1. JP14 Clear CMOS
Everything you need to boot this
motherboard is included in this
Easy Installation Guide. For more
information, a complete Online
User's Manual can be found in the
Bonus Pack CD Disc. Thanks for
the help of saving our earth.
PART NO: 49.8A706.EE4 DOC. NO: AK77600GN-EG-E0312D
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 fails because of overclocking…
2. Forget password…

2. JP28 Keyboard/Mouse Wake-up Enable/Disable Jumper
This motherboard provides keyboard / mouse wake-up function. You can use JP28 to enable or disable this
function, which could resume your system from suspend mode with keyboard or mouse installed. The factory
default setting is set to “Disable” (1-2), and you may enable this function by setting the jumper to 2-3.

5. Setting CPU Voltage & Frequency
CPU Core Voltage Auto Detectable
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected and 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 Bus Frequency
Core Frequency = CPU FSB Clock * CPU Ratio
Warning: Supposed you
have had adjusted CPU
ratio on your current CPU,
and you plan to replace it
with a new CPU. Please
use <Home> key or Clear
CMOS to restore the
default setting after
reinstalling a new CPU.
Note: Some CPU fans do not have
sensor pin so they cannot support fan
monitoring.

Note:VIA®Apollo KT600 chipset supports 266/333/400MHz FSB with
performance reaches maximum 400MHz EV6 system bus and supports 66MHz
AGP clock, higher clock setting may cause serious system damage.
Tip: If your system hangs
or fails to boot because of
overclocking, simply use
<Home> key to restore the
default setting or you can
wait till the AOpen “Watch
Dog ABS” reset the system
in five seconds and system
will auto-detect hardware
again.

8. S/PDIF 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 of analog
audio. Through a specific audio cable, you can connect the S/PDIF connector to other 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 consumer 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.
This motherboard comes with an ALC650F 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 ALC650F, 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 subwoofer speakers to
the red “MIC in” port.

This jumper is used to specify the relationship of PCI and FSB clock. Generally speaking, if
you are not an over-clocker, we recommend you to set it to the default setting. Additionally,
this motherboard also provides “1MHz Stepping Adjustment” feature for overclockers to
adjust CPU FSB frequency via BIOS setup program. If you fix the CPU FSB frequency by
JP21, the “1MHz Stepping Adjustment” range will be changed according to what type of
CPU you use.

1.1 with
the speed of 12Mbps, USB 2.0 has a fancy speed up to 480Mbps, which is 40 times faster
than the traditional one.

10. Connecting Front Panel Cable
Attach the power LED, speaker, and reset switch connectors to
the corresponding pins. If you enable “Suspend Mode” item in
BIOS Setup, the ACPI & Power LED will keep flashing while the
system is in suspend mode.
Locate the power switch cable from your ATX housing. It is
2-pin female connector from the housing front panel. Plug this
connector to the soft-power switch connector marked SPWR.
11. Connecting Serial ATA Disk
12. Front Audio Connector
13. Support 10/100 Mbps LAN onboard
On the strength of Realtek 8101L LAN controller on board, this motherboard provides
10/100 Mbps Ethernet for office and home use. The Ethernet RJ45 connector is located
on top of USB connectors. The orange LED indicates the link mode, it lights when linking
to network. The green LED indicates the transfer mode and it lights when data is
transferring in 100 Mbps. To enable or disable this function, you may simply adjust it
through BIOS.
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.

To connect a Serial ATA disk, you have to have a 7-pin serial ATA cable. Connect two ends
of the serial ATA cable to the serial ATA header on the motherboard and the disk. Like
every other traditional disk, you also have to connect a power cable. Please be noted that
it is a jumper free implement; you don’t need to set jumpers to define a master or slave
disk. When connecting two serial ATA disks, the system will automatically take the one
connected to “Serial ATA 1” header as a master disk.
