2.3 HOW TO POWER ON THE PC SYSTEM

When the mainboard has been installed successfully, there are several ways to
power on the system. Please read the following description for all the details.

¨ POWER BUTTON

The power button can be programmed by COMS setup program and it has different
features. Please refer to page 3-16 for detail function description.

¨ RTC ALARM

PC system can be started up by the RTC setting in the CMOS. You can set the
alarming date and time in the RTC memory, When RTC alarms, the PC system will
be triggered and waked up automatically on the date and time which you selected in
the BIOS setup program.

Enable the "RTC Alarm Resume” selection in the BIOS setup utility, and then you
will see the input request for the date and time. (the " RTC Alarm Resume” is
located in the "POWER MANAGEMENT SETUP”, please refer to Section 4.8),
When you have stored the RTC alarm setting, the PC system will be turned on
automatically according to the date and time which is recorded in the CMOS
memory.

¨ MODEM RING-IN

The PC system can be used as a fax machine to send or receive fax messages. But
most people still use fax machine to receive their messages because it is not
practical to have the system powered on all day long waiting for the incoming
messages. Now the problem can be solved because this mainboard can be triggered
by a modem ring-in signal.

When you have a external modem installed, you can leave the PC system power
off. Whenever there is the incoming message, the PC system will be triggered by
the ring-in signal and wake up automatically to receive the message for you. From
now on, you can tell your PC system to receive the fax message for you.

VIA KT133 ATX MAINBOARD INSTALLATION

2-5

In order to use the ring-in signal to wake up your PC system, you will have to use
the EXTERNAL MODEM and have it connected to one of the SERIAL PORTS
( COM1 or COM2 ) on the mainboard. When the mainboard detects the ring-in
signal from the serial port, the PC system will be powered on and start to receive the
incoming messages automatically..

To enable the Modem Ring-In feature, you have to run the BIOS setup utility and
enable the "Wake Up On LAN/Ring” option (it is located in the "POWER
MANAGEMENT SETUP”, please refer to Section 4.8 for the settings).

Note: This function is not available when using the internal MODEM card.

¨ WAKE ON LAN ( WOL )

There is a WOL connector CN16 on the mainboard which is designed to connect to
the signal from a LAN card which supports the Wake On LAN feature. When such
LAN card is installed, you may turn on the PC system from the remote server and
monitor the PC status. To enable this feature, you will have to use the BIOS setup
utility to enable the " Wake Up On LAN/Ring” in the BIOS setup program.

VIA KT133 ATX MAINBOARD INSTALLATION

2-6

2.4 POWER OFF THE PC SYSTEM

There are two ways to power off the system. They are “Shut Down by Power Button”
and “ Shut Down by OS”. (such as Windows® 95 and Windows® 98, you can choose
the Shut Down from the file menu and the system will be powered off immediately ).

IMPORTANT IMPORTANT IMPORTANT IMPORTANT

AMD Duron™ and Athlon™ are the very high performance processors.
However, you will easily find that the temperature measured on the
surface of the CPU is cooking hot. So the thermal management becomes
extremely important when installing AMD Duron™ and Athlon™
processors. If the CPU cooling fan is not attached to the CPU properly,
fatal damage may occur to the CPU.

According to the document from AMD, Duron™ and Athlon™ processors
require the larger heatsink. The rotation speed of the cooling fan shall be
6,600 RPM or above. The thermal grease must be applied between the
heatsink and the CPU to improve the heat dissipation. Also, please make
sure that the heatsink is fastened securely on the CPU to make sure the
perfect surface contact so that the heat can be dissipated through the
cooling fan.

Please visit the following site to have more detail of the cooling fan and
the qualified suppliers:

A jumper is a set of two, three or more jumper pins which allow users to make different
system configuration by putting the plastic connector plug (mini-jumper) on it. The
jumper setting is necessary when installing different components onto the mainboard.

(A) JP9: CMOS DATA CLEAR BUTTON

Basically, the BIOS setup program will have all the setting saved in the CMOS
memory so that the system BIOS will know how to initialize the core logic of the
mainboard. In case that you made some wrong setting in the BIOS setup program
and caused the PC system failed to boot, you can use JP9 to clear all the setting
which is saved in the CMOS memory.

Followings are the procedures to use JP9 to clear the BIOS setting which is saved in the
CMOS memory.

1. Unplug the AC power cable from the PC system.

2. Open the cabinet of the PC system.

3. Put the mini jumper on pin 2-3 of JP9 around 3 to 5 seconds and then

return it to the original position ( pin 1-2 ).

4. Close the cabinet

5. Re-connect the AC power cable.

6. Power on the PC system and then run BIOS setup program to

reconfigure the PC system.

Note: Improper BIOS setting may cause hang-up to the PC system, Should it be

happened, you may use JP9 to clear the information which is stored in
the CMOS memory and get the PC system back to normal. Improper
connection may cause permanent damage to the mainboard. Please refer
to the following steps to clear the CMOS

IMPORTANT:
After you have use JP9 and clear the setting which is saved in the CMOS
memory, we suggest that you use “Load Optimized Defaults” and have the
optimized parameters loaded into the BIOS setup program. Such
parameters were fine tuned and they will let you have the optimized
performance and stability.

