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 SDRAM Module

• This mainboard supports up to 2GB unbuffered *DDR 400/333/266

SDRAM, with 2 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 DDR 400 Memory Module Validation
Program for Chipset VIA KT333(CF)/P4X400A. 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.

2-3 AGP Slot Installation

The AGP slot on board supports 1.5V AGP 4X card only. A Rib is spe­cifically added to the 4X slot so as to match the AGP 4X card. To 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 support a data transfer rate up to 1GB/sec.

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.

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 with jumper cap.

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 CPU Clock/Overclock Select

SW1 is designed on board as a 5-dip switch for CPU clock select.

1. Before setting the CPU clock, please read the Identification Legend
on the CPU, and find the Max FSB and divide it by two. The result is
the default CPU clock.

2. Select the CPU clock you want from 100/133/166MHz and set SW1
to match your choice.

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 restore the default setting and then
clear CMOS to rebooting 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 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 .

2-7.3 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.

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 to 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.

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

QT

SL-KT400-A4C

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.

48

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.

49

SL-KT400-A4C

Step 4. Type AMIFLASH *.ROM and then press <Enter> to run BIOS
update program. (*.ROM will vary, depending on your mainboard model
and version code. Instead of typing “*”, you should type specific file
name for your specific mainboard. For example: AMIFLASH(space)
75FRV11.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.
