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

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.

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:

This item is used to specify a thermal limit for CPU. If CPU temperature
reaches the specified limit, the system will issue a warning which allows you
to prevent the CPU overheat problem. Settings: Disabled, 50oC/122oF, 53oC/
127oF, 56oC/133oF, 60oC/140oF, 63oC/145oF, 66oC/151oF and 70oC/158oF.
System/CPU Temperature, System/CPU FAN Speed, Vcore, 3.3V, +5V,
+12V, -12V, VBAT(V), 5VSB(V)
These items display the current status of all of the monitored hardware devices/components such as CPU voltages, temperatures and all fans’ speeds.
Shutdown Temperature
When the processor reaches the preset temperature, the ACPI-aware system
will be shut down. Settings: Disabled, 60oC/140oF, 65oC/149oF, 70oC/158oF,
75oC/167oF.

BIOS Setup
Frequency/Voltage Control
Use this menu to specify your settings for frequency/voltage control.
CPU Clock Ratio
This setting controls the multiplier that is used to determine the internal clock
speed of the processor relative to the external or motherboard clock speed.
Auto Detect DIMM/PCI Clk
This option allows you to enable/disable the feature of auto detecting the clock
frequency of the installed DIMM/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, +/-0.25%, +/-0.30%, +/-0.35%, +/-0.40%.
CPU Frequency
Use this item to select the appropriate frequency for your CPU FSB. Options
are: Default, 100MHz, 133MHz.

MS-6703 M-ATX Mainboard
Load Fail-Safe/Optimized Defaults
The two options on the main menu allow users to restore all of the BIOS
settings to the default Fail-Safe or Optimized values. The Optimized Defaults
are the default values set by the mainboard manufacturer specifically for optimal performance of the mainboard. The Fail-Safe Defaults are the default
values set by the BIOS vendor for stable system performance.
When you select Load Fail-Safe Defaults, a message as below appears:
Pressing Y loads the BIOS default values for the most stable, minimal
system performance.
When you select Load Optimized Defaults, a message as below appears:
Pressing Y loads the default factory settings for optimal system
performance.

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.
