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. Thanks for the

help of saving our earth.

PART NO: 49.8B411.E01 DOC. NO: MX4GVR-EG-E0208A

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

mouse installed. JP28 controls 1st USB channel, and JP27 controls 2nd USB channel. The factory defaul

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 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…

Setting CPU Core Voltage

This motherboard supports CPU VID function. The CPU core voltage will be automaticall

detected.

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. The default setting is "table select

mode". You can adjust the FSB from "CPU Host/SDRAM/PCI Clock" for overclocking.

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.

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

can transfer files to or from laptops, notebooks, PDA devices and printers. This connecto

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, make sure to have the correct orientation when you plug in the

On the strength of RealTek RTL8100BL LAN controller on board, which is a highly-integrated

Platform LAN Connect device, it provides 10/100M bps Ethernet for office and home use, the

Ethernet RJ45 connector is located on top of USB connectors. The green LED indicates the

link mode, it lights when linking to network and blinking when transferring data. The orange

LED indicates the transfer mode, and it lights when data is transferring in 100Mbps mode. To

enable or disable this function, you may simply adjust it through BIOS.

12. COM2 Connector

This motherboard provides two serial ports. One of them is on back panel connector, and the

other is on the upper middle of board. With proper cable, you can connect it to the back panel o

chassis.

10. S/PDIF (Sony/Philips Digital Interface) 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 fo

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 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

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.

15. AOpen Bonus Pack CD 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 our official web site. Unzip the

download BIOS package (ex: WMX4GVR102.ZIP) with WinZip (http://www.winzip.com)

in Windows environment.

2. Save the unzipped files into a folder, for example, WMX4GVR102.EXE

WMX4GVR102.BIN.

3. Double click on WMX4GVR102.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.

4. You may select preferred language in the main menu, then click [Start Flash] to start the

BIOS upgrade procedure.

5. 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.

6. Press <Del> at POST to enter BIOS setup, choose "Load Setup Defaults", then “Save

Exit Setup”. Done!

It is strongly recommended NOT to turn off the power or run any application during

FLASH PROCESS.

16. Installing Onboard Sound Driver

You can use the autorun menu of Bonus CD. Choose the utility and driver and selec

model name. After selecting the model name, you can install its AGP, IAA, Audio, LAN

and USB2.0 drivers from this CD.

Del

Warning: Please avoid of using "Load

Turbo Defaults", unless you are sure

our system components (CPU, DRAM,

HDD, etc.) are good enough for turbo

settin

This motherboard comes with AC97 CODEC. This audio driver supports Windows 98SE

and upper Windows OS; you can find the audio driver from the Bonus Pack CD auto-run

menu.

Warning: The upgrade of new BIOS will permanently replace your original BIOS

content after flashing. The original BIOS setting and Win95/Win98 PnP information

will be refreshed and you probably need to re-configure your system.
