Intel

pentium 4

2.4 GHz / 512 / 533 / 1.5V

(Including hyper-threading CPU)

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 hyper-threading 3.06GHz 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.

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

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/Remove DDR DRAM Module

• This series 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.

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

connector on board. Default Jp11 2-3 closed is to assure booting
system with on-board VGA or 1.5V AGP4X 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 setting.

2. To install AGP4X card on this mainboard, please insert AGP4X card

into AGP slot and connect your monitor directly to the AGP4X card.

To assure the use of a correct AGP4X card of 1.5V, please set Jp11

to 1-2 closed to allow only 1.5V AGP 4X card to boot system. With
Jp11 1-2 closed, safeguard is enabled against AGP2X card. That is,
system cannot boot with 3.3V AGP2X card or on-board VGA. In this
setting, 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 AGP4X card
before booting this system.

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 model.

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

3. If you use an ATX power Supply of an older version than V2.03, there
will be no square-shaped +12V Connector. So please connect the
onboard 4-pin Peripheral Power Connector to the 4-pin Peripheral
Power Connector of your Power Supply.

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

Pin 2-3 closed

Jumper with

all pins open

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 Jp4: CPU Clock Select

Jp4 is designed to select 100/133MHz CPU
clock for the system. Setting Jp4 to 1-2 closed
will allow CPU on board to autodetect its own
frequency and apply it to the System Bus.
Setting JP4 to 2-3 closed will manually config­ure a 100MHz CPU to 133MHz.
However, overclocking should always take the
whole mainboard into account. There is no 100%
guaranty of success. In case overclocking fails,
system boot will fail. You should then take the
autodetect setting to boot system. Even more,
you should clear CMOS before rebooting
system. ( See JBAT 1 Clear CMOS ).

85MR3 / 85MR3-L

Further 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 .

2-8.2 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, restore the JBAT1 setting to Pin1-2 closed.

4. CMOS data are restored to default now. Remember never clear

CMOS when system power is on.

2-8.3 JP1: KB /Mouse / Power Button Select

JP1 is designed to select keyboard/Mouse/Power button as the power­on controller. Setting JP1 to 1-2 closed will allow users to power on
system by power button while setting JP1 to 2-3 closed will allow users
to power up system by keyboard/Mouse. Yet users still have to choose
the K/B Power-on mode on BIOS. (See Integrated Peripherals” in BIOS

2-8.4 Jp10: LAN Controller Select (85MR3-L only)

JP10 is a 2-pin jumper for enabling or disabling the on-board LAN
Controller. Users can set JP10 OPEN to enable the on-board LAN Con­troller so as to set up the LAN driver, or to set it CLOSED to disable the
on-board LAN Controller. In such case, users are free to use an add­on PCI LAN card for networking.

2-8.5 Jp11: VGA/AGP 4X Safeguard

1. Default Jp11(2-3 closed) is to disable safeguard against 3.3V AGP2X
card and allow booting system with either 1.5V on-board VGA or 1.
5V AGP4X add-on card. User can choose either VGA or AGP 4X as
the initial display by changing BIOS Setup(see“PNP/PCI
Configurations ” in BIOS Setup).

2. Jp11 at 1-2 closed is to enable safeguard against AGP2X card and
allow only 1.5V AGP 4X card to boot system. With JP11 1-2 closed,
system cannot boot with onboard VGA or AGP 2X card. 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
to a 1.5V AGP 4X card for booting system.

Warning:

• If a 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.

Both Sensor and No-sensor Fan Connectors support CPU/AGP/Sys­tem/Case cooling fan with +12V mode. When connecting the wire to
any Fan Connector, 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.

A Hardware Monitor chipset is on board, with which users can install
a Hardware Monitor Utility and read the fan speed transmitted from the
sensor fan. Otherwise, users 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.

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

available to cards installed in the ISA expansion bus first, then any remain­ing 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 In­terrupt number and address. Double-Clicking Computers to see all the in­terrupts 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

60

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.

61

85MR3 / 85MR3-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 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.

62

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).

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.
