  • Page 16: Cpu Jumper-Less Design

    CPU VID signal and SMbus clock generator provide CPU voltage auto-detection and allows the user to set the CPU frequency through the BIOS 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.

  • Page 21: Dimm Socket

    This motherboard has three 168-pin DIMM sockets that allow you to install PC133 memory up to 1.5GB. Only SDRAM is supported. Tip: The driving capability of new generation chipset is limited due to the lack of a memory buffer (to improve performance).
  • Page 22 DIMM can be single side or double side, it has 64 bit data and 2 or 4 clock signals. We strongly recommend choosing 4-clock SDRAM for its reliability Tip: To identify 2-clock and 4-clock DIMM, you may check if there are traces connected to the golden finger pins 79 and 163 of the SDRAM.

  • Page 26: 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.

  • Page 31: Wom (Zero Voltage Wake On Modem)

    This motherboard implements special circuit to support Wake On Modem, both Internal modem card and external box modem are supported. Since Internal modem card consumes no power when system power is off, it is recommended to use an internal modem. To use internal modem, connect 4-pin cable from RING connector of modem card to the WOM connector on the motherboard.

  • Page 34: Wol (Wake On Lan)

    This feature is very similar as Wake On Modem, but it goes through local area network. To use Wake On LAN function, you must have a network card with chipset that supports this feature, and connect a cable from LAN card to motherboard WOL connector. The system identification information (probably IP address) is stored on network card and because there is a lot of traffic on the Ethernet, you need to install a network management software, such as ADM, for the checking of how to wake up the system.

    If the housing has been design with an audio port on the front panel, you’ll be able to connect onboard audio to front panel through this connector. By the way, please remove the jumper cap from the Front Panel Audio Connector before you connect the cable. Do not remove this yellow jumper cap if housing without an audio port on the front panel.

  • Page 44: Battery-Less And Long Life Design

    This Motherboard implements EEPROM and a special circuit 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.

  • Page 45: Over-Current Protection

    The Over Current Protection was very popular implemented on ATX 3.3V/5V/12V switching power supply. However, the new generation CPU uses different voltage that has regulator to transfer 5V to CPU voltage (for example, 2.0V), and makes 5V over current protection useless. This motherboard 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.
  • Page 46 CPU, memory, HDD, add-on cards installed on this motherboard may be damaged because of component failure, human operating error or unknown nature reason. AOpen cannot guaranty the protection circuit will always work perfectly.

  • Page 47: Hardware Monitoring

    This motherboard implements a hardware monitoring system. As you turn on your system, this smart design will continue to monitor your system’s working voltage, fan status and CPU temperature. If any of these system’s status go wrong, there will be an alarm through the AOpen Hardware Monitoring Utility to warn the user.

  • Page 48: Resettable Fuse

    Traditional motherboard has fuse for Keyboard and port to prevent over-current or shortage. These fuses are soldered onboard that when it is broken (did the job to protect motherboard), user still cannot replace it and the motherboard is still malfunction. With expensive Resettable Fuse, the motherboard can back to normal function after fuse did the protection job.

  • Page 49: Year 2000 (Y2K)

    Y2K is basically a problem of the identification of year code. To save storage space, traditional software uses only two digits for year identification. For example, 98 for 1998 and 99 for 1999, but 00 will be confused with 1900 and 2000. There is an RTC circuit (Real Time Clock) in conjunction with 128 bytes of CMOS RAM data in the chipset of the motherboard.
  • Page 50 CMOS is a very slow device which degrades system performance. The Tick Routine of the AOpen BIOS has 4 digits for year coding, as long as applications and the operating system follow the rule to get date/time information. There will be no Y2K problem (such as NSTL’s test program).

  • Page 51: 1500Uf Low Esr Capacitor

    The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency operation is very important for stability of CPU power. The location of where to put these capacitors is another know-how that requires experience and detail calculation. Not only that, this motherboard implements Low ESR capacitors, which is much larger than normal (1000uF) and provide better stability for CPU power.
  • Page 52 The power circuit of the CPU core voltage must be checked to ensure system stability for high speed CPUs (such as the new Pentium III, or when overclocking). A typical CPU core voltage is 2.0V, so a good design should control voltage between 1.860V and 2.140V. That is, the transient must be below 280mV.

  • Page 53: Layout (Frequency Isolation Wall)

    For high frequency operation, especially overclocking, layout is the most important factor to make sure chipset and CPU working in stable condition. The layout of this motherboard implements AOpen’s unique design called “ Frequency Isolation Wall”. Separating each critical portion of motherboard into regions where...

  • Page 54: Driver And Utility

    There are motherboard drivers and utilities included in AOpen Bonus CD disc. You don’t need to install all of them in order to boot your system. But after you finish the hardware installation, you have to install your operation system first (such as Windows 98) before you can install any drivers or utilities.

  • Page 77: Overclocking

    As a leading manufacturer in motherboard industry, AOpen always listens to what customers want and develop products to fit different user's requirements. Reliability, compatibility, leading technology and friendly features are our basic goals when designing motherboards. Other than above mentioned design criteria, there are power users who are always seeking to push the limitation of the system performance by overclocking which we call them "Overclocker".
  • Page 78 Warning: The design of this product follows CPU and chipset vendor's design guideline. Any attempts to push beyond product specification are not recommended and you are taking your own risk to damage your system or important data. Before doing overclocking, you must make sure your components are able to tolerate such abnormal setting, especially CPU, memory, hard disks, and AGP VGA cards.
