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 Installation Procedures
1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
2. Look for the dot/cut edge. The
dot/cut edge should point towards the lever pivot. The
CPU will only fit in the correct
orientation.
3. Hold the CPU down firmly, and
then close the lever to
complete the installation.

CPU Core Speed Derivation Procedure
If CPU Clock = 100MHz
Core/Bus ratio = 14
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHz x 14
= 1.4GHz
Overclocking
This motherboard is designed to support overclocking.
WARNING!
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.

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. Two types of
DDR are available at the time of writing: PC1600 & PC2100. PC1600 DDR SDRAM
running at 100MHz will produce about 1.6GB/s memory bandwidth. PC2100
running at 133MHz will produce 2.1GB/s memory bandwidth. High memory
bandwidth makes DDR an ideal solution for high performance PC, workstations and servers.

Chapter 2
DDR Module Combination
You can install either single sided or double sided 184-pin DDR DIMM
modules into DDR DIMM slots to meet your needs. Different from the SDR
DIMM, the DDR DIMM has only one notch on the center of module. The
number of pins on either side of the breaks are different. The module will only
fit in the right orientation.
You can install memory modules in any combination as follows:

Jumpers
The motherboard provides one jumper for you to set the computer’s
function. This section will explain how to change your motherboard’s function
through the use of the jumper.
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:

Clear CMOS
You can clear CMOS by shorting 2-3 pin while the
system is off. Then return to 1-2 pin position. Avoid
clearing the CMOS while the system is on; it will
damage the mainboard.

Hardware Setup
Slots
The motherboard provides five 32-bit Master PCI bus slots, one AGP
slot and one CNR slot.
AGP Slot
PCI Slots
CNR Slot
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 three levels of throughputs: 1x (266Mbps),
2x (533Mbps) and 4x (1.07Gbps).
PCI Slots
Five 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.
CNR (Communication Network Riser)
The CNR slot allows you to insert the CNR expansion cards. CNR is a
specially designed network, audio, or modem riser card for ATX family
motherboards. Its main processing is done through software and controlled by
the motherboard’s chipset.

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 A# INT B# INT C# INT D#
PCI Slot 2 INT B# INT C# INT D# INT A#
PCI Slot 3 INT C# INT D# INT A# INT B#

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

PC Health Status
This section shows the status of your CPU, fan, warning for overall system
status.
CPU Warning Temperature
If the CPU temperature reaches the upper limit preset in this setting, the warning mechanism will be activated. This helps you to prevent the CPU overheat
problem.
Current System/CPU Temperature, CPU/System Fan, Vcore, 3.3V, +5V, +12V,
-12V, -5V, 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.
Chassis Intrusion Detect
Set this option to enable, reset, or disable the chassis intrusion detector. During Enabled, any intrusion on the system chassis will be recorded. The next
time you turn on the system, it will show a warning message. To be able to clear
those warnings, choose Reset. After clearing the message it will go back to
Enabled.

Frequency/Voltage Control
This section describes how to set the Chassis Intrusion feature, CPU FSB
frequency, monitor the current hardware status including CPU/system
temperatures, CPU/System Fan speeds, Vcore etc. Monitor function is available only if there is hardware monitoring mechanism onboard.
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, setting to Enabled for EMI
reduction. Remember to disable Spread Spectrum if you are overclocking be-

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.

Set Supervisor/User Password
When you select this function, a message as below will appear on the screen:
Type the password, up to six 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 AMIBIOS 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 Features
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.
About Supervisor Password & User Password:
Supervisor password: Can enter and change the settings of
the setup menu.
User password: Can only enter but do not have the right
to change the settings of the setup menu.
