Chapter 2 Hardware Setup

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:

2-1 Pentium 4 CPU Installation
2-2 Pentium 4 CPU Fan Installation
2-3 Memory Installation
2-4 AGP slot Installation
2-5 HDD/FDD Installation
2-6 ATX 2.03 Power Supply Installation

2.4 GHz / 512 / 533 / 1.5V

( HT CPU 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.

How to tackle with the memory Modules:

• Make sure to unplug your Power Supplier 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 in a
socket improperly will damage the memory module and slot.

• 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 SDRAM, with 2
DDR DIMM slots on board.

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.

2-7.1 JFSB1: CPU Frequency Select

JFSB1 is designed on board for CPU frequency select.

1. Setting JFSB1 1-2 closed will allow CPU on board to Auto Detect its
own frequency and apply it to the System Bus.

2. Setting JFSB1 2-3 closed is for 100
MHz CPU.

3. Setting JFSB1 all pins open is for
133 MHz CPU. 100MHz CPU will
fail to boot herewith.

4. 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 .

2-7.2 JBAT1: Clear CMOS

When you have problems 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.

should still enter BIOS setup to
choose the Wake Up/ Power On
mode.
USB keyboard/mouse Wake Up func­tion is not supported in this series.

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.

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

51

85ERV2-C / 85ERV2-CL

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.

52

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 the zip files
of the latest BIOS and AMI flash utility “AMIFLASH.EXE” for your
mainboard. After unzipping, 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.

53

85ERV2-C / 85ERV2-CL

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)LDL005.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.
