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.

The following topics are included in this chapter:

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 is 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

(multiplier 18 x 133MHz CPU clock);

2A GHz depicts that this CPU is an A version, locked to 2.0 GHz

working frequency (multiplier 20 x 100MHz CPU clock);

2) CPU L2 Cache: This part depicts the L2 Cache size. For Example:
512 stands for 512 MB L2 Cache; 256 stands for 256 MB L2 Cache;

3) System Clock: This part depicts the System Clock (Front Side Bus)

to be provided by the CPU. For example:

533 stands for a 533MHz system bus provided by this 133MHz CPU

times 4;
400 stands for a 400 system clock provided by a 100 MHz CPU x 4;
(Note: P4 CPU is a quadpumped CPU. The system bus is provided by
the CPU clock x 4. Therefore, user can figure out the P4 CPU clock
from the System Clock devided by 4.)

4) CPU Voltage Vcore: This part depicts the CPU Voltage. For example:

1.5V stands for a CPU of 1.5Vcore.

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 with Warning LED

How to tackle the memory Modules:

• Make sure to unplug your power supply before adding or removing
memory module.

• Pay attention to the orientation of the DIMM slots.

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

2-3.1 To Install DDR DRAM Module

• This series supports up to 3GB unbuffered DDR 333/266/200 DRAM,
with 3 DDR DIMM slots on board. Do not insert other type of modules
into these slots. DDR 400 Memory Module can be compatible with
this series if it has passed Soltek validation. soltek Computer Inc.
typically runs a DDR 400 Memory Module Validation Program for
Chipset VIA P4X400A. Detailed information is available in Soltek Web
Site: WWW.soltek.com.

• 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 2GMHz or higher CPU.

To set up Power Supply on this series:

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.

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, all jumper pins covered with
black marks stand for closed pins by jumper caps.

1 13313

Jp X

Jumper with

Pin 2-3 closed

Jumper with

all pins open

Jumper with

Pin 1-2 closed

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

2-8.1 Jp1: CPU Clock/Overclock Select

Jp1 designed on board for CPU clock select and 100MHz CPU
overclocking. With Jp1, user can choose the way for a 100MHz CPU to
run an overclock on board.

1. If Jp1 is set to 1-2 closed, the auto-detect
mode will recognize the CPU clock
automatically and send the signal to system
chips. No overclocking will be implimented
in this case. That is, a 100MHz CPU will boot
system with 100MHz CPU clock and provide
4X100 MHz system bus. A 133MHz CPU will
boot system with 133MHz and provide a
4X133 MHz system bus.

2. If Jp1 is set to 2-3 closed, CPU is set at
100MHz, indicating that 133MHz overclock
is not desired. The CPU will boot system with
100MHz even if a 133MHz CPU is used.

3. If Jp1 is set to 1-2-3 all open, CPU is set at
133MHz, indicating that 133MHz overclock
is desired. The CPU will try to boot system
with 133MHz even if a 100MHz CPU is used.

Chapter 2 Hardware Setup

Note 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 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 of 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, return the JBAT1 setting to Pin1-2 closed.

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

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, 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.

• 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 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

85ERV2 / 85ERV2-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

85ERV2 / 85ERV2-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). For
example, you may type “amiflash(space)85ERV211.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.
