JP14 Clear CMOS

Normal Operation

(default) Clear CMOS

This motherboard has AC97 sound onboard. JP12 is used to

enable or disable onboard AD1885 CODEC chip. If you select

Disable, you can use your preferred AMR sound card.

JP12 Enable/Disable Onboard Audio

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. Tip: When should I Clear CMOS?

1. Boot fail because of overclocking…

2. Forget password…

3. Troubleshooting…

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 pins 1-2.

5. Connect ATX power cable back to connector PWR2.

Setting CPU Frequency

The CPU frequency selection is set by going into:

BIOS Setup > Chipset Features Setup > CPU Voltage Setting

CPU Ratio 1.5x, 2x, 2.5x, 3x, 3.5x, 4x, 4.5x, 5x, 5.5x, 6x, 6.5x, 7x, 7.5x, and 8x

Note: Some CPU fans do not have

sensor pin, so that cannot support

fan monitoring.

Warning: VIA694x chipset supports maximum 133MHz FSB and

66MHz AGP clock, higher clock setting may cause serious system

damage.

Home

This jumper is used to specify the relationship of PCI and

FSB clock. Generally speaking, we suggest you do not

change the default setting. But for overclocking, changing

these jumper settings becomes necessary. For example,

you must set JP29 to “5-6” and JP23 to “3-4” if you want to

overclock a 66MHz FSB clock CPU to 100MHz or higher.

Tip: If your system hangs or fails to boot

because of overclocking, simply use

<Home> key to restore the default setting

(233MHz).

Tip: The driving capability of new generation

chipset is limited due to the lack of a memory

buffer (to improve performance). This makes

DRAM chip count an important factor to take

into consideration when you install DIMMs.

Unfortunately, there is no way that the BIOS

can identify the correct chip count, you need to

calculate the chip count by yourself. The

simple rule is: By visual inspection, use only

DIMMs which are less than 18 chips.

Connecting IDE and Floppy Cable

Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDC 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. I

you enable “Suspend Mode” item in BIOS

Setup, the ACPI & Power LED will keep

flashing while the system is in suspend mode.

Connecting Front Panel Cable

Locate the power switch cable from your AT

housing. It is 2-pin female connector from the

housing front panel. Plug this connector to the

soft-power switch connector marked SPWR.

Connecting CD/Modem/ Video_Audio_IN

Configuring System Memory

This motherboard has three 168pin DIMM sockets that

allow you to install system memory up to 1.5GB. SDRAM,

VCM SDRAM, Registered SDRAM are supported.

1. First, don’t install any add-on card except AGP card.

2. Install Windows 95 OSR2 v2.1, 1212 or 1214 version and later with USB

support. Otherwise, you need to install USBSUPP.EXE.

3. Install the VIA 4 in 1 driver, which includes VIAAGP Vxd driver, IRQ routing

driver, and VIA chipset function registry program.

4. Finally, Install other add-on cards and their drivers.

Installing Windows 95

Power-on and Load BIOS Setup

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.

Del

Autorun Menu from Bonus CD Disc

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

select model name.

Warning: Please avoid of using

"Load Turbo Defaults", unless you

are sure your system components

(CPU, DRAM, HDD, etc.) are good

enough for turbo setting.

Installing Windows NT

Installing Windows 98

It is not necessary to install VIA 4 in 1 driver, just follow the installation guide of NT

and your add-on cards

1. First, don’t install any add-on card except AGP card.

2. Enable USB Controller in BIOS Setup > Integrated Peripherals > OnChip USB,

to make BIOS fully capable of controlling IRQ assignment.

3. Install Window 98 into your system.

4. Install the VIA 4 in 1 driver, which includes VIAAGP Vxd driver, IRQ routing

driver, and VIA chipset function registry program.

5. Finally, Install other add-on cards and their drivers.

You can install the VIA 4 in 1 driver (IDE Bus master, VIAAGP, IRQ Routing Driver,

VIA Registry) from the Bonus Pack CD disc autorun menu.

Installing VIA 4 in 1 Driver

Installing Onboard Sound Driver

This motherboard comes with an AD 1885AC97 CODEC and the sound controller

is in VIA South Bridge chipset. You can find the audio driver from the Bonus Pack

CD disc autorun menu.

BIOS Upgrade

Open Easy Flash is user-friendlier than traditional 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,

AX34102.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, AX34102.BIN & AX34102.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 space.

5. Execute A:> AX34102 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.

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

AX34 R1.00 Jan.04.2000 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.

AX34 is 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.

Turn on the power, and check if the power supply and

CPU fan work properly.

Start

The problem was probably caused by

power supply or motherboard failure.

Please contact your reseller or local

distributor for repairing.

Check if there is display. Perhaps your VGA card or monitor is

defective.

Yes

Press Ctrl, and Alt key at the same time, hold them and then

press Del to see if the system reboots. No It is very possible that your keyboard is

defective.

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

“Load Setup Default".

Turn off the system and re-connect the IDE cable.

Check if the system can reboot successfully. The problem should be caused by the

IDE cables or HDD itself.

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

Yes

End

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

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

and Printer..

Part No. Serial No.
