2-1 Pentium 4 CPU and Installation

2-1.1 To Identify a Pentium 4 CPU

Intel

pentium 4

2.4 GHz / 512 / 533 / 1.5V

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)

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.

2-3 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 for this Mainboard

• This Mainboard 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.

2-4 Install VGA / AGP4X with LED1 & Jp4 Safeguard

1. To install on-board VGA, please connect your monitor directly to VGA

connector on board. Default Jp4 (2-3 closed) is designed to assure
booting system with 1.5V on-board VGA or 1.5V AGP4X add-on card.
User can choose either VGA or AGP4X as the initial display by
changing BIOS Setup (see “PNP/PCI Configurations” in BIOS Setup).

However, 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 on this mainboard.

2. To install AGP4X add-on card, please insert AGP4X card into AGP

slot on board and connect your monitor directly to the AGP4X 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 on­board VGA. On this mainboard, if user 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.

3. LED1 is a Warning LED. Whenever an AGP card is not inserted to

the AGP slot, or if the card is not a correct one, LED1 will keep
lighting up until a proper installation is done.

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 Supply 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 Supply. In this case, it is
not necessary for you to connect the on-board 4-pin Peripheral Power
Connector to your Power Supply.

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

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.

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.

• 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 clar CMOS with jumper before
resarting your 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 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 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 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

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 any 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.

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

2-8.7 Jp4: VGA/AGP4X Safeguard

1. Boot system with on-board VGA:

Default Jp4 (2-3 closed) is designed

to assure booting system with 1.5V
on-board VGA or 1.5V AGP4X add­on card. User can choose either
VGA or AGP4X as the initial
display by changing BIOS Setup
(see “PNP/PCI Configurations” in

BIOS Setup).

However, 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. Boot system with AGP4X add-on 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 on­board 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. The AGP
card should be changed until a 1.5V AGP4X card is inserted.

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 with the monitoring program.

Thermal Cable

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

• 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

58

Chapter 4 BIOS Setup

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.

59

85MIR / 85MIR-L

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 Update Utility can be loaded on a floppy diskette for upgrading saving,

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

4-5.1 Before Updating BIOS

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

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

4-5.2 Update Process

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

Users should only upgrade 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 system BIOS:

Step 1. Please visit the board maker’s website, download latest BIOS
file and AMI flash utility “AMIFLASH.EXE”. 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 “AMIFLASH.EXE” into the diskette.

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

60

Chapter 4 BIOS Setup

Step 4. Type AMIFLASH *.ROM and then press <Enter> to run BIOS
update program. (*.ROM will vary, depending on your mainboard model
and version code. Instead of typing “*”, you should type specific file
name for your specific mainboard. For example: AMIFLASH(space)
85MIR11.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. BIOS update is complete now.
