Tip: When should I Clear CMOS?

1. Boot fail because of overclocking…

2. Forget password…

3. Troubleshooting…

Normal Operation

(Default) Clear CMOS

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. Remove ATX power cable from connector PWR2.

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

. Return JP14 to its normal setting by shorting pin 1 & pin2.

5. Connect ATX power cable back to connector PWR2.

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

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

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

cut edge. Then insert CPU into the socket.

3. Press down CPU socket lever to finish CPU

installation.

Note: If you do not match the CPU

socket Pin 1 and CPU cut edge well,

This jumper is used to specify the relationship of PCI and FSB clock. Generall

speaking, if you are not an overclocker, we recommend you to set at the default setting.

Plug in the CPU fan cable to the 3-pin CPUFAN connector. If you have housing fan,

you can also plug it on FAN2 connector.

Tip: If your system hangs or fails to boot

because of overclocking, simply use <Home>

key to restore the default setting.

CPU Core Voltage Auto-Detection

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

detected from 1.1V~1.85V. It is not necessary to set CPU Core Voltage.

Setting CPU Frequency

This motherboard is CPU jumper-less design, you can set CPU frequency through the

BIOS setup, and no jumpers or switches are needed.

BIOS Setup > Frequency/Voltage Control > CPU Host Clock (CPU/PCI)

Core Frequency = CPU FSB Clock * CPU Ratio

CNR (Communication and Network Riser) is a riser card specification to replace the

MR (Audio / Modem Riser) that supports V.90 analog modem, multi-channel audio, and

phone-line based networking. This motherboard implements sound CODEC on board

(can be disabled in BIOS), but reserves CNR slot for the option of modem function. Note

that you can still use PCI modem card. And due to hardware limitation, if the

motherboard you purchased implements an optional Creative CT5880 Audio Controller,

then there will not be CNR expansion slot on your motherboard. Pin 1

[CD-ROM]:Driver\LAN\RTL8100\Windows\Windows ME (for Windows ME)

3. Follow the procedure and insert your system disk (Win98/Win98 SE/Windows2000/Windows

ME) to complete setup step.

4. Win98/Win98 SE/Windows2000/Windows ME will finish the other installation procedures

automatically, and then restart your system.

12. Power-on and Load BIOS Setup

13. Installing LAN Driver (MK73LE-N Only)

10. Installing Front Audio

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.

11. Connecting CD / MODEM / AUX-IN

Warning: Please avoid using

"Load Turbo Defaults", unless you

are sure your system components

(CPU, DRAM, HDD etc.) are good

enough for turbo setting.

The CD-IN connector is used to connect CD Audio

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

udio cable from MPEG card to onboard sound.

15. Installing Onboard AGP Driver 17. BIOS Upgrade

Open Easy Flash is user-friendlier than traditional 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,

MK73LEN102.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, MK73LEN102.BIN & MK73LEN102.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:> MK73LEN102 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

16. Installing Onboard Audio Driver

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

select model name. This motherboard comes with an AC97 CODEC. You can find the audio driver from

the Bonus Pack CD disc autorun menu.

VIA Apollo KLE133 chipsets integrates a 2D/3D graphics accelerator and provides

GP 2X/4X incredible performance to access main memory at over 1GB/s. You can

find the AGP driver from the autorun menu of Bonus Pack CD.

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

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

For example:

Model name and BIOS version

MK73LE-N R1.00 Oct. 01. 2001 AOpen Inc.

ward 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:

P/N: 91.88110.201 is part number, S/N: 91949378KN73 is serial number.

MK73LE-N 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.
