Mainboard Setup

This chapter provides you with the information about hard-
ware 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®PentiumTM 4 processors (Willimate
478andNorthwood478). 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, al-
ways 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 sup-
ply or unplug the power supply’s power cord from grounded
outlet first to ensure the safety of CPU.

CPU Installation Procedures
1. Turn off the power and unplug
the power cord before install-
ing the CPU.
2. Pull the lever sideways away
from the socket. Make sure
to raise the lever up to a 90-
degree angle.
3. Look for the gold arrow. The
gold arrow should point to-
wards 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. PresstheCPUdownfirmlyinto
the socket and close the lever.
As the CPU is likely to move
while the lever is being
closed, always close the le-
ver with your fingers press-
ing tightly on top of the CPU
to make sure the CPU is prop-
erly and completely embed-
ded into the socket.

The CPU cooler included in the packing is designed specially for MS-
6243 barebone. It is different from other CPU cooler of PentiumTM4. See the
follows for the features:
zCopper Material
The heatsink is made of copper that has better heat-disseminating effect.
zShockproof Effect
The cooler has good shockproof effect through the mechanical combi
nation design of CPU fan and heatsink.
zSmall Size
Contrast to normal CPU cooler, the small size takes up less space.
zSpecial Fan Design
The CPU fan has ball bearing solution. The reliability is better than
sleeve solution. It is suitable for Slim PC.
zHigh 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 de-
signed for shockproof. While
securing the cooler, the front
part of screw can not be em-
bedded into the hole
completely.
