The JP35 is used to enable or disable onboard PROMISE®FastTrak 100 Lite IDE RAID controller. If you
want to disable this controller, please turn off the system power first, and short pin 2 and pin 3 of JP35 by
j
umper.
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 & 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…

1. Pull up the CPU socket level and up to
90-degree angle.
2. Locate Pin 1 in the socket and look for a
(golden) cut edge on the CPU upper interface.
Match Pin 1 and cut edge. Then insert the
CPU into the socket.
3. Press down the CPU socket level and finish
CPU installation.
Plug in the CPU fan cable to the 3-pin CPU FAN connector. If you have chassis fan,
you can also plug it on FAN2 or FAN3 (without H/W monitoring) connector.

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

detected and the range is from 1.3V to 3.5V. 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 Setup
Core Frequency = CPU FSB Clock * CPU Ratio

9. Connecting Front Panel Cable
This jumper is used to specify the relationship of PCI and FSB clock. Generally speaking, if you are
not overclockers, we recommend you to set at the default setting. By the way, this motherboard
also provides “1MHz Stepping Adjustment” feature for overclockers. You can adjust CPU FSB
frequency via BIOS setup program. Based on the CPU type, the adjustment range has three level:
66~83.3 (FSB=66MHz, such as Celeron™ 533), 75~124 (FSB=100, such as Pentium®III 800E),
100~248 (FSB=133, such as Pentium®III 800EB) MHz for your choosing. If you fix the CPU FSB
frequency by JP23, the “1MHz Stepping Adjustment” range will be changed and following JP23
setting.
This motherboard has four 168-pin DIMM sockets that allow you to install PC100 or PC133
memory up to 512MB. The AX3S Plus supports non-ECC/ECC and Registered SDRAM.
Connect 34-pin floppy cable and IDE cable to floppy connector FDC and IDE / IDE RAID
connector (Applied to AX3S Plus and AX3S Plus II only). Be careful of the pin1
orientation. Wrong orientation may cause system damage.
Warning: High CPU core voltage
may be able to increase CPU
speed for overclocking, but you
may damage the CPU or reduce
the CPU lifecycle. Pin 1 ATA 33/66/100

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 user can transfer files to or from laptops, notebooks, PDA devices and
printers. 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, UART mode select, 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.
The CD-IN connector is used to connect CD Audio
cable from CDROM or DVD drive to onboard sound.
The Modem-CN connector is used to connect
Mono In/ Mic Out cable from internal modem card to
onboard sound circuit.
The Video_Audio_IN connector is used to connect

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.
14. Power-on and Load BIOS Setup
15. AOpen Bonus Pack CD 17. BIOS Upgrade
A
Open Easy Flash is more use
r
-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. Download new BIOS upgrade zipped file from AOpen's web site. For example,
AX3SP2102.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, AX3SP2102.BIN & AX3SP2102.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:> AX3SP2102 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
y
our system components (CPU, DRAM,
HDD, etc.) are good enough for turbo
settin
g
.
This motherboard comes with an AD 1885 AC97 CODEC, you can find the audio drive
r
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
AX3S Plus R1.00 Mar. 01. 2000 AOpen Inc.
A
ward 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 Plus is model name of motherboard; R1.00 is BIOS version
Make sure if the jumper settings for CPU and DRAMs are correct.

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
