This motherboard provides two kinds of audio amplify solution for you choose. If you want to use a

headphone or a speaker without amplifier and connect with “Speaker Out” jack (on the PC99 back plane),

please short the pin 2-3 and 5-6 of JP17, then pin 1-2 and 4-5 of JP18 to enable the audio amplify circuit.

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 pins 2-3 for a few seconds.

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

5. Connect ATX power cable back to connector PWR2.

Tip: When should I Clear CMOS?

1. Boot fail because of overclocking…

2. Forget password…

Full-range Auto-Detect CPU Core Voltage

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

detected and the range is from 1.1V to 1.85V.

Supported CPU Frequency

Core Frequency = CPU Bus Clock * CPU Ratio

EV6 Bus Speed = CPU Bus Clock x 2

PCI Clock = CPU Bus Clock / Clock Ratio

GP Clock = PCI Clock x 2

Tip: If your system hangs or fails to boot because of

overclocking, simply use <Home> key to restore the default

setting (433MHz) or you can wait the AOpen “Watch Dog Timer”

reset the system in five seconds and system will auto-detect

hardware again.

Warning: AMD-761

chipset supports maximum 133MHz FSB

and 66MHz AGP clock, higher clock setting may cause serious

system damage.

This motherboard comes with the AMD-761 system controller that supports 200/266MHz

EV6 bus speed. Please set the proper CPU EV6 bus frequency by JP9 and JP10.

The DDR SDRAM interface allows zero wait state bursting between the DRAM and the

data buffers at 100 or 133MHz. The two 184-pin sockets, four banks of DDR DRAM can

be composed of an arbitrary mixture of 64M/128M/256M/512M/1GB DRAMs and

maximum up to 2GB.

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.

Warning: The wrong jumper

setting may cause the CPU or

system has unexpected damage.

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) and ASK-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 IrDA connector.

This motherboard supports three USB ports and provides four USB connectors. Two o

them are on the PC99 colored back panel, and 2

port connector at left side o

motherboard. You can use proper cable to connect others USB connectors to the back

plane or front panel of chassis.

The CD-IN connector is used to connect CD Audio

cable from CDROM or DVD drive to onboard sound.

The MODEM-IN connector is used to connect Mono

IN/MIC Out cable from internal modem card to

onboard sound circuit.

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

Open Easy Flash is much more user-friendly 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,

MK7A102.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, MK7A102.BIN & MK7A102.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:> MK7A102 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

Warning: Please avoid of using "Load

Turbo Defaults", unless you are sure

our system components (CPU, DRAM,

HDD, etc.) are good enough for turbo

This motherboard comes with an AD 1885 AC97 CODEC, you can find the audio drive

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

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

For example:

Model name and BIOS version

MK7A R1.00 Jan. 11. 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: 91949378KN73is serial number.

MK7A 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.
