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.

2-1.2 CPU Installation with Socket 462

This series is built with CPU Socket 462 supporting the AMD CPUs
Athlon, Athlon XP and Duron:

• Follow the steps described in this section to install CPU into the on­board Socket 462.

• After installation of CPU, you must also install a proper cooling fan
on top of the CPU and connect the Fan cable to the CPU fan
connector.

1. First pull sideways the lever of
Socket 462, and then turn it up

0

so as to raise the upper layer

90
of the socket from the lower
platform.

2. Configure Pin 1 of CPU to Pin 1

SOCKET 462

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 pin holes of the
socket.

2-2 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.

2-2.1 To Install DDR DRAM 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 has passed

Soltek DDR 400 Memory Module Validation Test. Soltek Computer
Inc. typically runs a Memory Module Validation Program for DDR
400 Modules. Detailed information is available in Soltek Web Site:
WWW.soltek.com.tw

• 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.

2-2.3 Warning Indicator LED1: DIMM Slots Powered On

An indicator LED1 is designed on board. Whenever system is started
or is in STR status (Suspend to RAM), all the DIMM slots on board will
also get powered on with the set voltage, resulting in LED1 lighting up.
This indicator LED1 is to warn users that, whenever DIMM slot is pow­ered on, no memory module should be removed from or added into it.

2-3 AGP Slot Installation

The AGP slot on board supports 1.5V AGP 4X card only. If an AGP8X
card is inserted, it will only perform its job like an AGP4X card. A Rib is
specifically added to the 4X slot so as to match the AGP 4X card.
insert a 3.3V AGP 2X card into the AGP 4X slot will damage the system
chip and burn the 1.5V circuitry.
An AGP 4X card will provide 1GB/sec transfer rate.

How to tackle the Jumpers:

A 3-pin Jumper

1 23

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 to link
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 with jumper cap.

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 setting.
Otherwise, mainboard could be damaged.

2-8.1 FREQ2 & FREQ1: CPU Clock/Overclock Select

FREQ2 and FREQ1 are designed on board as jumpers for CPU clock
select. With FREQ2 & FREQ1, 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. If FREQ2 & FREQ1 are set to 100MHz setting, it indicates that
overclock is not desired. The CPU will boot system with 100MHz
even if a 133MHz CPU is used.

3. If FREQ2 & FREQ1 are set to 133 / 166MHz setting, the CPU will try
to boot system with 133/166MHz even if a 100MHz CPU is used.
However, if overclok fails, you have to restore jumper setting to
100MHz default setting and clear CMOS to reboot system.

KT400-A4 / KT400-A4L

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 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 .

2-8.2 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 1-2 closed.

3. After 2 or 3 seconds, return the JBAT1 setting to Pin2-3 closed.

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

2-8.3 JP1: Overheated CPU Shutdown (ABSII)

JP1 is the Anti-Burn Shield (ABSII) Selector
JP1 is designed to enable the overheat safeguard for some CPUs which

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 shut down the system when the above-mentioned CPUs
get to 85
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 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.

• 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

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

KT400-A4 / KT400-A4L

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).

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.

if you press <Enter> before you enter any new password into the

NOTE: If you forget or lose a supervisor password, the only
way to access the system is to clear the CMOS. All setup
