2-2 Memory Installation

2-2.1 To Install DDR SDRAM Module

• This series supports up to 3GB unbuffered *DDR 400/333/266 SDRAM,

with 3 DDR DIMM slots on board. Do not insert other type of mod­ules into these slots. Memory support is upgradable to DDR 400 with­out guarantee of success in BIOS Setup.

* DDR 400 Module is supported on condition that the module is

compliant with the official DDR 400 memory module specifications.

• 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.

• 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.

2-7.1 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.

this header

A 2-pin
Jumper
Cap

The conductor inside the cap
links two header-pins together.

• A Jumper is usually but not necessarily denoted by “Jp( )” .

• In the Jumper setting diagram, all 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, mainboard could be damaged.

2-7.2 JFSB1: CPU Clock/Overclock Select

JFSB1 is designed on board as a jumper for
CPU clock select. With JFSB1, 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.

2. Select the CPU clock you want from 100/
133/166 and set JFSB1 to match your
choice. Note that the 1-2. 4-5, 7-8 setting
of JFSB1 is for auto-detection of 133/166
CPU only.

3. If you select a CPU clock which is higher
than your default CPU clock, it means that
an overclock is desired. However, if an
overclok fails to boot system, you should
resort to “Clearing CMOS” to rebooting your
system. (See Clear CMOS in next
paragraph.)

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 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 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 .

2-7.3 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.

JP1 is designed to enable the overheat safeguard for some CPUs which

JP1:

are incorporated with a protective thermal diode.

The latest AMD Athlon
XP and Duron Morgan CPUs are incorporated with such thermal diode
and can be protected by this function. Setting JP1 1-2 closed (default
setting) will get system shutdown when the above-mentioned CPUs get
to 85oC (the default protection temperature.) Only when the CPU re­turns to a cooler state can you restart your system.
For other CPUs that are not incorporated with a protective thermal diode,
please set JP1 2-3 closed to disable the function because it is a vain
design now.

Reminder: If a sudden shutdown happens to your system which has
been running well for a while with an AMD Athlon XP/Duron Morgan
CPU, this might be caused by the “Overheated CPU Shutdown” design.
Please use a better CPU cooling fan and restart your system.

Both Sensor and No-sensor Fan Connectors support CPU/AGP/Sys­tem/Case cooling fan with +12V mode. When connecting the Fan 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 connector.
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 to a Sensor Fan Connector which in turn will count the electric
pulses and send the information to the System Hardware Monitor. The
hardware Monitor Program will work out the fan rotation speed and dis­play it on screen.

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

54

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.

55

KT400A / KT400A-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.

56

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).
Example: AMIXXX.EXE(1 space)75KAV03.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.
