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 AC. power cord, if any, must be used in order to
comply with the emission limits.

Mainboard Setup

This chapter provides you with the information about hard­ware setup procedures for MS-6557 mainboard. 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.

Mainboard Setup

Chapter 2

2-2

The mainboard supports Intel® Pentium

TM

4 processors (Willimate

478 and Northwood 478). The mainboard uses a CPU socket called Socket 478

for easy CPU installation. While 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 or purchase them
before installing the CPU.

Central Processing Unit: CPU

Overheating

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

Replacing the CPU

While replacing the CPU, always turn off the ATX power sup­ply or unplug the power supply’s power cord from grounded
outlet first to ensure the safety of CPU.

Mainboard Setup

2-3

CPU Installation Procedures

1. Turn off the power and unplug

the power cord before install­ing the CPU.

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.

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 CPU cooler included in the packing is designed specially for MS­6243 barebone. It is different from other CPU cooler of PentiumTM4. See the
follows for the features:

z Copper Material

The heatsink is made of copper that has better heat-disseminating effect.

z Shockproof Effect

The cooler has good shockproof effect through the mechanical combi

nation design of CPU fan and heatsink.

z Small Size

Contrast to normal CPU cooler, the small size takes up less space.

z Special Fan Design

The CPU fan has ball bearing solution. The reliability is better than

sleeve solution. It is suitable for Slim PC.

z High Density Fan Fins

The CPU cooler has high density fan fins than normal CPU cooler. It is

ideal for heat disseminating.

Attaching CPU Cooler

2. Use 4 screws to secure

the CPU cooler.

1. Put the CPU cooler on the CPU.

* The four screws of CPU cooler
are built-in.

* The front part of screw is de­signed for shockproof. While
securing the cooler, the front
part of screw can not be em­bedded into the hole
completely.

Mainboard Setup

The mainboard provides two sockets for 184-pin DDR SDRAM DIMM
(Double In-Line Memory Module) and supports the memory size up to 2 GB.
You can install PC2100/DDR266 or PC1600/DDR200 modules into the DDR
DIMM slots.

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. T wo types of
DDR are available at the time of writing: PC1600 & PC2100. PC1600 DDR SDRAM
running at 100MHz will produce about 1.6GB/s memory bandwidth. PC2100
running at 133MHz will produce 2.1GB/s memory bandwidth. High memory
bandwidth makes DDR an ideal solution for high performance PC, worksta­tions and servers.

This connector allows you to connect to an ATX power supply. To
connect to the ATX power supply , make sure the plug 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.

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

*T.M.D.S. Technology
The graphics data sent to the digital monitor use Transition Minimized
Differential Signaling (T.M.D.S.) technology. TMDS uses an encoding
algorithm to 8-bit of data into a 10-bit transition minimized, DC balanced
character, which are transition-minimized to reduce EMI with copper
cables and DC-balanced for transmission over fiber optic cables. The
TMDS algorithm also provides robust clock recovery for greater skew
tolerance with longer cables or low cost short cables.
