Chapter 1
Overview
AX3L is a new generation Socket 370 based system board that utilizes Intel
82440LX AGPset on ATX PCI/ISA platform. This AGPset is designed for
Pentium II CPU, and supports new architectures such as high speed AGP
graphic port, SDRAM, Ultra DMA/33, Bus master IDE and USB port. It has
three Dual in-line Memory Module (DIMM) that allow to install SDRAM
memory and expand up to a maximum of 768MB. Since the cache is on the
Pentium II CPU card (connector SLOT1), there is no second level cache
onboard Also, AX3L uses 2M bit Flash ROM BIOS to reserve for future new
functions.
Not only above features, AX3L also implements many special features as
following.
Jumper-less Design Celeron PPGA VID signal and SMbus clock generator
provide CPU voltage auto-detection and allows user to set CPU frequency
through CMOS setup, no jumper or switch is needed. The correct CPU
information is saved into EEPROM, with these technologies, the
disadvantages of Pentium base jumper-less design are eliminated. There will
be no worry of wrong CPU voltage detection and no need to re-open the
housing if CMOS battery loss. The only jumper left is to clear CMOS, which is
a safety hook if you forget the password.
Battery-less AX3L implements EEPROM and special circuit (patent applied)
that allows you to save your current CPU and CMOS Setup configurations
without the need of battery. The RTC (real time clock) can also keep running
as long as power cord is plugged. If you lose your CMOS data by accident, you
can just reload the CMOS configurations from EEPROM and the system will
recover as usual.
APM Suspend To Hard Drive "Immediately" turns on system and goes back
to the original screen before power down. You can resume your original work
directly from hard disk without go through the Win95 booting process and run
your application again. Suspend to Hard Drive saves your current work
(system status, memory image) into hard disk. Note that you have to use

Overview
VESA compatible PCI VGA, Sound Blaster compatible sound card with APM
driver, for Suspend to Hard Drive to work properly.
Zero Voltage Wake on Modem In conjunction with ATX soft power On/Off, it
is possible to have system totally power off and wakeup to automatically
answer a phone call such as answering machine or to send/receive fax. The
most important break through is not only external box modem but also internal
modem card can be used to support Wake On Modem. The AX3L and MP56
internal modem card implement special circuit (patent applied) to make sure
the modem card work properly without any power.
Wake on LAN This feature is very similar as Wake On Modem, but it is
through local area network. To use Wake on LAN function, you must have a
network card that supports this feature and also need to install a network
management software.
Wake on RTC Timer The Wake Up Timer is more like an alarm, which
wakes up and power on your system at a pre-defined time for specific
application. It can be set to wake up everyday or on specific date within a
month. The date/time accuracy is second.
Wake on Keyboard This feature allows you power on your system by clicking
the hot key that you specified. Besides, you also may disable the function of
power button and let the system can only be powered on through the preset
keys (like a password).
Wake on Mouse This function allows you wake up the system by clicking
mouse button twice successively.
AC Power Auto Recovery A traditional ATX system should remain at power
off stage when AC power resumes from power failure. This design is
inconvenient for a network server or workstation, without an UPS, that needs
to keep power-on. This motherboard implements an AC Power Auto Recovery
function to solve this problem. In BIOS Setup setting the item to Enabled lets
the system can automatically power-on after AC power resumes.
High Efficient Synchronous Switching Regulator Most of the current
switching designs are Asynchronous mode, which from the technical point of
view, still consumes very high power as well as heat. AX3L implements high
efficient synchronous switching design that the temperature of MOS FET is far
less than Schottky diode of asynchronous design.
Over Current Protection The Over Current Protection was very popular
implemented on the Baby AT or ATX 3.3V/5V/12V switching power supply.
However, the new generation Celeron PPGA CPU uses different voltage that
have regulator to transfer 5V to CPU voltage (for example, 2.0V), and make 5V
over current protection useless. AX3L with switching regulator onboard support
CPU over current protection, in conjunction with 3.3V/5V/12V power supply
provide the full line over current protection.

