Hardware Setup

Central Processing Unit: CPU

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.

CPU Core Speed Derivation Procedure

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

For example:

If CPU Clock

Core/Bus ratio

then CPU core speed =

=

Hardware Setup

Memory

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 DDR333/DDR266/DDR200 modules on the DDR

DIMM slots.

DDR DIMM Slots

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.

2-7

MS-6703 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:

Slot Memory Module Total Memory

DIMM 1

(Bank 0 & 1)

DIMM 2

(Bank 2 & 3)

S/D 64MB~1GB

Maximum System Memory Supported 64MB~2GB

S: Single Side D: Double Side

Installing DDR Modules

1.

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

BIOS Setup

Set Supervisor/User Password

When you select this function, a message as below will appear on the screen:

Type the password, up to eight characters in length, and press <Enter>. The password typed now will replace any previously set password from CMOS memory. You will be prompted to confirm the password. Retype the password and press <Enter>. You may also press <Esc> to abort the selection and not enter a password.

To clear a set password, just press <Enter> when you are prompted to enter the password. A message will show up confirming the password will be disabled. Once the password is disabled, the system will boot and you can enter Setup without entering any password.

When a password has been set, you will be prompted to enter it every time 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

Security Option is set to System, the password is required both at boot and at entry to Setup. If set to Setup, password prompt only occurs when you try to enter Setup.
