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.

Overview
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.

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.

2.2 Jumpers
With the help of the Pentium II Pentium III / Celeron VID signal and SMbus, this
motherboard is a jumper-less design.
2.2.1 Selecting the CPU Frequency
The Pentium II \ Pentium III \ Celeron VID signal and the SMbus clock
generator provide CPU voltage auto-detection and allow the user to set CPU
frequency through the CMOS setup, no jumpers or switches are needed. The
correct CPU information is saved into the EEPROM. With these technologies,
the disadvantages of the Pentium based jumper-less design are eliminated.
There will be no worry of wrong CPU voltage detection and no need to re-open
the housing if the CMOS battery is lost.
The CPU frequency selection is set by going into:
BOIS Setup à Chipset Features Setup à CPU Clock Frequency
(The possible setting is 66.8, 75, 83.3, 100, 105, 110, 112, 115, 120, 124, 133,
140, 150, MHz)
BOIS Setup à Chipset Features Setup à 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,

Tip: If your system hangs or fails to boot because of overclocking, simply use <Home> key to restore to the default
setting. Press <Home> key and the power button at the same
time. Note that do not release <Home> key until POST screen
appears.
Warning: the VIA 694X chipset supports a maximum of 133MHz
FSB. The higher clock settings are for internal testing only. These
settings exceed the specification of the chipset, which may
cause serious system damage.
2.2.2 Setting the CPU Voltage
This motherboard supports the Pentium II / Pentium III / Celeron VID function,
the CPU core voltage is automatically detected and ranged from 1.3V to 3.5V.

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, simply use the <Home> key to restore the default
setting (233MHz). By this smart design, it would be more
convenient to clear CPU frequency setting. For using this
function, you just need to press the <Home> key first and
then press the Power button at the same time. Note: do not
release the <Home> key until the POST screen appears.

2.4 Configuring the System Memory
The DIMM type supported is SDRAM
(Synchronous DRAM), Registered
SDRAM and Virtual Channel Memory.
This motherboard has three 168-pin
DIMM sockets (Dual-in-line Memory
Module) that allow you to install system
memory up to 768MB.
Warning: This motherboard does not support EDO
DRAM.
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
single-side 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 single-side. Following figure is for
your reference.
Pin 129
Pin 114
II. Speed: Normally marked as -12, which means the clock cycle time is 12ns
and the maximum clock of this SDRAM is 83MHz. Sometimes you can also
find the SDRAM marked as -67, which means maximum clock is 67MHz.
2-16
Hardware Installation
Caution: Some SDRAMs marked as -10 may work
fine with 100 MHz CPU clock, but not all of this kind
of modules can work properly under 100MHz
external clock. We suggest you choose and install
SDRAMs that match PC 100 specification if 100MHz
or above CPU clock is selected.
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. The following figure is for your
reference:
Reserved
non-buffered
buffered
Because the positions are different, only non-buffered DIMMs can be
inserted into the DIMM sockets on this motherboard. Although most DIMMs
available in the current market are non-buffered, we still recommend you
ask your dealer for the correct type.
IV. 2-clock and 4-clock signals: Although both 2-clock and 4-clock signals
are supported by this motherboard, we strongly recommend you choose 4clock SDRAM for its reliability.
Tip: To identify 2-clock and 4-clock SDRAM, you may
check if there are traces connected to the golden finger
pins 79 and 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.
VI. SPD support: The BIOS will automatically detect DIMMs with SPD, and set
to the appropriate timing. DIMMs without SPD are still able to work fine on
this board, but the BIOS POST screen will give you a warning message that
you use a DIMM without SPD.
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 all of
them added together.
2-17
