To Get things ready for hardware setup !

1. We recommend to install your CPU before any other components.

For detailed installation instructions of processor, you can also refer
to the pamphlet enclosed in your CPU package.

2. Installing a cooling fan with a good heatsink is a must for proper heat

dissipation for your CPU. Get ready an appropriate fan with heatsink
for proper installation. Improper fan and installation will damage your
CPU.

3. In case CPU Vcore, CPU clock or Frequency Ratio is adjustable on

board, please follow the instructions described in the User Manual
for proper setup. Incorrect setting will cause damage to your CPU.

Intel

pentium 4

2.4 GHz / 512 / 533 / 1.5V

(Hyper-threading CPUs included)

4. CPU Voltage Vcore

3. System Clock

2. CPU L2 Cache

1. CPU Working Frequency

On the heatsink side of a Pentium 4 CPU, there printed a line of figures
to identify its specifications. The line consists of 4 parts:

1. CPU Working Frequency: this part depicts the working frequency of
the CPU. For example,

2.4 GHz depicts that this CPU is locked to 2.4 GHz working frequency
(18 x 133MHz CPU clock);
2A GHz depicts that this CPU is an A version, locked to 2.0 GHz
working frequency (20 x 100MHz CPU clock)

3.06GHz depicts that this is a 3.06GHz hyper-threading CPU.

2. CPU L2 Cache: This part depicts the L2 Cache size. For example,
512 stands for 512 KB L2 Cache; 256 stands for 256 KB L2 Cache

3. System Clock: this part depicts the System Clock (Front Side Bus)
provided by the CPU. For example,
533 stands for a 533MHz system clock provided by a 133MHz CPU
times 4;
400 stands for a 400 system clock provided by a 100 MHz CPU x 4.

4. CPU Voltage Vcore: this part depicts the CPU Voltage. For example,

1.5V stands for a CPU of 1.5V Vcore.
Note: System Clock vs CPU Clock

P4 CPU is a quadpumped CPU. The system bus is provided by the
CPU clock x 4. Therefore, users can figure out the P4 CPU clock by the
System Clock divided by 4.

2-1.2 CPU Installation with Socket 478B

This mainboard is built with CPU
Socket 478B ( 478-pin) supporting
the Intel Pentium 4 CPU:

• Follow the steps described in this
section to install the 478-pin Pen­tium 4 CPU into the on board
Socket 478.

• After installation of Pentium 4 CPU,
you must also install the specific
Pentium 4 CPU fan designed in
tandem with this CPU. This CPU
Fan installation is described in next
section.

• This mainboard supports Hyper­threading dual-in-one CPU, the
function of which can be enabled
by Windows XP. (See illustration
on the right.)

1. First pull sideways the lever of
Socket 478, and then turn it up

0

so as to raise the upper layer

90
of the socket from the lower
platform.

( If Hyper-threading CPU is
installed successfully with O/S
Win XP, the O/S will enable the
dual-in-one CPU function.)

mPGA478B

Pin 1

2. Configure Pin 1 of CPU to Pin 1
of the Socket, just as the way
shown in the diagram on the
right. Adjust the position of CPU
until you can feel all CPU pins
get into the socket with ease.

3. Make sure that all CPU pins have
completely entered the socket
and then lower down the lever
to lock up CPU to socket.

2-3 Memory Installation

How to tackle the memory Modules:

• Make sure to unplug your power supply before adding or removing
memory module. Failure to do so may cause severe damage to both
your mainboard and the memory module.

• Pay attention to the orientation of the DIMM slots. Forcing a DIMM
into a slot improperly will damage the memory module and slot itself.

• Make sure you have the right type of memory module for your
mainboard.

2-3.1 To Install DDR SDRAM Module

• This series only supports up to 2GB unbuffered DDR 266/200 SDRAM,
with 2 DDR DIMM slots on board. Do not insert other type of mod­ules into these slots.

