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.
