2-1 CPU Identification and Installation

2-1.1 To Identify a Pentium 4 CPU

Intel

pentium 4

2.4 GHz / 512 / 533 / 1.5V

( Including Hyper-threading CPUs)

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 Hyper-

threading 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

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 DRAM Module for this Mainboard

• This Mainboard only supports up to 2GB unbuffered DDR 333/266
DRAM, 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 DRAM
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.

Chapter 2 Hardware Setup

2-4 Install VGA / AGP 4X with LED1 & Jp4 Safeguard

1. To install on-board VGA, please connect your monitor directly to VGA
connector on board. Default Jp4 at 2-3 closed is to assure booting
system with on-board VGA or 1.5V AGP 4X add-on card yet without
safeguard against 3.3V AGP2X card.

That is, if 3.3V AGP 2X card is mistakenly inserted for booting the

*

system, the high voltage will burn the 1.5V circuitry on board. Never
use a 3.3V or an unknow AGP card in this case.

2. To install AGP 4X card on this mainboard, please insert AGP 4X card
into AGP slot and connect your monitor directly to the AGP 4X card.

To assure the use of a correct AGP 4X card of 1.5V, please set Jp4

to 1-2 closed to allow only 1.5V AGP 4X card to boot system. With
Jp4 1-2 closed, safeguard is enabled against AGP 2X card. That is,
system cannot boot with 3.3V AGP 2X card or on-board VGA. In this
case, if user cannot boot with an AGP card inserted in AGP slot, it
indicates that the AGP card is a wrong one. Find a 1.5V AGP 4X card
before booting this system.

3. LED1 is a Warning LED. Whenever the AGP slot is empty, or if a
wrong AGP card is inserted in AGP slot, LED1 will keep lighting up
until a proper installation is done.

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.

1 13313

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.

2-8.1 Jp8: CPU Clock Select

Jp8 is designed on board for CPU frequency select.

1. Setting Jp8 1-2 closed will allow CPU on board to Auto Detect its
own frequency and apply it to the System Bus.

2. Setting Jp8 2-3 closed is for 133 MHz
CPU. 100MHz CPU will fail to boot
herewith.

3. If 100MHz CPU fails to boot system,
you should restore the default setting
and then clear CMOS to reboot your
system. (See Clear CMOS in next
paragraph.)

Chapter 2 Hardware Setup

Further Notes on CPU Overclocking:

1. If you have successfully booted system, with or without CPU
overclock, you still can try another CPU overclock in BIOS Setup.
Please enter BIOS Setup, choose “Frequency/Voltage Control” menu,
and 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 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 PC 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
instantly and choose “Load Optimized Defaults” to restore default
BIOS .

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 LJP1: LAN Controller Select (85MIR2-L only)

LJP1 is a 3-pin jumper for enabling or dis­abling the on-board LAN Controller. Users can
set LJP1 1-2 closed to enable the on-board
LAN Controller so as to set up the LAN driver,
or to set LJP1 2-3 closed to disable the on­board LAN Controller. In such case, users
are free to use an add-on PCI LAN card for
networking.

2-8.4 JAGP1 & JAGP2: AGP Voltage Select

The default voltage 1.5V at AGP slot is
for normal operation of the supported
AGP 4X. In some case, when you try to
do CPU overclocking, you may also
need to raise the voltage of the AGP
card. JAGP1 & JAGP2 are designed

The default voltage 2.5V at DIMM sock­ets is for the optimum operation of the
supported DDR DRAM. In some case,
when you are doing CPU overclocking,
you may find a higher 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.

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

2-8.7 Jp4: VGA/AGP 4X Safeguard

1. Jp4 1-2 closed: Safeguard against
AGP 2X card.

To assure the use of a correct

AGP4X card of 1.5V, please set
Jp4 to 1-2 closed, resulting in that
it will allow only 1.5V AGP 4X card
to boot system. With Jp4 1-2
closed, system even cannot boot
with on-board VGA. In this case, if
users cannot boot with an AGP
card inserted in AGP slot, it
indicates that the AGP card is a
wrong one. The AGP card should
be changed until a 1.5V AGP4X
card is inserted.

2. Jp4 2-3 closed (default) : Boot system with on-board VGA:

Default Jp4 (2-3 closed) is designed to allow booting system with 1.

5V on-board VGA or 1.5V AGP 4X add-on card, yet without safeguard
against AGP2X card.

If 3.3V AGP 2X card is mistakenly inserted for booting the system,

the high voltage will burn the 1.5V circuitry on board. So, never use
a 3.3V or an unknow AGP card in this case.

Both Sensor and No-sensor Fan Connectors support CPU/AGP/Sys­tem/Case cooling fan with +12V mode. Sensor Fan Connector is yellow
in color on board. When connecting the wire to any Fan Connector,
user 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. A Hardware Monitor chipset is on
board, with which user can install a Hardware Monitor Utility and read
the fan speed transmitted from the sensor fan. Otherwise, user can
read the fan speed from the “Hardware Monitor Status” in CMOS BIOS.

A running fan will send out 2 electric pulses per rotation of its fan
blade. A Sensor Fan Connector will count the electric pulses and send
the information to the System Hardware Monitor which in turn will work
out the fan rotation speed and display it on screen.

1. Resistor RT2: A thermal resistor is to be mounted by default to Resistor
RT2 so as to detect the temperature of the CPU. What RT2 does is
to transmit the thermal signal to BIOS or Hardware Monitor.

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

Chapter 4 BIOS Setup

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

55

85MIR2 / 85MIR2-L

4-1 About BIOS Setup

BIOS setup is an interactive BIOS program that you need to run when:

1. Changing the hardware of your system. (For example: installing a
new Hard Disk etc.)

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.

56

Chapter 4 BIOS Setup

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.

57

85MIR2 / 85MIR2-L

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).

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.