• DDR DIMM slot has 184-pins and one notch. Insert a DDR SDRAM
vertically into the 184-pin slot with the notch-to-rib matching. Press
the Module down in a gradual way until it surely reaches the bottom
and clicks straight up the two latches on the left and right of the slot.
If any one of the latches has not turned up completely, you should
unplug the module and press it down a bit more firmly.

ATX V2.03 power supply is strongly recommended for mainboard run­ning with 2GHz or higher CPU.

To set up Power Supply on this mainboard:

1. Connect the on-board Main Power Connector (20-pin) to the Main
Power Connector (20-pin) of an ATX Power Supplier which can be
either of the latest version 2.03 or of earlier ATX format.

2. If you use an ATX Power Supply Version 2.03 or later, you can now
connect the on-board square-shaped +12V Connector to the square­shaped +12V Connector of your ATX Power Supplier. In this case, it
is not necessary for you to connect the on-board 4-pin Peripheral
Power Connector to your Power Supplier.

3. If you use an ATX power Supplier of an older version than V2.03, you
cannot find a square-shaped +12V Connector with your Power
Supplier; you must then connect the on-board 4-pin Peripheral Power
Connector to the 4-pin Peripheral Power Connector of your Power
Supplier.

2-8.1 How to tackle the Jumpers:

123

A 3-pin Jumper

If a pin-header (of 2 or more pins) is
designed in such a way that its pins
can be closed or linked together to
set up a specific function,
is called a jumper in this manual.

this header

A 2-pin
Jumper
Cap

The conductor inside the cap
links two header-pins together.

• A Jumper is usually but not necessarily given a “JpX” legend.

• In the Jumper setting diagram, the jumper pins covered with
black marks stand for closed pins with jumper cap.

Jp X

Jumper with

Jumper with

Pin 1-2 closed

• Do not remove any jumper cap when power is on. Always
make sure the power is off before changing any jumper settings.
Otherwise, the mainboard will be damaged.

2-8.2 JBAT1: Clear CMOS

When you have problem with rebooting your
system, you can clear CMOS data and restore
it to default value. To clear CMOS with Jumper
JBAT1, please follow the steps below:

1. Power off system;

2. Set JBAT1 to Pin 2-3 closed.

3. After 2 or 3 seconds, return the JBAT1 setting
to Pin1-2 closed.

4. CMOS data are restored to default.
Remember never clear CMOS when system
power is on.

2-8.3 Jp8: CPU Clock/Overclock Select

Jp8 is designed on board as a jumper for CPU clock select and 100MHz
to 133MHz CPU overclocking. With Jp8, user can choose the way for a
100MHz CPU to run an overclock on board.

1. Before setting the CPU clock, read the Identification Legend on the
CPU, find the Max FSB and divide it by two. The result is the default
CPU clock of your CPU.

2. If Jp8 is set to 1-2 closed, CPU clock will
be autodetected by BIOS, indicating that
overclock is not desired. The CPU will boot
system with the default CPU clock on the
CPU you use.

3. If Jp8 is set to 2-3 closed, CPU is set to
133MHz CPU clock, indicating that 133MHz
overclock is desired. The CPU will try to
boot system with 133MHz even if a 100MHz
CPU is used.

However, if overclok fails, system will fail

to boot. In such case, restore Jp8 to default
setting and clear CMOS by jumper before
restarting system.

Notes on CPU Overclocking:

1. If you have successfully booted system with or without CPU overclock,
you still can do another CPU overclock in BIOS Setup. Please enter
BIOS Setup, choose “Frequency/Voltage Control” menu, and take
the “Use Linear” option of the “Use CPU Linear Frequency”. Then
configure the “CPU Clock” item to raise your CPU clock.

2. CPU overclocking should take all components on board into account.
If you fail in BIOS overclocking, you will not be able to restart system.
In such case, power off system and clear CMOS by JBAT1 as stated
below and then restart your system. And remember to reconfigure
whatever should be reconfigured.

3. If your system is already fixed in a cabinet or case, you may not like
to take the trouble to clear CMOS. Then power on your system with
the power button on the case and simultaneously press down the
“Insert” key on the keyboard until you see the initial bootup screen
appear. And remember you should also enter CMOS BIOS Setup
and choose “Load Optimized Defaults” to restore default BIOS .