Overview
CPU and Housing Fan Monitoring AX3L has one more "fan monitoring"
function to prevent system overheat. There are two fan connectors, one is for
CPU and the other can be an extra housing fan. The system will report and
alarm fan malfunction though utility software such as Hardware Monitor utility
(Small Icon for Hardware Monitoring).
CPU Thermal Protection AX3L has a special thermal detection circuit to have
warning through application software when the temperature is higher than a
predefined value.
System Voltage Monitoring Further more, AX3L implements a voltage
monitoring system, As you turn on your system, this smart design will continue
to monitor your system working voltage. If any of the system voltage is over
the component's standard. There will be alarm though utility software such as
Hardware Monitor utility (Small Icon for Hardware Monitoring) for a warning to
user.
Full-range CPU core voltage This motherboard supports the CPU core
voltage from 1.3V to 2.05V, that can be applied to various CPU type in future.
Resetable Fuse This motherboard implements resetable fuses to prevent any
accidental short circuit caused by keyboard or USB devices hot plug.
FCC DoC certificate AX3L has passed FCC DoC test. The radiation is very
low, you can use any kind of housing.
Powerful Utility Software AOpen Bonus Pack CD disc contains many useful
utilities, such as Norton Antivirus, AOchip, Hardware Monitoring Utility, and
Suspend to Hard Drive utility.
Note: This motherboard is battery-less, that means the RTC
(real time clock) can keep running without battery as long as
the power cord is plugged. But in case of power failure or the
power cord unplugged, you need to reset date and time from
"Standard CMOS Setup" section of BIOS Setup. For more
information, please see "Chapter 3 BIOS Setup".

1.2 APM Suspend to Hard Drive
Suspend to Hard Drive saves your current work (system status, memory and
screen image) into hard disk, and then the system can be totally power off.
Next time, when power is on, you can resume your original work directly from
hard disk within few seconds without go through the Win95 booting process
and run your application again. If your memory is 16MB, normally, you need to
reserve at least 16MB HDD space to save your memory image. Note that you
have to use VESA compatible PCI VGA (AOpen PV70/PT70), Sound Blaster
compatible sound card and sound driver that supports APM (AOpen
AW32/AW35) for Suspend to Hard Drive to work properly. Of course, we
recommend choosing AOpen products for best compatibility.
To use Suspend to Hard Drive:
1-4
Overview
1. Go into BIOS setup, Power Management Æ Suspend Mode Option, select
"Suspend to Disk".
2. Go into BIOS setup, PNP/PCI Configuration Æ PnP OS Installed, select
"No". This can give BIOS the capability to allocate system resources for
Suspend to Hard Drive.
3. Boot up your system into DOS command prompt. If you are Win'95 user,
Please restart your Windows 95 under "Command Prompt" by pressing
"F8" while system shows "Windows 95 Starting ...". Choose "Safe Mode
Command Prompt Only" from selection so that system will start in DOS
command prompt.
4. Copy AOZVHDD.EXE to the root directory of your C: drive.
5. Option 1: Use /file switch (applied to FAT16 file system):
Please use following command to create a hidden file in the root directory
of your hard disk for Suspend to Hard Drive to save the system status and
memory image.
C:>AOZVHDD /c /file
Please make sure that you have enough continuous HDD space for
creating this hidden file. For example, if you have 32MB of system memory
and 4MB of VGA memory, you need at least 36MB (32MB + 4MB) of
continuous HDD space. If AOZVHDD failed to allocate the HDD space, you
may run "DEFRAG" Utility or "Disk Defragmenter" which come with MSDOS or Win'95 to free HDD space.
1-5
Overview
Option2: Use /partition switch (applied to FAT16/FAT32 file system):
To create a separate partition for Suspend to Hard Drive, please make sure
you have reserved a free partition. We suggest you reserve the free
partition which space is appropriate for your future memory expansion. For
example, if you have 32MB of system memory and 4MB of VGA memory
currently, but you plan to upgrade system memory to 64MB in the near
future, then you may reserve a 68MB (64MB+4MB) space by using a disk
utility (such as fdisk). Next, use following command to create a suspend
partition:
C:>AOZVHDD /c /partition
If there is no extra free partition and you don't want your data lost, please
do not use this partition method.
6. After creating above partition or hidden file, please reboot your system.
7. Push suspend switch (momentary mode) or use Win95 Suspend icon to
force system goes into Suspend to Hard Drive mode and then turn system
power off by power switch of your power supply.
8. Next time when you turn on your system, it will resume to your original work
automatically.
Warning: Note that Intel Bus Master and Ultra DMA/33
IDE driver are not fully compatible with Suspend to Hard
Drive function, installing these drivers may cause the
system unstable. Under this situation, please uninstall the
drivers.

