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 factor
y
default setting is set to “Disable”(1-2), and you may enable this function by setting the jumper to 2-3.
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: 49.8A210.E01 DOC. NO: AX4B533Tube-EG-E0206A
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…

5. Setting CPU Voltage & Frequency
Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically
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.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setting
Core Frequency = CPU FSB Clock * CPU Ratio
Note: Some CPU fans do not have
sensor pin so they cannot support fan
monitoring.
CPU Fan Connector
Warning: Intel®845E chipset supports maximum 400/533MHz
(100/133MHz*4) system bus and 66MHz AGP clock; higher clock
setting may cause serious system damage.

4. 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.

9. Support Six USB2.0 Connectors
Compared to traditional USB 1.0/1.1 with the speed of 12Mbps, USB 2.0 has a fancy
speed up to 480Mbps, which is 40 times faster than the traditional one. Except for the
speed increase, USB 2.0 supports old USB 1.0/1.1 software and peripherals, offering
impressive and even better compatibility to customers. On this motherboard, all USB
connectors support USB 2.0 function. To connect those two headers, you have to use
proper USB cables and connect them to any USB models.

7. Front Audio 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.

13. 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 use
r
can transfer files to or from laptops, notebooks, PDA devices and printers. This connecto
r
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
12. Connecting CD and AUX Connector
The AUX-IN connector is used to connect MPEG
Audio cable from MPEG card to onboard sound.
The CD-IN connector is used to connect CDAudio
cable from CDROM or DVD drive to onboard sound.

11. Dr. Voice II (Volume Adjustable)
The Dr. Voice is a great feature of this 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.

10. Super 5.1 Channel Audio Effect
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 withou
t
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 bello
w
represents the standard location of all speakers in 5.1 Channel sound track. Please connec
t
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.
