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.

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. RemoveATX 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. ConnectATX power cable back to connector PWR2.
Tip: When should I Clear CMOS?
1. Boot fail because of overclocking…
2. Forget password…
3. Troubleshooting…

1. Pull up the CPU socket lever and up to
90-degree angle.
2. Locate Pin 1 in the socket and look fo
r
a (golden) cut edge on the CPU uppe
r
interface. 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 System Fan (FAN2) or FAN3 (AUX Fan) connector.

5. Setting CPU Voltage & Frequency
Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automaticall
y
detected and the range is from 1.05V to 1.825V. 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 Setting
Core Frequency = CPU FSB Clock * CPU Ratio
3. Installing Processor
Note: If you do not match the CPU
socket Pin 1 and CPU cut edge well, it
may damage the CPU.

Note: Some CPU fans do not have
sensor pin so they cannot support fan

This socket supports Micro-FC-PGA2 package CPU, which is the latest CPU package
developed by Intel. Other forms of CPU package are impossible to be fitted in.

8. Connect IrDA Connector
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) andASK-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 IrDAconnector.
Connect 34-pin floppy cable and 40-pin, 80-wire IDE cable to floppy connector FDC and
IDE connector. Be careful of the pin1 orientation. Wrong orientation may cause system
damage.

IDE Connector
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.

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
the jumper cap from the Front Audio Connector before you connect the cable. Do no
t
remove this yellow jumper cap if housing without an audio port on the front panel.

Caution: By updating your motherboard, you are taking a risk
of BIOS flash failure. If your motherboard is working stable,
and there are no major bugs that had been fixed by a latter
BIOS revision, we recommend that you DO NOT try to upgrade
your BIOS.
If you intent on upgrading, PLEASE BE SURE to get the right
BIOS revision for the right motherboard model to avoid any
p
ossibility failure.
12. Die-Hard BIOS (Upgrade optional)
11. Dr. Voice
The Dr. Voice is a great feature of AX4B Pro motherboard, which can identifies what kind
of problems had occurred in the operating system. It can even clearly “tell” whether there
is a component issue or an installed issue, such as CPU, memory module, VGA, PCI
add-on card, FDD, HDD or keyboard by voice. The Dr. Voice provides four kinds of
language versions, English, German, Japanese and Chinese for your choosing. You
can select preferred language version by JP15 & JP16 jumpers. However, if you want to
disable this function, you may also set JP1 and JP2 to pin 2-3 to disable to buzzer and
speaker from making out voices respectively.

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 2
nd
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: www.aopen.com for details.

13. BIOS Upgrade under Windows environment
With outstanding R&D ability of AOpen, we now bring you a whole new BIOS Flash wizard
---- EZWinFlash. With an eye to users convenience, EZWinFlash combines the BIOS
binary code and flash module together, so the only thing you have to do is just clicking on
the utility you downloaded from web and let it helps you complete the flash process
automatically. EZWinFlash detects your motherboard and checks the BIOS version
cleverly to prevent your system from any possible failure. Moreover, EZWinFlash has been
taken into consideration to go with any windows platform you might be using, no matter i
f
you’re using Windows 95/98, 98SE/ME, NT4.0/2000, or even the latest Windows XP.
In the meanwhile, in order to provide a much more user-friendly operating environment,
AOpen EZWinFlash is natively designed to have multi-language function to provide easier
way for users’ usage in changing BIOS setting.
