Overview
MX3ZA is a new generation Socket 370 based system board that utilizes Intel
82440ZX AGPset on Micro ATX PCI/ISA platform. This AGPset is designed
for Celeron PPGA CPU, and supports new architectures such as a high speed
AGP graphic port, SDRAM, Ultra DMA/33, Bus Master IDE and USB port. It
has two Dual in-line Memory Module (DIMM) slots that allow to install
SDRAMs and expand up to a maximum of 256MB. Also, MX3ZA uses a 2M bit
Flash ROM BIOS to reserve for future new functions.
In addition to the above features, MX3ZA also implements many special
features as follows.
Jumper-less Design Celeron VID signal and SMbus clock generator provide
CPU voltage auto-detection and allows the user to set the CPU frequency
through the CMOS setup, therefore no jumpers or switches are used. The
correct CPU information is saved into the EEPROM. With these technologies,
the disadvantages of the Pentium based jumper-less designs are eliminated.
There will be no worry of wrong CPU voltage detection and no need to re-open
the housing in case of CMOS battery loss. The only jumper left is to clear the
CMOS, which is a safety hook if you forget the password.
Battery-less Motherboard This motherboard implements EEPROM and a
special circuit (patent applied) that allows you to save your current CPU and
CMOS Setup configurations without the need of a battery. The RTC (real time
clock) can also keep running as long as the 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
VESA compatible PCI VGA, Sound Blaster compatible sound card with APM
driver, for Suspend to Hard Drive to work properly.

Overview
ACPI Suspend to Hard Drive The conventional "Suspend to Hard Drive"
function is a private design of AOpen motherboards, the requirement to run it
is a BIOS revision and correct chipset that supports this function. However,
nowadays "Suspend to Hard Drive" has been become widely known as the "S4
- Hibernation" state defined in the ACPI specification; in this case not only the
BIOS itself but also the operation system (i.e. Windows98) and even the
display card are involved in the execution of this function. With regard to how
to implement this function, please refer to section “1.4 ACPI Suspend to Hard
Drive”.
Zero Voltage Wake on Modem In conjunction with ATX soft power On/Off, it
is possible to have the system totally power off and wakeup to automatically
answer a phone call to serve as an answering machine or to send/receive a
fax. The most important break through is not only an externally cased modem
but also an internal modem card can be used to support Wake On Modem.
This motherboard and MP56 internal modem card implement a special circuit
(patent applied) to make sure the modem card works properly without any
power.
Wake On LAN This feature is very similar as the Wake On Modem feature, but
it is through a local area network. To use the Wake On LAN function, you must
have a network card that supports this feature and have installed proper
network management software.
Wake On RTC Timer The Wake Up Timer is more like an alarm, which
wakes up and powers on your system at a pre-defined time for a specific
application. It can be set to wake up everyday or on specific date within a
month. The date/time is accurate to within a second.
Wake On Keyboard This function allows you to 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 power on the system by clicking a
specified 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 settings if this item is set to
“Enabled” the system will automatically power-on after AC power resumes.
High Efficiency Synchronous Switching Regulator Most of the current
switching designs are Asynchronous mode, which from a technical point of
view, still consumes very high power and generates heat. This motherboard
implements a high efficient synchronous switching design so that the
temperature of MOS FET is far less than the Schottky diode of the
asynchronous design.
1-2
Overview
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. MX3ZA 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.
CPU and Housing Fan Monitoring This motherboard has one more "fan
monitoring" function to prevent system overheat. There are two fan connectors.
One is for the CPU and the other can be an extra housing fan. The system will
report an alarm fan malfunction through utility software such as Hardware
Monitoring Utility.
CPU Thermal Protection This motherboard has a special thermal detection
circuit to provide warning through application software when the temperature is
higher than a predefined value.
System Voltage Monitoring Further more, this motherboard implements a
voltage monitoring system. As you turn on your system, this smart design will
continue to monitor your system’s working voltage. If any of the system’s
voltage is over the component's standard an alarm will be sounded through
utility software such as a Hardware Monitoring Utility for a warning to user.
Resetable Fuse This motherboard implements resetable fuses to prevent any
accidental short circuit caused by keyboard or USB devices hot plug.
FCC DoC certificate MX3ZA has passed FCC DoC test. The radiation is very
low, you can use any kind of housing.
Powerful Utility Software AOpen Bonus Pack bundled CD contains many
useful utilities, such as Norton Antivirus, AOchip, Hardware Monitoring Utility,
and Suspend to Hard Drive Utility.
註解: Is this a specific
application that comes on
the driver disc? If so, then it
should be specified with the
word ‘the’ not ‘a’
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".

