This motherboard provides keyboard wake-up function. You can use the JP28 to enable or disable this

function.

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 pins 1 & pin2.

5. Connect ATX power cable back to connector PWR2.

Tip: When should I Clear CMOS?

1. Boot fail because of overclocking…

2. Forget password…

3. Troubleshooting…

Match Pin 1 and cut edge. Then insert the

CPU into the socket.

3. Press down the CPU socket lever and finish

CPU installation.

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

you can also plug it on FAN2 or FAN3 (without H/W monitoring) connector.

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

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 Speed Setup

Core Frequency = CPU FSB Clock * CPU Ratio

CPU Ratio From 5.5x to 12.5x step 0.5x

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.

7. Install DIMM Modules

6. JP21 FSB/PCI Clock Ratio

9. Connecting Front Panel Cable

This jumper is used to specify the relationship of PCI and FSB clock. Generally speaking, i

you are not overclockers, we recommend you to set at the default setting. Additionally, this

motherboard also provides “1MHz Stepping Adjustment” feature for overclockers to adjust

CPU FSB frequency via BIOS setup program. Based on the CPU type, the adjustment

range has two levels: 100~129 (FSB=100, such as Athlon 800), 130~248 (FSB=133, such

as Athlon 1000) MHz for your choosing. You may also choose a specific FSB frequency

ranging from 100~117 (say, 105, 110, 115 for example) and 120~156 with reference to a

frequency table in BIOS setup program. If you fix the CPU FSB frequency by JP21, the

“1MHz Stepping Adjustment” range will be changed and following JP21 setting.

This motherboard has installed the DDR SDRAM interface, which allows zero wait state

bursting between the SDRAM and the data buffers at 100 or 133MHz. The three 184-pin

sockets, six banks of DDR SDRAM can be composed of an arbitrary mixture o

1M/2M/4M/8M/16M/32M/64MxN DDR SDRAM with maximum up to 3GB.

Warning: High CPU core voltage

may be able to increase CPU

speed for overclocking, but you

may damage the CPU or reduce

the CPU lifecycle.

13. Power-on and Load BIOS Setup

14. AOpen Bonus Pack CD 16. BIOS Upgrade

Open Easy Flash is more use

-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,

AK77P102.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, AK77P102.BIN & AK77P102.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:> AK77P102 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.

15. Installing Onboard Sound Driver

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

model name.

Del

Warning: Please avoid of using "Load

Turbo Defaults", unless you are sure

our system components (CPU,

SDRAM, HDD, etc.) are good enough for

turbo settin

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

from the Bonus Pack CD 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

AK77 Plus R1.00 Feb. 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:

AK77 Plus 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.
