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 PCI sound card
or CNR card.

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.

Warning: INTEL i815E chipset supports maximum
133MHz FSB and 66MHz AGP clock, higher clock
setting may cause serious system damage.
Tip: If your system hangs or fails to boot
because of overclocking, simply use JP14 to
clear CMOS and restore to the default setting.
Installing CPU and Fan
Plug CPU to Socket370. Be careful of CPU
orientation. Plug in the fan cable to the 3-pin
CPUFAN or FAN 1 connector.
Note: Some CPU fans do not
have sensor pin, so that cannot
support fan monitoring.

JP23/JP29 FSB/PCI Clock Ratio
This jumper is used to specify the relationship of PCI and
host 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.

connector IDE1, IDE2. Pin1 of cable is normally marked with red color. Be careful of the
pin1 orientation. Wrong orientation may cause system damage.

Configuring System Memory
This motherboard has three 168-pin DIMM sockets that
allow you to install PC133 memory up to 512 MB. Only
SDRAM is supported.
Pin 1
Tip: The driving capability of new generation
chipset is limited due to the lack of a memor
y
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 16 chips.

JP28 Keyboard/Mouse Wakeup
This jumper is used to enable or disable Keyboard/Mouse

Peripherals > Power On Function. To implement this
function, the power supply 5V standby current must be
greater than 800mA. Note that only PS/2 mouse supports
Wake on Mouse function.

RAM Power LED & Blinking LED
The RAM Power LED indicates there is power applies to memory. It is useful to check
RAM power during Suspend to RAM. Do not unplug DIMM when this LED is On.
The Blinking LED shows you whether system is boot OK. It will continue blinking while
system is at POST procedure, and keep ON while system boot successfully.
Warning: For ATX system, there is always a standby current on the
motherboard. Please make sure that you have unplugged the ATX
power cable from the connector before you insert or pull out any CPU,
DIMM, PCI and AGP cards. Otherwise, a serious component damage
may occur.

AOpen Bonus Pack CD
You can use the autorun menu of Bonus CD disc. Choose the utility and driver and
select model name.
Installing Onboard Sound Driver
This motherboard comes with an AD 1885 AC97 CODEC. You can find the audio
driver from the Bonus Pack CD disc autorun menu.
BIOS Upgrade
AOpen Easy Flash is more user friendly 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. Get new BIOS upgrade program from AOpen's web site. For example,
AX3S102.EXE. It is recommended to save it to a bootable DOS floppy diskette for
error recovery.
2. Reboot the system to DOS mode without loading any memory handler (such as
EMM386) or device driver. It needs around 520K free memory space.
3. Execute A:> AX3S102
DO NOT turn off the power during FLASH PROCESS!
4. Reboot system and press <Del> to enter BIOS setup, Choose "Load Setup Defaults",
then “Save & Exit Setup”. Done!
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.
Power-on and Load BIOS Setup
A
fter you finish the setting of jumpers and connect correct cables. Powe
r
on and enter the BIOS Setup, press <Del> during POST (Power-On
Self Test). Choose "Load Setup Defaults" for recommended optimal
performance.
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 setting.
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
AX3S R1.00 May. 04. 2000 AOpen Inc.
Award Plug and Play BIOS Extension v1.0A
Copyright © 1998, Award Software, Inc.
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.
AX3S 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.
The problem was probably caused
by power supply or motherboard
failure. Please contact your reselle
r
or local distributor for repairing.
Perhaps your VGA card or monito
r
is defective.

The problem should be caused by the
IDE cables or HDD itself.

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
s