Overview
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. 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.

1.4 Zero Voltage Modem Wake Up
The Wake On Modem discussed here is to wakeup from true power off
(defined as the fan of power supply being off), This motherboard still supports
traditional green PC suspend mode but is not discussed here.
With the help of the ATX soft power On/Off, it is possible to have a 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 as an answering machine or to send/receive a fax. You
may identify whether or not your system is in true power off mode by checking
to see if the fan of your power supply is off. Both an external box modem and
an internal modem card can be used to support Modem Wake Up, but if you
use an external modem, you have to leave your box modem on. The AOpen
MX3ZA and internal modem card implement a special circuit (patent applied)
and make sure the modem card works properly without any power. We
recommend choosing the AOpen modem card (MP56) for Wake On Modem
applications.

Overview
1.5 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’s working
voltage. If any of the system’s voltage is over the component's standard there
will be an alarm through application software such as the Hardware Monitoring
Utility to warn the user. The system voltage monitoring function monitors CPU
core voltage. It is automatically implemented by the BIOS and Hardware
Monitoring Utility (the program’s file name is like aohwxxx.exe, where xxx
means the version number), no hardware installation is needed.
1.6 Fan Monitoring
There are three fan connectors, two is for CPU, the other can be connected to
a housing fan. The fan monitoring function is implemented by connecting fan
to 3-pin fan connector CPUFAN1 or FAN and installing Hardware Monitoring
Utility.
1-12
Note: You need a 3-pin fan that supports SENSE
signal for fan monitoring function to work
properly.
Overview
1.7 CPU Thermal Protection
This motherboard implements special thermal protection circuits. When
temperature is higher than a predefined value, there will be warning through
application software such as the Hardware Monitor utility to notify the user. It is
automatically implemented by the BIOS and the Hardware Monitoring Utility,
no hardware installation is needed.
1.8 Battery-less Design
To preserve the earth, this motherboard implements the battery-less
motherboard design. There is no need to have a battery for RTC (real time
clock) and CMOS Setup as long as the ATX power cable is plugged in. In case
the AC power is shutdown or the power cord is removed by accident, the
CMOS Setup and system configuration can be restored from EEPROM, only
the system clock needs to be re-set to current date/time.
For the convenience of the end user, the MX3ZA still ships with one Lithium
(CR-2032) battery. If you prefer to use a battery, you can still insert it into
battery socket. The RTC will still keep running even when the power cord is
removed.

2.2 Jumpers
With the help of VID signal and SMbus, this motherboard is jumper-less design.
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, 75, 83.3, 100, 103, 105, 110, 112, 120, 124, 133,
140, 150 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 350 350MHz= 3.5x 100MHz
Celeron PPGA 366 366MHz= 5.5x 66MHz
Celeron PPGA 400 400MHz= 6x 66MHz
Celeron PPGA 433 433MHz= 6.5x 66MHz
Warning: INTEL 440ZX chipset supports maximum 100MHz FSB
clock, the higher clock settings are for internal test only. These
settings exceed the specification of ZX chipset, which may
cause serious system damage.

Normal Operation
(default)
The procedure to clear CMOS:
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.
6. Turn on the system power.
7. Press
during bootup to enter the BIOS Setup Utility and specify a
new password, if needed.
Tip: If your system hangs or fails to boot because of overclocking, please clear CMOS and the system will go back to
default setting (300MHz).
Tip: If your system hangs or fails to boot because of overclocking, simply use <Home> key to restore to the default
setting (300MHz). By this smart design, it would be more
convenient to clear CPU frequency setting. For using this
function, you just need to press <Home> key first and then
