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 pin1 & pin2.

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 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.

Core Frequency = CPU FSB Clock * CPU Ratio

CPU Ratio 8x, 9x, 10x, …….22x, 23x, 24x

CPU FSB 100~180MHz

CPU CPU Core Frequency FSB Clock Ratio

Pentium 4 1.3G 1.3GHz 100MHz 13x

9. Connecting Front Panel Cable

The IrDA connector can be configured to support wireless infrared module. This

connector 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, UART2 Mode, make sure to have the correct orientation when you plug in

the IrDA connector.

If the housing has been design 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 Panel Audio Connector before you connect the cable. Do

not remove this yellow jumper cap if housing without an audio port on the front panel.

Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDD and IDE

connector. The blue connector is IDE1 for clear identification. Be careful of the pin1

orientation. Wrong orientation may cause system damage.

ttach 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.

The South Bridge in Intel 845 (Brookdale) chipset integrates a total communication solution

including 10/100Mb Fast Ethernet for Office requirement. You can install LAN Driver under

Windows95/98, WindowsNT & Windows2000 by following steps.

Manually Adding an Adapter in Windows 95 / 98

=====================================

LOCATION OF DRIVER: \Driver\Lan\E100BNT5.SYS (NDIS 5.0)

LOCATION OF SETUP FILE: \Driver\Lan\NET82557.INF

1. From the Control Panel, double-click the “Add Hardware” icon.

2. Double-click Other Devices or Network Adapters in the list area.

3. Double-click a PCI Ethernet Controller.

4. Click the Driver tab, then click Update Driver.

5. Click Next at the Update Device Driver Wizard.

6. Select "Display a list of all the drivers..." and click Next.

7. Insert the AOpen Bonus CD and click Have Disk.

8. Enter the appropriate drive for your disk media

(for example: D:\) ,and click OK.

9. Click OK at the Select Device dialog box.

10. The Update Wizard displays the message that it has found

the driver. Click Next.

11. Click Finish and restart your computer when prompted.

fter you finish the setting of jumpers and connect correct cables. Power on

and enter the BIOS Setup, press <Del> during POST (Power On Self Test).

Choose "Load Setup Defaults" for recommended optimal performance.

http://210.63.73.14/tech/download/manual/mb/k7.htm

14. Power-on and Load BIOS Setup

15. AOpen Bonus Pack CD 17. BIOS Upgrade

Open Easy Flash is a user-friendly flash method. The BIOS binary file and flash routine

are combined together and you simply run a single file to complete the flash process.

1. Download new BIOS upgrade zipped file from AOpen's web site. For example,

MX4BS102.ZIP.

2. Run shareware PKUNZIP (http://www.pkware.com) which supports

miscellaneous operation systems to extract the binary BIOS file and the flash

utility. Or Winzip (http://www.winzip.com/) in Windows environment.

3. Save the unzipped file into a bootable floppy disk.

For example, MX4BS102.BIN & MX4BS102.EXE

4. Reboot the system to DOS mode without loading any memory handler (such as

EMM386) or device driver. It needs around 520K free memory.

5. Execute A:> MX4BS102 and the program will do the rest of it.

DO NOT turn off the power during FLASH PROCESS until you are asked to!!

6. Reboot system and press <Del> to enter BIOS Setup, Choose "Load Setup

Defaults", then “Save & Exit Setup” and finish the BIOS upgrade.

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.

16. Installing Onboard Sound Driver

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

model name.

Del

Warning: Please avoid of using "Load

Turbo Defaults", unless you are sure

your system components (CPU, DRAM,

HDD, etc.) are good enough for turbo

settin

This motherboard comes with RealTek ALC201 chip, you can find the audio driver from

the Bonus Pack CD disc auto-run menu.

If you encounter any trouble to boot you system, follow the procedures

accordingly to resolve the problem.

Part Number and Serial Number

The Part Number and Serial number are printed on bar code label. You can find this

bar code label on the outside packing, on ISA/CPU slot or on component side of PCB.

For example:

Model name and BIOS version

MX4BS R1.00 July. 01. 2001 AOpen Inc.

ward Plug and Play BIOS Extension v1.0A

Model name and BIOS version can be found on upper left corner of first boot screen

(POST screen). For example:

P/N: 91.88110.201 is part number, S/N: 91949378KN73 is serial number.

MX4BS is the model name of motherboard; R1.00 is BIOS version

Make sure if the jumper settings for CPU and DRAMs are correct.

Clear CMOS.

Install the VGA card. Then connect your monitor and keyboard.

The problem was probably caused

by power supply or motherboard

failure. Please contact your reselle

or local distributor for repairing.

Perhaps your VGA card or monito

is defective.

Yes

It is very possible that your keyboard

is defective.

During system rebooting, press Del to enter BIOS Setup. Choose

“Load Setup Default".

The problem should be caused by the

IDE cables or HDD itself.

Re-install Windows 95, Windows 98 or Windows NT.

Yes

Turn off the power and unplug the AC power cable, then remove all

of the addon cards and cables, including VGA, IDE, FDD, COM1,

COM2 and Printer.

Turn on the power, and check if

the power supply and CPU fan

work properly.

Start

Check if there is display.

Press Ctrl, and Alt key at the

same time, hold them and then

press Del to see if the

stem reboots.

Turn off the system and

re-connect the IDE cable.

Check if the system can

reboot successfully.