2-8.4 Jp3: KB / Mouse / Power Button Select

Jp3 is designed to select keyboard/Mouse/Power button as the power­on controller. Setting Jp3 to 1-2 closed will allow user to power on sys­tem by power button. Setting Jp3 to 2-3 closed will allow user to power
up system by keyboard/Mouse. Yet user still has to enter BIOS Setup
for choosing the KB/Mouse Power-on mode. (See Integrated Peripher­als” in BIOS Setup.)

2-8.5 JDIMM1 & JDIMM2: DIMM Voltage Select

The default voltage 2.7V at DIMM sock­ets is for the optimum operation of the
supported DDR SDRAM. In some case,
when you are not doing CPU over­clocking, you may find a lower DIMM volt­age would work better. JDIMM1 &
JDIMM2 are designed on board to pro­vide settings for adjusting the DIMM
voltage so as to optimize the operation
stability.

2-8.6 JAGP1 & JAGP2: AGP Voltage Select

The default voltage 1.5V at the whole AGP Interface is for normal op­eration of the AGP interface. In some case, when you try to do CPU
overclocking, you then may also need to raise the transfer rate of the
AGP interface. JAGP1 & JAGP2 are designed on board to provide
settings for selecting a higher AGP Interface voltage so as to raise the
speed of the AGP interface.

Warning: Selecting a higher voltage than the default ,
you are risking the stability of your system.

These fan connectors support CPU/AGP/System cooling fan with
+12V. When connecting the wire to FAN connectors, users should make
sure that the red wire is for the positive current and should be con­nected to pin +12V, and the black wire is Ground and should be con­nected to pin GND. If your mainboard has Hardware Monitor chipset on
board, you must use a specially designed fan with speed sensor to take
advantage of the monitoring function.

For fans with speed sensors, each rotation of the fan blades will send
out 2 electric pulses, By counting the pulses, System Hardware Moni­tor will work out the fan rotation speed and display the result on the
scree.

NOTE : 3 “Yellow” fan connectors are used on this series to mark that
they support fan speed sensor function. (White fan connector does not
support sensor function.)

To Devices

1. Connector RT2: A thermal resistor is mounted by default to connector

RT2 so as to detect the temperature of the CPU. What RT1 does is
to transmit the thermal signal to BIOS or Hardware Monitor.

2. Connector Jp11: A thermal cable is needed to connect Jp11 to on-

board devices such as HDD, Graphics card etc., so as to detect the
temperature generated therein. Please connect the end (a) of the
thermal cable to Jp11, and tape another end (b) of thermal cable on
to the device which you want to monitor. After you have finished the
thermal cable installation, you will see the detected temperature in

BIOS setup or Hardware Monitor utility.

• Both ISA and PCI expansion cards may require IRQs. System IRQs are

available to cards installed in the ISA expansion bus first, then any remain-

ing IRQs are available to PCI cards. Currently, there are two types of ISA

cards.

• The original ISA expansion card design, now referred to as “Legacy” ISA

card, requires you to configure the card’s jumpers manually and then install

it in any available slot on the ISA bus. To see a map of your used and free

IRQs in Windows 98, the Control Panel in My Computer, contains a Sys-

tem icon, which gives you a Device Manager tab. Double-Clicking on a

specific hardware device gives you a Resources tab which shows the In-

terrupt number and address. Double-Clicking Computers to see all the in-

terrupts and addresses for your system. Make sure that each ISA device

should be assigned to one IRQ respectively. If ISA device share IRQ with

any other device, your computer will easily get into trouble.

Chapter 4 AMI BIOS Setup

THE BIOS

BIOS stands for Basic Input and Output System. It was once called
ROM BIOS when it was stored in a Read-Only Memory (ROM) chip
Now manufacturers would like to store BIOS in EEPROM which means
Electrically Erasable Programmable Memory. BIOS used in this series
of mainboard is stored in EEPROM, and is the first program to run when
you turn on your computer.

