Chapter 1 Overview MX3W is a new generation Socket 370 based system board that utilizes Intel 810 AGPset on Micro ATX PCI/ISA platform. This AGPset is designed for Celeron PPGA CPU, and supports new architectures such as high speed AGP graphic port, PC100 SDRAM, AMR slot, Ultra DMA 33/66, Bus master IDE, PCI 2.2 and USB port. It has two Dual in-line Memory Module (DIMM) slots that allow to install PC100 SDRAMs and expand up to a maximum of 512MB. Also, MX3W uses 4M bit Flash ROM BIOS to reserve for future new functions. In addition to the above features, MX3W also implements many special features as follows. Jumper-less Design Celeron PPGA 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 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. 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. 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 1-1 Overview - 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 "1.3 ACPI Suspend to Hard Drive". 0V 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, such as ADM. 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 Efficient Synchronous Switching Regulator Most of the current switching designs are Asynchronous mode, which from the technical point of view, still consumes very high power as well as heat. MX3W implements high efficient synchronous switching design that the temperature of MOS FET is far less than Schottky diode of asynchronous design. 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 1-2 Overview over current protection useless. MX3W 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 MX3W has a special thermal detection circuit to have warning through application software when the temperature is higher than a predefined value. System Voltage Monitoring Further more, MX3W 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 utility software such as Hardware Monitor utility (Small Icon for Hardware Monitoring) for a warning to user. Full-range CPU core voltage This motherboard supports the CPU core voltage from 1.3V to 2.05V, that can be applied to various CPU type in future. Resetable Fuse This motherboard implements resetable fuses to prevent any accidental short circuit caused by keyboard or USB devices hot plug. FCC DoC certificate MX3W has passed FCC DoC test. The radiation is very low, you can use any kind of housing. 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. 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.
