1. Pull CPU socket lever and up to 90-degree angle.

2. Locate Pin 1 on the socket and look for a black dot o

cut edge on the CPU upper left. Match Pin 1 and cu

edge. Then insert CPU into the socket.

3. Press down CPU socket lever to finish CPU installation.

You can clear CMOS to restore system default setting. To

clear the CMOS, follow the procedure below.

1. Turn off the system and unplug the AC power.

2. RemoveATX power cable from connector PWR2.

3. Locate JP14 and short pins 2-3 for a few seconds.

4. Return JP14 to its normal setting by shorting pin 1 & pin 2.

5. ConnectATX

ower cable back to connector PWR2.

Tip: When should I Clear CMOS?

1. Boot fail because of overclocking…

2. Forget password…

3. Installing CPU & Housing Fan

Setting CPU Core Voltage

This motherboard supports CPU VID function. The CPU core voltage will be automatically

detected and the range is from 1.1V to 1.85V. It is not necessary to set CPU Core Voltage

Setting CPU Frequency

You can set CPU frequency through the BIOS setup.

BIOS Setup > Frequency / Voltage Control > CPU Clock

Core Frequency = CPU FSB Clock * CPU Ratio

Tip: If your system hangs or fails to boot because of overclocking, simply use

<Home> key to restore the default setting.

Warning: VIA Apollo KT133A chipset supports up to maximum

133MHz(266MHz EV6 Bus), and KT133 chipset supports

100MHz(200MHz EV6 Bus) maximum. Both support 66MHz AGP

clock; higher clock setting may cause serious system damage.

Users should take their own risks for overclocking.

8. JP27 Keyboard / Mouse Wakeup

6. CNR Expansion Slots

CNR is a riser card specification to replace the AMR (Audio/Modem Riser) that supports

V.90 analog modem, multi-channel audio, and phone-line based networking. Because

CPU computing power is getting stronger, the digital processing job can be implemented

in main chipset and share CPU power. The analogy conversion (CODEC) circuit requires

a different and separate circuit design, which is put on CNR card. This motherboard

implements sound CODEC on board (can be disabled in BIOS), but reserve CNR slot fo

the option of modem function. Note that you can still use PCI modem card.

This motherboard provides keyboard / mouse wake-up function. You can use JP27 to

enable or disable function, which could resume your system from suspend mode with

keyboard or mouse installed. The factory default setting is set to “Disable” (1-2), and you

may enable this function by setting the jumper to 2-3.

9. Connect IrDA Connector

The IrDA connector can be configured to support wireless infrared module, with this

module and application software such as Laplink or Windows 95 Direct Cable

Connection, the user can transfer files to or from laptops, notebooks, PDA devices and

printers. This connector supports HPSIR (115.2Kbps, 2 meters) andASK-IR (56Kbps).

Install the infrared module onto the IrDA connector and enable the infrared function from

BIOS Setup, UART mode select, make sure to have the correct orientation when you

plug in the IrDAconnector.

7. Connecting IDE and Floppy Cables

Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDC and IDE

connector. Be careful of the pin1 orientation. Wrong orientation may cause system

damage.

10. Connecting ATX Power Connector

If the housing has been designed with an audio port on the front panel, you’ll be able to

connect onboard audio to front panel through this connector. By the way, please remove

the jumper cap from the Front Audio Connector before you connect the cable. Do no

remove this yellow jumper cap if housing without an audio port on the front panel.

The CD-IN connector is used to connect CDAudio

cable from CDROM or DVD drive to onboard sound.

The Modem-CN connector is used to connect

Mono In/ Mic Out cable from internal modem card to

onboard sound circuit.

The AUX-IN connector is used to connect MPEG

Audio cable from MPEG card to onboard sound.

fter you finish the setting of jumpers and connect correct cables. Power on

and enter the BIOS Setup, press <Del> during POST (Power On Self Test).

Choose "Load Setup Defaults" for recommended optimal performance.

14. Power-on and Load BIOS Setup

15. AOpen Bonus Pack CD 17. BIOS Upgrade

AOpen Easy Flash is a user friendly flash method. The BIOS binary file and flash routine

are combined together and you simply run a single file to complete the flash process.

1. Download new BIOS upgrade zipped file from AOpen's web site. For example,

AK73AV102.ZIP.

2. Run shareware PKUNZIP (http://www.pkware.com/) which supports

miscellaneous operation systems to extract the binary BIOS file and the flash

utility. Or Winzip (http://www.winzip.com/) in Windows environment.

3. Save the unzipped file into a bootable floppy disk.

For example, AK73AV102.BIN & AK73AV102.EXE

4. Reboot the system to DOS mode without loading any memory handler (such as

EMM386) or device driver. It needs around 520K free memory space.

5. Execute A:> AK73AV102 and the program will do the rest of it.

DO NOT turn off the power during FLASH PROCESS until you are asked to!!

6. Reboot system and press <Del> to enter BIOS Setup, Choose "Load Setup

Defaults", then “Save & Exit Setup” and finish the BIOS upgrade.

Warning: The upgrade of new BIOS will permanently replace your original BIOS

content after flashing. The original BIOS setting and Win95/Win98 PnP information

will be refreshed and you probably need to re-configure your system.

16. Installing Onboard Sound Driver

You can use the autorun menu of Bonus CD disc. Choose the utility and driver and selec

model name.

Del

Warning: Please avoid of using "Load

Turbo Defaults", unless you are sure

your system components (CPU,

SDRAM, HDD, etc.) are good enough for

turbo settin

This motherboard comes with an AC97 CODEC chip; you can find the audio driver from the Bonus

Pack CD disc auto-run menu.

If you encounter any trouble to boot you system, follow the procedures

accordingly to resolve the problem.

Part Number and Serial Number

The Part Number and Serial number are printed on bar code label. You can find this ba

code label on the outside packing, on ISA/CPU slot or on component side of PCB. Fo

example:

Model name and BIOS version

AK73(A)-V R1.00 August. 01. 2001 AOpen Inc.

Award Plug and Play BIOS Extension v1.0A

Model name and BIOS version can be found on upper left corner of first boot screen

(POST screen). For example:

AK73(A)-V is model name of motherboard; R1.00 is BIOS version

Make sure if the jumper settings for CPU and DRAMs are correct.

Clear CMOS.

Install the VGA card. Then connect your monitor and keyboard.

The problem was probably caused

by power supply or motherboard

failure. Please contact your reselle

or local distributor for repairing.

Perhaps your VGA card or monito

is defective.

Yes

It is very possible that your keyboard

is defective.

During system rebooting, press Del to enter BIOS Setup. Choose

“Load Setup Default".

The problem should be caused by the

IDE cables or HDD itself.

Re-install Windows 95, Windows 98 or Windows NT.

Yes

Turn off the power and unplug the AC power cable, then remove all

of the addon cards and cables, including VGA, IDE, FDD, COM1,

COM2 and Printer.

Turn on the power, and check if

the power supply and CPU fan

work properly.

Start

Check if there is display.

Press Ctrl, and Alt key at the

same time, hold them and then

press Del to see if the

stem reboots.

Turn off the system and

re-connect the IDE cable.

Check if the system can

reboot successfully.
