Hardware Setup

Central Processing Unit: CPU

The mainboard supports Intel® Pentium® 4/Celeron Northwood/Prescott
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.

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

MS-6743G M-ATX Mainboard

CPU Installation Procedures for Socket 478

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.

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.

MS-6743G 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.

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.

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:

PNP/PCI Configurations

This section describes configuring the PCI bus system and PnP (Plug & Play)
feature. PCI, or Peripheral Component Interconnect, is a system which al­lows I/O devices to operate at speeds nearing the speed the CPU itself uses
when communicating with its special components. This section covers some
very technical items and it is strongly recommended that only experienced
users should make any changes to the default settings.

PNP OS Installed

When set to [Yes], BIOS will only initialize the PnP cards used for booting
(VGA, IDE, SCSI). The rest of the cards will be initialized by the PnP oper­ating system like Windows 98. When set to [No], BIOS will initialize all the
PnP cards. So, select [Yes] if your operating system is Plug & Play aware.

Resource Controlled By

The Award Plug and Play BIOS has the capacity to automatically configure
all of the boot and Plug and Play compatible devices. However, this capability
means absolutely nothing unless you are using a Plug and Play operating sys­tem such as Windows® 95/98. If you set this field to “manual” choose specific
resources by going into each of the sub menu that follows this field (a sub
menu is preceded by a “¾”). The settings are: Auto (ESCD), Manual.

BIOS Setup

IRQ Resources

The items are adjustable only when Resources Controlled By is set to Manual.
Press <Enter> and you will enter the sub-menu of the items. IRQ Resources
list IRQ 3/4/5/7/9/10/11/12/14/15 for users to set each IRQ a type depending
on the type of device using the IRQ. Settings are:

PCI Device For Plug & Play compatible devices designed for PCI

bus architecture.

Reserved The IRQ will be reserved for further request.

PCI/VGA Palette Snoop

When set to Enabled, multiple VGA devices operating on different buses can
handle data from the CPU on each set of palette registers on every video
device. Bit 5 of the command register in the PCI device configuration space is
the VGA Palette Snoop bit (0 is disabled). For example, if there are two VGA
devices in the computer (one PCI and one ISA) and the:

VGA Palette Snoop

Bit Setting

Disabled Data read or written by the CPU is only directed to the PCI

VGA device’s palette registers.

Enabled Data read or written by the CPU is directed to both the PCI

VGA device’s palette registers and the ISA VGA device’s
palette registers, permitting the palette registers of both VGA
devices to be identical.

Action

The setting must be set to Enabled if any ISA bus adapter in the system re­quires VGA palette snooping.

INT Pin 1~8 Assignment

The items allow you to assign an IRQ line to INT Pin #1~8 separately. Select­ing Auto allows BIOS to determine the appropriate IRQ for each INT pin.
Options: Auto, 3, 4, 5, 7, 9, 10, 11, 12, 14, 15.

This option allows you to enable/disable the feature of auto detecting the clock
frequency of the installed PCI bus. The settings are: Enabled, Disabled.

Spread Spectrum

When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference). The Spread Spec­trum function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are reduced to flatter curves. If you do not have any EMI
problem, leave the setting at Disabled for optimal system stability and
performance. But if you are plagued by EMI, activate the Spread Spectrum
for EMI reduction. Remember to disable Spread Spectrum if you are
overclocking because even a slight jitter can introduce a temporary boost in
clockspeed which may just cause your overclocked processor to lock up.
Options: Disabled, Enabled.

you try to enter Setup. This prevents an unauthorized person from changing
any part of your system configuration.

Additionally, when a password is enabled, you can also have BIOS to request
a password each time the system is booted. This would prevent unauthorized
use of your computer. The setting to determine when the password prompt is
required is the Security Option of the Advanced BIOS Feature menu. If the
