This motherboard provides USB and PS2 keyboard / mouse wake-up function. You can use JP27 / JP28 to
enable or disable this function, which could resume your system from suspend mode with keyboard o
r
mouse installed. JP28 controls 1st USB channel, and JP27 controls 2nd USB channel. The factory defaul
t
setting is set to “Disable”(1-2), and you may enable this function by setting the jumper to 2-3.
You can clear CMOS to restore system default setting. To
clear the CMOS, follow the procedure below.
1. Turn off the system and unplug theAC 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…

Full-range Adjustable 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

In the past, we used to have 64-bit memory bandwidth for memory access. No matter how
many memory modules have been installed, though capacity added, the speed of access
remains the same. With 128-bit dual channel introduced, it doubles the memory bandwidth
up to 5.4GB in advanced 128-bit mode. This motherboard supports DDR400/333/266 with

9. Connecting Front Panel Cable
With IEEE1394 MAC Embedded in nVIDIA nForce2-GT chipsets (with AGERE FW802A),
the IEEE 1394 provides data transfer rate up to 400Mb/s, and USB just has 12Mbps.
Hence, the IEEE 1394 interface can connect with the devices that need high data
transferring performance, such as digital camera, scanner or others IEEE 1394 devices.
Please use the proper cable to connect with devices.
This motherboard provides six USB connectors to connect USB devices, such as mouse,
keyboard, modem, printer, etc. There are four connectors on the PC99 back panel. You
can use proper cable to connect the other USB connector to the back panel or front panel
of chassis.

this connector to the soft-power switch connector marked
SPWR.

11. Front Audio Connector
10. Connect IrDA 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
5-6 and 9-10 jumper caps from the Front Audio Connector before connecting the cable.
Please do not remove these 5-6 and 9-10 yellow jumper caps if there’s no audio port on
the front panel.

12. S/PDIF (Sony/Philips Digital Interface) Connector
(MK79G-1394 only)
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.
Pin 1
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

13. Super 5.1 Channel Audio Effects
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 outpu
t
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 subwoofer speakers to the red “MIC in”
port.

Warning: The upgrade of new BIOS will permanently replace your original BIOS
content after flashing. The original BIOS setting and Win2000/WinXP PnP
information will be refreshed and you probably need to re-configure your system.
17. BIOS Upgrade under Windows Environment
You may accomplish BIOS upgrade procedure with EzWinFlash by the following steps,
and it’s STRONGLY RECOMMENDED 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: WMK79GN102.ZIP) with WinZip
(http://www.winzip.com) in Windows environment.
3. Save the unzipped files into a folder, for example, WMK79GN102.EXE &
WMK79GN102.BIN.
4. Double click on the WMK79GN102.EXE, EzWinFlash will detect the model name
and BIOS version of your motherboard. If you had got the wrong BIOS, you will no
t
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!

If you encounter any trouble to boot you system, follow the procedures
accordingly to resolve the problem.
