FCC-B Radio Frequency Interference Statement

This equipment has been tested and found to comply with the limits for a class
B digital device, pursuant to part 15 of the FCC rules. These limits are designed
to provide reasonable protection against harmful interference when the equip­ment is operated in a commercial environment. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accor­dance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference, in which case the user will be required to correct
the interference at his own expense.

Notice 1

The changes or modifications not expressly approved by the party respon­sible for compliance could void the user’s authority to operate the equipment.

Notice 2

Shielded interface cables and A.C. power cord, if any, must be used in order to
comply with the emission limits.

PC Alert™ III

The PC AlertTM III is a utility you can find in the CD-ROM disk. The
utility is just like your PC doctor that can detect the following PC hardware
status during real time operation:

* monitor CPU & system temperatures

* monitor fan speed(s)

* monitor system voltage

* monitor chassis intrusion

If one of the items above is abnormal, the program main screen will be
immediately shown on the screen, with the abnormal item highlighted in red.
This will continue to be shown,until user disables the warning.

Note: Items shown on PC Alert III vary depending on your system’s

status.

D-Bracket™ & D-LED™ (Optional)

The D-LED™ uses graphic signal display to help us­ers understand their system. Four LEDs embedded in the
mainboard provide up to 16 combinations of signals to de­bug the system. The 4 LEDs can debug all problems that
fail the system, such as VGA, RAM or other failures. This
special feature is very useful for the overclocking users.
These users can use the feature to detect if there are any
problems or failures.

The D-Bracket™ which integrates four Diagnostic LEDs is optional.
Definitions of the D-Bracket™ LED signals are the same as D-LED™ as shown
below.

Live BIOS™/Live Driver™

The Live BIOSTM is a tool used to detect and update your
BIOS online so that you don’t need to search for the correct
BIOS version through the whole web site. To use the function,
you need to install the “MSI Live Update Series” application.
After installation, the “MSI Live Update Series” icon (as the
right view) will appear on the screen.

Double click the “MSI Live Update Series” icon, and the following screen
will appear.

Four buttons are placed on the left column of the screen. Click the desired
button to start the update process.

Hardware Setup

This chapter provides you with the information about hardware setup
procedures. While doing the installation, be careful in holding the components
and follow the installation procedures. For some components, if you install in
the wrong orientation, the components will not work properly.

Use a grounded wrist strap before handling computer components. Static
electricity may damage the components.

1. Pull the lever sideways away

from the socket. Then, raise
the lever up to a 90-degree
angle.

2. Look for the dot/cut edge. The

dot/cut edge should point to­wards the lever pivot. The
CPU will only fit in the correct
orientation.

3. Hold the CPU down firmly,

and then close the lever to
complete the installation.

The mainboard supports Intel® Pentium® 4 processor in the 478 pin
package. The mainboard uses a CPU socket called PGA478 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.

Overheating will seriously damage the CPU and system,
always make sure the cooling fan can work properly to
protect the CPU from overheating.

WARNING!

Installing the CPU Fan

As processor technology pushes to faster speeds and higher
performance, thermal management becomes increasingly important. To dissi­pate heat, you need to attach the CPU cooling fan and heatsink on top of the
CPU. Follow the instructions below to install the Heatsink/Fan:

2. Position the heatsink onto the reten-

tion mechanism.

1. Locate the CPU and its retention

mechanism on the motherboard.

3. Mount the fan on top of the heatsink.

Press down the fan until its four clips
get wedged in the holes of the reten­tion mechanism.

4. Press the two levers down to fasten

the fan. Each lever can be pressed
down in only ONE direction.

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
= 1.4GHz

5. Connect the fan power cable from the mounted fan to the 3-pin fan power connector

on the board.

Overclocking

This motherboard is designed to support overclocking.
However, please make sure your components are able to
tolerate such abnormal setting, while doing overclocking.
Any attempt to operate beyond product specifications is not
recommended. We do not guarantee the damages or risks

caused by inadequate operation or beyond product
specifications.

Memory

The mainboard supports a maximum memory size of 3GB. It provides

three 168-pin unbuffered SDRAM DIMM (Double In-Line Memory Module)
sockets and supports 64MB to 512MB technology.

Introduction to SDR SDRAM

Synchronous DRAM is a type of dynamic RAM memory chip that has
been widely used starting in the latter part of the 1990s. SDRAMs are based on
standard dynamic RAM chips, but have sophisticated features that make them
considerably faster. First, SDRAM chips are fast enough to be synchronized
with the CPU's clock, which eliminates wait states. Second, the SDRAM chip is
divided into two cell blocks, and data is interleaved between the two so that
while a bit in one block is being accessed, the bit in the other is being prepared
for access. This allows SDRAM to burst the second and subsequent, contigu­ous characters at a rate of 10ns, compared to 60ns for the first character.

SDRAM provides 800 MBps or 1 GBps data transfer depending on
whether the bus is 100MHz or 133MHz.

Note: As Intel® 845 chipset does not properly support the PC100
memory, it is strongly recommended that users install PC133 DIMM
modules for better system performance and stability. We do not guar­antee the system stability when installing PC 100 DIMM modules.

1. The DIMM slot has 2 Notch Keys “VOLT and DRAM”, so the
DIMM memory module can only fit in one direction.

2. Insert the DIMM memory module vertically into the DIMM slot.
Then push it in.

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

Power Supply

A TX 20-Pin Power Connector: JWR1

This connector allows you to connect to an ATX power supply. To
connect to the ATX power supply, make sure the plugs of the power supply is
inserted in the proper orientation and the pins are aligned. Then push down
the power supply firmly into the connector. The power connector supports
instant power on function which means that system will boot up immediately
when the power supply connector is inserted on the board.

The mainboard supports ATX power supply for the power system. Be­fore inserting the power supply connector, always make sure that all compo­nents are installed properly to ensure that no damage will be caused.

A TX 12V Power Connector: JPW1

This 12V power connector is used to provide power to the CPU.
