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 & 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…
3. Troubleshooting…

2. Die-Hard BIOS (User Upgrade Optional)
Recently, many viruses have been found that they may destroy bios code and data area. Therefore, this
motherboard implements a very effective hardware protection method that does not involve any software
or BIOS coding, hence it is 100% virus free. You may restore the originally mounted BIOS with 2nd BIOS
ROM by setting JP30 to pin 2-3 if it fails to act normally. This motherboard comes with one BIOS ROM, you
may contact our local distributor or reseller for purchasing the extra BIOS ROM. Please visit our website:
english.aopen.com.tw for details.

can also plug it on SYSFAN2 or SYSFAN3 connector.
4. JP21 FSB/PCI Clock Ratio
5. Setting CPU Voltage & Frequency
3. Installing CPU & Housing Fan
This jumper is used to specify the relationship of PCI and FSB clock. Generally speaking, i
f
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 adjus
t
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
A
thlon 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 frequenc
y
table in BIOS setup program. If you fix the CPU FSB frequency by JP21, the “1MHz
SteppingAdjustment” range will be changed and following JP21 setting.
Note: Some CPU fans do not have
sensor pin, so that cannot support

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

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.

This motherboard provides eight USB ports to connect USB devices, such as mouse,
keyboard, modem, printer, etc. There are two connectors on the PC99 back panel. You
can use proper cables to connect the other USB connectors to the USB modules or fron
t
panel of chassis. Please note that USB3 and USB4 support USB2.0. Compared to
traditional USB 1.0/1.1 with the speed of 12Mbps, USB 2.0 (Optional) has a fancy speed
up to 480Mbps, which is 40 times faster than the traditional one.

This motherboard comes with an ALC650 CODEC, which supports high quality of 5.1
Channel audio effects, bringing you a brand new audio experience. On the strength of the
innovative design of ALC650, you're able to use standard line-jacks for surround audio
output without connecting any external module. To apply this function, you have to install
the audio driver in the Bonus Pack CD as well as an audio application supporting 5.1
Channel. Picture bellow represents the standard location of all speakers in 5.1Channel
sound track. Please connect the plug of your front speakers to the green “Speaker out”
port, rear speakers’ plug to the blue “Line in” port and both of the center and subwoofe
r
speakers to the red “MIC in” port.
10. S/PDIF (Sony/Philips Digital Interface) Connector
S/PDIF (Sony/Philips Digital Interface) is a newest audio transfer file format, which provides
impressive audio quality through optical fiber and allows you to enjoy digital audio instead o
f
analog audio. Through a specific audio cable, you can connect the S/PDIF connector to othe
r
end of the S/PDIF audio module, which bears S/PDIF digital output. Normally there are two
S/PDIF outputs as shown, one for RCA connector, the most common one used for consume
r
audio products, and the other for optical connector with better audio quality. Same as outputs,
you can also connect RCA or optical audio products to input connectors on the module and
have the voice or music come out from your computer. However, you must have a S/PDIF
supported speaker/amplifier/decoder with S/PDIF digital input/output to connect to the S/PDIF
digital input/output to make the most out of this function.

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, UART2 Mode, make sure to have the correct orientation when you plug in the

y
our system components (CPU,
SDRAM, HDD, etc.) are good enough for

.
You can install the VIA 4 in 1 driver (IDE Bus master (For Windows NT use), VIAATAPI
Vendor Support Driver, VIAAGP, IRQ Routing Driver (For Windows 98 use), VIA Registry
(INF) Driver) from the Bonus Pack CD disc auto-run menu.
Warning: To take advantage of ATA133, it is a must to
install the latest version of VIA 4in1 driver in the Bonus CD.
For Windows2000, it cannot supports ATA133 even after
installing the latest version of VIA 4-in-1 driver until the new
release of Service-Pack 3 from Microsoft.
17. BIOS Upgrade under Windows Environment
You may accomplish BIOS upgrade procedure with EzWinFlash by the following steps,
and it’s STRONGLY RECOMMMANDED to close all the applications before you start the
upgrading.
1. Download the new version of BIOS package zip file from AOpen official web site. (ex:
http://english.aopen.com.tw/)
2. Unzip the download BIOS package (ex: WAK77333102.ZIP) with WinZip
(http://www.winzip.com) in Windows environment.
3. Save the unzipped files into a folder, for example, WAK77333102.EXE &
WAK77333102.BIN.
4. Double click on the WAK77333102.EXE, EzWinFlash will detect the model name and
BIOS version of your motherboard. If you had got the wrong BIOS, you will not be
allowed to proceed with the flash steps.
5. You may select preferred language in the main menu, then click [Start Flash] to star
t
the BIOS upgrade procedure.
6. EzWinFlash will complete all the process automatically, and a dialogue box will pop
up to ask you to restart Windows. You may click [YES] to reboot Windows.
7. Press <Del> at POST to enter BIOS setup, choose "Load Setup Defaults", then
“Save & Exit Setup”. Done!
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.

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, or on component side of PCB. For example:

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

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
