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. 1-1 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.

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. TEL Line COMport External Box Modem External Modem Wake Up TEL Line Internal Modem Card Wake Up (such as FM56- P) 1-4 Overview For Internal Modem Card (AOpen FM56-P): 1.
