Chapter 1
Overview
MX64 is a slot 1 based motherboard that utilizes VIA 694X AGPset on Micro
ATX form factor. It implements an onboard audio CODEC and supports new
architectures such as AGP 4x, SDRAM, Ultra DMA 33/66, Bus master IDE
and USB ports. It supports three Dual in-line memory module (DIMM) slots
that allow the installation of SDRAM memory and expansion up to a maximum
of 768MB.
In addition to the above features, MX64 also implements plenty of fabulous
features.
Jumper-less Design Pentium II / Pentium III / 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.
Full-range CPU core voltage This motherboard supports the CPU core
voltage from 1.3V to 3.5V, that can be applied to various CPU type in future.
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 0V Wake On Modem. The MX64 and
FM56-P 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 0V 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.
CPU Thermal Protection MX64 has a special thermal detection circuit to have
warning through application software when the temperature is higher than a
predefined value.
CPU and Housing Fan Monitoring MX64 has one more "fan monitoring"
function to prevent system overheat. The system will report and alarm fan
malfunction though utility software such as Hardware Monitoring Utility (named
AOhw140, where 140 means version number).
System Voltage Monitoring Furthermore, MX64 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 software such as
Hardware Monitoring Utility for a warning to user.
ACPI Suspend to DRAM You can resume your original work directly from
DRAM without going through the Win98 booting process and run your
application again. Suspend to DRAM saves your current work into the system
memory.
Resetable Fuse MX64 implements resetable fuses to prevent any accidental
short circuit caused by keyboard or USB devices hot plug.
FCC DoC Certificate MX64 has passed FCC DoC test. The radiation is very
low, you can use any kind of housing.
PC99 Ready For user’s convenience in installing the PC system, AOpen
adopts the recommended PC99 color scheme in all connectors that mount on
this motherboard.
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.

1.2 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 0V
Wake On Modem, but if you use external modem, you have to keep the box
modem always power-on. AOpen MX64 and internal modem card implement
special circuit (patent applied) and make sure the modem card works properly
without any power. We recommend you choose AOpen modem card (For
example, FM56-P, FM56-H, etc.) for 0V Wake On Modem applications.

For Internal Modem Card (AOpen FM56-P):
1. Go into BIOS setup, Power Management Æ0V Wake On Modem, select
Enabled.
2. Setup your application, put into Windows 95.
3. Turn system power off by soft power switch.
4. Connect 4-pin Modem Ring-On cable from FM56-P RING connector to
MX64 connector WKUP.
5. Connect telephone line to FM56-P. You are now ready to use Wake On
Modem.
For External Box Modem:
1. Go into BIOS setup, Power Management Æ0V Wake On Modem, select
Enabled.
2. Setup your application, put into Windows 95 Start Up.
3. Turn system power off by soft power switch.
4. Connect RS232 cable of external box Modem to COM1 or COM2.
5. Connect telephone line to external box Modem. Turn on Modem power
(you must keep Modem power always on). You are now ready to use Wake
On Modem.
Tip: External 0V Wake On Modem signal is detected
through COM1 or COM2. Internal modem card wake up
signal is detected through cable from connector RING
(on modem card) to WKUP (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.

1.3 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
will be alarm through application software such as Hardware Monitor utility for
a warning to user. System voltage monitoring function monitors CPU core
voltage. It is automatically implemented by BIOS and Hardware Monitor utility
(the file name is like aohw100.exe, where 100 means the version number, no
hardware installation is needed.
1.4 Fan Monitoring
There are three fan connectors, two is for CPU, the other can be a housing fan.
The fan monitoring function is implemented by connecting fan to 3-pin fan
connector CPUFAN1 and FAN,and installing Hardware Monitoring Utility.
Note: You need 3-pin fan that supports SENSE
signal for fan monitoring function to work
properly.

1.5 CPU Thermal Protection
This motherboard implements special thermal protection circuit below the CPU.
When temperature is higher than a predefined value, the CPU speed will
automatically slow down and there will be warning from BIOS and also
Hardware Monitoring Utility software.
CPU Thermal Protection is automatically implemented by BIOS and utility
software, no extra hardware installation is needed.

Hardware Installation
This chapter gives you a step-by-step procedure on how to install your system.
Follow each section accordingly.
Caution: Electrostatic discharge (ESD) can
damage your processor, disk drives, expansion
boards, and other components. Always
observe the following precautions before you
install a system component.
1. Do not remove a component from its
protective packaging until you are ready
to install it.
2. Wear a wrist ground strap and attach it to
a metal part of the system unit before
handling a component. If a wrist strap is
not available, maintain contact with the
system unit throughout any procedure
requiring ESD protection.
