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

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. High memory
bandwidth makes DDR an ideal solution for high performance PC, worksta­tions and servers.

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.

Y ou 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: JBA T1

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 Data

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.

Slots

The motherboard provides three 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. The slot only supports 4x AGP card.

PCI Slots

Three 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.

Hardware Setup

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#

system from entering power saving modes or awaken it from power sav­ing modes. Setting options: Disabled, Enabled.

Note: IRQ (Interrupt Request) lines are system resources allocated
to I/O devices. When an I/O device needs to gain attention of the
operating system, it signals this by causing an IRQ to occur. After
receiving the signal, when the operating system is ready, the system
will interrupt itself and perform the service required by the I/O device.

RING Power Up Control, PCI PME Power Up Control, USB Port W ake
Up Control, Hot Key Power Up Control, PS2 Mouse Power Up Control

These fields specify whether the system will be awakened from power
saving modes when activity or input signal of the specified hardware
peripheral or component is detected.

Note: T o use the function of “RING Power Up Control”, you need to
install a modem supporting power on function.

KB Power On Password

This setting allows you to enter the password to authorize the keyboard
to power on the system.

Power Up by Alarm

This function is for setting date and time for your computer to boot up.
During Disabled, you cannot use this function. During Enabled, choose
the Month, Day, and Time Alarm:

Month Alarm Y ou can choose which month the system will boot up.
Day of Month Alarm Y ou can choose which day of the preset month

the system will boot up. Set to 0, to boot every
day.

Time (hh:mm:ss) Alarm You can choose what hour, minute and

second the system will boot up.

Note: If you have change the setting, you must let the system boot up
until it goes to the operating system, before this function will work.

PNP/PCI Configurations

This section describes configuring the PCI bus system. 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
own 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.

Reset Configuration Data

Normally, you leave this field Disabled. Select Enabled to reset Extended Sys­tem Configuration Data (ESCD) when you exit Setup if you have installed a
new add-on and the system reconfiguration has caused such a serious conflict
that the operating system can not boot. The settings are: Enabled and Disabled.

Resource Controlled By

The A ward 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.

IRQ Resources

The items are adjustable only when Resources Controlled By is set to Manual.

BIOS Setup

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 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. Monitor function is available only if there is hardware monitoring
mechanism onboard.

CPU Warning T emperature

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 T emperature, 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. T o be able to clear
those warnings, choose Reset. After clearing the message it will go back to
Enabled.

Shutdown Temperature

This option is for setting the shutdown temperature level for the processor.
When the processor reaches the temperature you set, the ACPI-aware system
will be shut down.

Frequency/Voltage Control

This section describes how to set the CPU FSB frequency, spread spectrum,
clock ratio etc.

CPU Clock Ratio

End users can overclock the processor by specifying the CPU ratio (clock
multiplier) in this field.

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 be­cause even a slight jitter can introduce a temporary boost in clockspeed which
may just cause your overclocked processor to lock up.

CPU Host/SDRAM/PCI Clock

This setting controls the clock speed of the CPU Host (FSB)/SDRAM memory
bus/PCI bus on the motherboard.

BIOS Setup

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.

T o 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 P ASSWORD CHECK option of the ADV ANCED BIOS
FEATURES menu. If the PASSWORD CHECK option is set to Always, 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.