1.3 Zero Voltage Wake on Modem
The Wake on Modem discussed here is to wakeup from true power off
(identified by fan of power supply is off), This motherboard still supports
traditional green PC suspend mode but it is not discussed here.
With the help ATX soft power On/Off, it is possible to have system totally
power off (The traditional suspend mode of power management function does
not really turn off the system power supply), and wakeup to automatically
answer a phone call such as answering machine or to send/receive fax. You
may identify the true power off by checking fan of your power supply. Both
external box modem and internal modem card can be used to support Wake
on Modem, but if you use external modem, you have to keep the box modem
always power-on. AOpen AX3L and internal modem card implement special
circuit (patent applied) and make sure the modem card works properly without
any power. We recommend choosing AOpen modem card (MP56) for Wake
on Modem applications.

COM1 or COM2. Internal modem card wake up signal is
detected through cable from connector RING (on modem card)
to WOM (on mainboard).
Note: If you use external modem, the power of external modem
must be kept on to receive signal from telephone line. Internal
modem card has no such limitation.
1.4 System Voltage Monitoring
This motherboard implements a voltage monitoring system. As you turn on
your system, this smart design will continue to monitor your system working
voltage. If any of the system voltage is over the component's standard. There

Overview
1.7 Battery-less Design
To preserve the earth, AOpen AX3L implements the battery-less motherboard
design. There is no need to have battery for RTC (real time clock) and CMOS
Setup as long as ATX power cable is plugged. In case of the AC power is
shutdown or power cord is removed by accident, the CMOS Setup and system
configuration can be restored from EEPROM, only the system clock needed to
be re-set to current date/time.
For the convenience of end user, AX3L still shipped with one Lithium (CR-
2032) battery. If you prefer to use battery, you can still insert it into battery
socket. The RTC will still keep running even power cord is removed.

Hardware Installation
2.2.1 Selecting the CPU Frequency
Celeron PPGA VID signal and SMbus clock generator provide CPU voltage
auto-detection and allow user to set CPU frequency through CMOS setup, no
jumper or switch is needed. The correct CPU information is saved into
EEPROM, with these technologies, the disadvantages of Pentium base
jumper-less design are eliminated. There will be no worry of wrong CPU
voltage detection and no need to re-open the housing if CMOS battery loss.
The CPU frequency selection is set by going into:
BOIS Setup Æ Chipset Features Setup Æ CPU Clock Frequency
(The possible setting is 66.8, 68.5, 70, 73.8, 75, 78.5, 83.3 MHz)
BOIS Setup Æ Chipset Features Setup Æ CPU Clock Ratio
(The possible setting is 1.5x, 2x, 2.5x, 3x, 3.5x, 4x, 4.5x, 5x, 5.5x, 6x, 6.5x, 7x, 7.5x,
and 8x)
Core frequency = Ratio * External bus clock
INTEL Celeron PPGA CPU Core Frequency Ratio External Bus Clock
Celeron PPGA 300A 300MHz= 4.5x 66MHz
Celeron PPGA 333 333MHz= 5x 66MHz
Celeron PPGA 366 366MHz= 5.5x 66MHz
Celeron PPGA 400 400MHz= 6x 66MHz
Celeron PPGA 433 433MHz= 6.5x 66MHz

Hardware Installation
2.4 Configuring the System Memory
The DIMM types supported are EDO
(Extended Data Out) and SDRAM
(Synchronous DRAM). This mainboard has
three 168-pin DIMM sockets (Dual-in-line
Memory Module) that allow you to install
system memory up to 768MB EDO DRAM
or 384MB SDRAM.
Pin1
DIMM modules can be identified by the following factors:
I. Size: single side, 1Mx64 (8MB), 2Mx64 (16MB), 4Mx64 (32MB), 8Mx64
(64MB), 16Mx64 (128MB), and double side, 1Mx64x2 (16MB), 2Mx64x2
(32MB), 4Mx64x2 (64MB), 8Mx64x2 (128MB).
Tip: Here is a trick to check if your DIMM is singleside or double-side -- if there are traces connected to
golden finger pin 114 and pin 129 of the DIMM, the
DIMM is probably double-side; otherwise, it is singleside. The following figure is for your reference.
168
Pin 129
II. Speed:
SDRAM: normally marked as -12, which means the clock cycle time is 12ns
and maximum clock of this SDRAM is 83MHz. Sometimes you can also
find the SDRAM marked as -67, which means maximum clock is 67MHz.
EDO: the access time of EDO RAM can be 50ns or 60ns.
Pin 114

