Setup

This chapter tells you how to install the CPU, memory
modules, and expansion cards, as well as how to setup the jump­ers on the mainboard. Also, it provides the instructions on con­necting the peripheral devices, such as the mouse, keyboard,
etc.

While doing the installation, be careful in holding the com­ponents and follow the installation procedures.

Central Processing Unit: CPU

CPU Core Speed Derivation Procedure

CPU Clock multiplied by Core/Bus ratio equals the CPU core speed.

For example:
If CPU Clock = 100MHz

Core/Bus ratio = 14

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

= 100MHz x 14
= 1.4 GHz

The mainboard supports Intel® Pentium® 4/Celeron 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.

2-4

MS-6575 M-ATX Mainboard

1. Please 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 cut edge. The cut
edge 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.

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.

MS-6575 M-ATX Mainboard

Note:

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.

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.

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

on the board.

Hardware Setup

The mainboard provides 2 slots for 184-pin DDR SDRAM DIMM
(Double In-Line Memory Module) modules and supports the memory size up
to 2GB. You can install PC2700/DDR333 or PC2100/DDR266 modules on
the DDR DIMM slots (DDR 1~2).

DDR DIMM Slots

(DDR 1~2)

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, and
requires 184-pin DIMM modules. High memory bandwidth makes DDR an
ideal solution for high performance PC, workstations and servers.

2-8

MS-6575 M-ATX Mainboard

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:

Installing DDR Modules

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

ule 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.

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

Hardware Setup

The motherboard provides the following jumpers for you to set the
computer’s function. This section will explain how to change your
motherboard’s function through the use of jumpers.

Jumpers

Clear CMOS Jumper: JBAT1

There is a CMOS RAM on board that has a power supply from external
battery to keep the data of system configuration. With the CMOS RAM, the
system can automatically boot OS every time it is turned on. That battery has
long life time for at least 5 years. If you want to clear the system configuration,
use the JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instructions
below to clear the data:

Note:

To clear CMOS, first make the #2-3 pin short connected after the
system is off. And then power on the system and short connect
#1-2 pin before entering the BIOS (Standard CMOS Features) to
clear data.

Hardware Setup

Slots

AGP (Accelerated Graphics Port) Slot

The AGP slot allows you to insert the AGP graphics card. AGP is an
interface specification designed for the throughput demands of 3D graphics.
It introduces a 66MHz, 32-bit channel for the graphics controller to directly
access main memory and provides two levels of throughputs: 2x (533Mbps)
and 4x (1.07Gbps).

PCI (Peripheral Component Interconnect) Slots

The PCI slots allow you to insert the expansion cards to meet your needs.
When adding or removing expansion cards, make sure that you unplug the
power supply first. Meanwhile, read the documentation for the expansion card
to make any necessary hardware or software settings for the expansion card,
such as jumpers, switches or BIOS configuration.

The motherboard provides one AGP slot and three 32-bit PCI bus slots.

PCI Interrupt Request Routing

The IRQ, abbreviation of interrupt request line and pronounced I-R-Q,
are hardware lines over which devices can send interrupt signals to the
microprocessor. The PCI IRQ pins are typically connected to the PCI bus INT
A# ~ INT D# pins as follows:

Order 1 Order 2 Order 3 Order 4

PCI Slot 1 INT B# INT C# INT D# INT A#

PCI Slot 2 INT C# INT D# INT A# INT B#

PCI Slot 3 INT D# INT A# INT B# INT C#