VIA KT133 ATX MAINBOARD HARDWARE SETUP

(B) JP8: CPU FRONT SIDE BUS SPEED SELECTION (optional)

AMD K7 CPU uses the DDR transfer technology on its data and address busses.
Simply speaking, there are two 100MHz clock inputs connected to the K7 CPU
and the CPU will use the DDR technology to generate the 200MHz front side
system bus speed. (scalable beyond 400MHz in the feature.) Beside the 100MHz
clock frequency for the CPU which you can find from the market, this mainboard
also has the 133MHz designed onboard to support the CPU which might be using
266MHz ( or possibly 533MHz) system bus frequency in the feature. If you find
JP8 on the board, you can use JP8 to select the front side bus speed between
100MHz and 133 MHz for different CPU. Please refer to the following for the
setting of JP8:

5. How to Update the System BIOS

Before we start to discuss system BIOS update, there are some important issues
which you need to pay attention on it:

1. You can not exchange the system BIOS with another mainboard:

The system BIOS on different mainboard are different. If you take the system
BIOS from another mainboard and have it installed on this mainboard, you
may find that the mainboard fail to boot. Even the mainboard from the same
manufacturer, the content of the system BIOS can be different. So please do
not exchange the system BIOS.

2. Where to get the updated BIOS?

You can visit the web page of the supplier and down load the updated system
BIOS. Please note that you will “kill” the PC system if you have the wrong
BIOS written into the PC system. So please be sure to double check the
system BIOS before you can use it to update the system BIOS.

3. No interruption is allowed during the BIOS updating:

When the BIOS updating, please do not restart the PC system or turn the
power off. Otherwise, you will have a fragmentary system BIOS in your PC
system and it will make you unable to start the PC system. If you reset or
power off the PC system while the system BIOS is updating, you may have to
send the PC system to the suppler for troubleshooting because you do not
have the system BIOS in the PC system.

4. Do not change the onboard flash ROM:

The flash ROM is the storage device which is designed on the mainboard to
store the system BIOS. There are different kinds of the flash ROM selling in
the market. They have different capacity and different architecture. If you
install improper flash ROM onto the mainboard, it may cause unexpected
damage to the mainboard. So please never change the flash ROM on the
mainboard, otherwise, the warranty will be void.

SYSTEM BIOS UPDATE PROCEDURE

Step 1. Download the system BIOS from the web page:

1. Visit the following web page:

http://www.azza.com.tw

2. Select “TECH SUPPORT”

3. Down load “AWDFLASH.EXE” program.

4. Scroll the screen downward and find the KT133TX mainboard.

5. Select the BIOS and start to down load. (Suppose the file name is

KT133I.BIN)

Step 2. Prepare for the BIOS updating:

1. Windows is the multi task environment and some unexpected interruption

can be occurred and stop the BIOS updating. Since no interruption is
allowed during the BIOS updating. so the BIOS updating can not be made
under the Windows environment.

2. Get a floppy diskette and put it into the floppy disk drive.

3. Key-in the following command under the DOS prompt:

C:> FORMAT A:/S

4. When the diskette formatting is completed, have the files which you down

loaded from the web page copied into the floppy diskette. (KT133I.BIN and
AWDFLASH.EXE).

Step 3. Start to update the system BIOS:

1. Have the diskette which we made in Step 2 inserted in the floppy disk

drive..

2. Start the PC system and click on the “del” key to start the BIOS setup

program. Select the “Advanced BIOS features” and then make sure to select
the floppy disk drive is the first boot device.

3. Having made the boot sequence selection, save the setup and restart the PC

system.

4. When the DOS prompt “A:>” appears, run AWDFLASH.EXE program.

(You can use “AWDFLASH /?” to more detail of the program.)

5. When you have started the “AWDFLASH.EXE”, it will ask you to input the

file name of the new BIOS. Key-in “KT133I.BIN” and then click the
“ENTER” key.

6. When you see the message - Do you want to save BIOS (Y/N)?. you may

choose “Y” to have the onboard BIOS copied in to the floppy diskette. If
you do not want to make the backup copy of the onboard BIOS, simply
chose “N” and start to update the system BIO. (if you want to make a
backup copy of the onboard system BIOS, then select “Y” and then give a
file name to the backup copy.)

7. You will see from the screen whether you are going to start the BIOS

update. If you are sure that the new BIOS is correct and nothing is wrong,
chose “Y” to start the BIOS update. ( you can chose “N” and terminate the
BIOS update program.)

8. During the BIOS updating, you will see the “Programming Flash Memory”

message display on the screen. (IMPORTANT: you can not stop or reset
the PC system when the BIOS is updating.)

9. When the BIOS update is completed, remove the floppy diskette from the

floppy disk drive and restart the PC system..

10. When you see the PC system start to boot, it indicate that the BIOS update

is successful.

11. Click the “del” key during the Power On Self Test to trigger the BIOS setup

program..

12. Chose "Load Optimized Default" and have the default setting written into

the CMOS memory.

13. Chose "Save and Exit" and then restart the PC system.

14. Having finished the procedures above, the BIOS update is completed.