Hardware Installation
III. Buffered and non-buffered: This motherboard supports non-buffered
DIMMs. You can identify non-buffered DIMMs and buffered DIMMs
according to the position of the notch, following figure is for your reference:
buffered
non-buffere d
Reserved
Because the positions are different, only non-buffered DIMMs can be
inserted into the DIMM sockets on this motherboard. Although most of
DIMMs on current market are non-buffered, we still suggest you to ask your
dealer for the correct type.
IV. 2-clock and 4-clock signals: Although both of 2-clock and 4-clock signals
are supported by this motherboard, we strongly recommend choosing 4clock SDRAM in consideration of reliability.
Tip: To identify 2-clock and 4-clock SDRAM, you
may check if there are traces connected to golden
finger pin 79 and pin 163 of the SDRAM. If there are
traces, the SDRAM is probably 4-clock; Otherwise, it
is 2-clock.
V. Parity: This motherboard supports standard 64 bit wide (without parity) and
72-bit wide (with parity) DIMM modules.
There is no jumper setting required for the memory size or type. It is
automatically detected by the system BIOS, and the total memory size is to
add them together. The maximum is 768MB.
LX chipset can only use 3V EDO or SDRAM, so we can mix EDO and SDRAM.
Every DIMM socket can be EDO or SDRAM. For EDO, maximum is 256MB.
For SDRAM, maximum is 128MB.
Total Memory Size = Size of DIMM1 + Size of DIMM2 + Size of DIMM3
Note: 768MB memory is achieved by using double-sided
buffered EDO DIMMs.

Tip: The parity mode uses 1 parity bit for each byte, normally it is
even parity mode, that is, each time the memory data is updated,
parity bit will be adjusted to have even count "1" for each byte.
When next time, if memory is read with odd number of "1", the
parity error is occurred and this is called single bit error detection.

Clock Throttling means at the Doze/Standby state,
the CPU clock count in a given time (not the
frequency) is reduced to the ratio specified in this
parameter. Actually, the period per CPU clock is not
changed. For example, a 66MHz CPU clock remains
the same 30ns clock period when system goes into
Doze/Suspend. The chipset generates the STPCLK
(stop clock) signal periodically to prevent CPU for
accepting clock from clock generator. For full power
on, the CPU can receive 66M count in one second. If
the Slow Clock Ratio is set to 50%, the CPU will only
receive 33M clock count in one second. This will
effectively reduce CPU speed as well as CPU power.

3.7 Load Setup Defaults
The "Load Setup Defaults" option loads optimized settings for optimum system
performance. Optimal settings are relatively safer than the Turbo settings.
We recommend you to use the Optimal settings if your system has large
memory size and fully loaded with add-on card (for example, a file server using
double-sided 8MB DIMM x4 and SCSI plus Network card occupying the PCI
and ISA slots).
Optimal is not the slowest setting for this mainboard. If you need to verify a
unstable problem, you may manually set the parameter in the "BIOS Features
Setup" and "Chipset Features Setup" to get slowest and safer setting.
3.8 Load Turbo Defaults
The "Load Turbo Defaults" option gives better performance than Optimal
values. However, Turbo values may not be the best setting of this mainboard
but these values are qualified by the AOpen RD and QA department as the
reliable settings especially if you have limited loading of add-on card and
memory size (for example, a system that contains only a VGA/Sound card and
two DIMMs).
3-28
AWARD BIOS
To attain the best system performance, you may manually set the parameters
in the "Chipset Features Setup" to get proprietary setting. Make sure that you
know and understand the functions of every item in Chipset Setup menu. The
performance difference of Turbo from Optimal is normally around 3% to 10%,
depending on the chipset and the application.

3. Execute A:> AX3L200
DO NOT turn off the power during FLASH PROCESS.
4. Reboot the system by turn off the power after flash is completed.
5. Reload the "BIOS SETUP DEFAULT" and reconfigure other items as
previous set. Save & Exit. Done!
Note: The upgrade of new BIOS will permanently
replace your original BIOS content after flashing.
