1. Pull up the CPU socket lever and up to
90-degree angle.
2. Locate Pin 1 in the socket and look for a
(golden) cut edge on the CPU upper 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.

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 pin1 & pin2.
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…

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. The factory default setting is “Enable”(1-2), and you may disable this
function by setting the jumper to 2-3.

Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automaticall
y
detected and the range is from 1.10V 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.
Core Frequency = CPU FSB Clock * CPU Ratio
Warning: Intel®850E chipset
supports maximum 400MHz
(100MHz*4) system bus and
66MHz AGP clock, higher
clock setting may cause
serious system damage.

6. IrDA Connector 8. Connecting RIMM Sockets
9. Connecting Front Panel Cable
The IrDA connector can be configured to support wireless infrared module. 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, UART2 Mode, make sure to have the correct orientation when you plug in
the IrDAconnector.
If the housing is designed with an audio port on the front panel, you can connect onboard
audio to front panel through this connector. Please remove the jumper cap from the Front
Panel Audio Connector before you connect the cable. Do not remove this yellow jumper
cap if your housing does not have an audio port on the front panel.
This motherboard has four 184-pin RIMM sockets that allow you to install PC600, PC800
and PC1066 RDRAM up to 2GB. AX4T II-533 / AX4T II-533N will detect the RDRAM
speed automatically while system is in POST, but it still allows you to select the RDRAM
type manually by BIOS setup program. Please note that 400MHz FSB doesn’t support
RIMM PC1066.
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
S
PWR.

Note: Based on Intel 850E
chipset specification, AX4T II
has dual memory channel.
Please note that when you
insert RIMM modules, you
have to insert them into RIMM
1 and 4, and have terminators
inserted into RIMM 2 and 3.
Or you can insert RIMM
modules into RIMM 2 and 3,
and have terminators inserted
into RIMM 1 and 4.

This motherboard supports four USB ports. Two of them are on back panel connector, the
other two are on the left side of this motherboard. With proper cable, you can connect
them to front panel.
This motherboard has a fast Ethernet controller on chip. On the strength of LAN chip onboard, i
t
provides 10/100M bps Ethernet for office and home use, the Ethernet connector is located on top

15. AOpen Bonus Pack CD 17. BIOS Upgrade
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://www.aopen.com)
2. Unzip the download BIOS package (ex: WAX4T2533102.ZIP) with WinZip
(http://www.winzip.com) in Windows environment.

WAX4T2533102.BIN.
4. Double click on WAX4T2533102.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.
