard provides 3 slots for 184-pin DDR SDRAM DIMM (Double In-Line Memory Module) modules and supports the memory size up to 3GB. You can install PC3200/DDR400, PC2700/DDR333, PC2100/ DDR266 or PC1600/DDR200 modules on the DDR DIMM slots (DDR 1~3).

DDR DIMM Slots

(DDR 1~3)

Introduction to DDR SDRAM

DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM modules rather than 168-pin DIMM modules used by SDR SDRAM. High memory bandwidth makes DDR an ideal solution for high performance PC, workstations and servers.

2-6

Hardware Setup

DDR DIMM Module Combination

Install at least one DIMM module on the slots. Memory modules can be installed on the slots in any order. You can install either single- or doublesided modules to meet your own needs.

Memory modules can be installed in any combination as follows:

Slot Memory Module Total Memory

DIMM 1 (Bank 0 & 1) DIMM 2 (Bank 2 & 3) DIMM 3 (Bank 4 & 5)

Maximum System Memory Supported

64MB~3GB

Installing DDR Modules

1. The DDR DIMM has only one notch on the center of module. The module

will only fit in the right orientation.

2. Insert the DIMM memory module vertically into the DIMM slot. Then

push it in until the golden finger on the memory module is deeply inserted in the socket.

You can barely see the golden finger if the module is properly inserted in the socket.

3. The plastic clip at each side of the DIMM slot will automatically close.