BIOS performs the following functions:

1. Initializing and testing hardware in your computer (a process called
“POST”, for Power On Self Test).

2. Loading and running your operating system.

3. Helping your operating system and application programs manage
your PC hardware by means of a set of routines called BIOS Run­Time Service.

This Chapter includes the following topics :
4-1 About BIOS Setup
4-2 To Run BIOS Setup
4-3 About CMOS
4-4 The POST (Power On Self Test)
4-5 To Update BIOS
4-6 BIOS Setup

2. Modifying the behavior of your computer. (For example: changing
the system time or date, or turning special features on or off etc.)

3. Enhancing your computer’s behavior. (For example: speeding up
performance by turning on shadowing or cache)

4-2 To Run BIOS Setup

First access BIOS setup menu by pressing < DEL > key after “POST” is
complete ( before OS is loaded ). BIOS will then display the following
message:

DEL:SETUP

4-3 About CMOS

CMOS is the memory maintained by a battery. CMOS is used to store
the BIOS settings you have selected in BIOS Setup. CMOS also
maintains the internal clock. Every time you turn on your computer, the
BIOS Looks into CMOS for the settings you have selected and configures
your computer accordingly. If the battery runs out of power, the CMOS
data will be lost and POST will issue a “CMOS invalid” or “CMOS
checksum invalid” message. If this happens, you have to replace the
battery and check and configure the BIOS Setup for the new start.

4-4 The POST ( Power On Self Test )

POST is an acronym for Power On Self Test. This program will test all
things the BIOS does before the operating system is started. Each of
POST routines is assigned a POST code, a unique number which is
sent to I/O port 080h before the routine is executed.

4-5 To Update BIOS

• System BIOS is incorporated into a Flash memory component. Flash

BIOS allows user to upgrade BIOS without the need to replace an EPROM
component.

• The Upgrade Utility can be loaded on a floppy diskette for upgrading

saving, and verifying the system BIOS. The Update Utility can also be
run from a hard disk drive or a network drive.

• It is highly recommended that you save a copy of the original mainboard

BIOS along with a Flash EPROM Programming utility (AMIXXX.EXE)to a
bootable floppy disk so that you can reinstall the BIOS when in need.

• Normally, to update BIOS is unnecessary if the system is working fine.

Users should only update BIOS when incompatible problems are encoun­tered or new features have to be added to system.

• “AMIFLASH.EXE” is a Flash EPROM Programming utility that updates

the BIOS by uploading a new BIOS file to the programmable flash ROM
on the mainboard. This program only works in DOS environment, the

utility can not be executed in win95/98, ME, NT WINDOWS 2000 or
Windows XP environment.

• Please follow the steps below for updating the sys­ tem BIOS:

Step 1. Please visit the board maker’s website, download latest BIOS
file and AMI update utility. The file name of AMI update utility will be
“AMIXXX.EXE” of which “ XXX ” stands for the version number of the
file. The BIOS file format will be *.ROM, of which “ * ” stands for the
specific BIOS file name.

Step 2. Create a bootable diskette. Then copy the BIOS file and AMI
flash utility “AMIXXX.EXE” into the diskette.

Step 3. Insert the diskette into drive A, boot your system from the
diskette.

58

Chapter 4 BIOS Setup

Step 4. Under “ A “ prompt, type “ AMIXXX.EXE *.ROM “ and then
press <Enter> to run BIOS update program. Please note that there
should be a space between AMIXXX.EXE and *.ROM. (*.ROM depends
on your mainboard model and version code. Instead of typing “*”, you
should type the specific file name for your specific mainboard).
Example: A:\AMI2.exe(1 space)85DIV05.ROM

Step 5. When the message “Flash ROM Update Completed - Pass.”
appears, please restart your system.

Step 6. You will see a message “CMOS Memory Size Wrong” during
booting the system. Press <Del> or <F1> to run CMOS setup utility,
then reload “LOAD SETUP DEFAULTS” or “Load Optimal Defaults”
and save this change.
