  • Page 35: Wom (Zero Voltage Wake On Modem) Connector

    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.

You may identify whether or not your system is in true power off mode by checking to see if the fan of your power supply is off.

  • Page 38: 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 a 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 in network card and because there is a lot of traffic on the Ethernet, you need to install network management software, such as ADM, to check how to wake up the system.

  • Page 47: Battery-Less And Long Life Design

    This Motherboard implements Flash ROM and a special circuit that allows you to save your current CPU and CMOS Setup configurations without using the 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 Flash ROM and the system will recover as usual.

  • Page 48: Over-Current Protection

    There is still certain risk that CPU, memory, HDD, and add-on cards installed on this motherboard may be damaged because of component failure, human operating error or other unknown reasons. AOpen cannot guarantee the protection circuit will always work perfectly.

  • Page 49: 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 systems’ status goes wrong, there will be an alarm through the AOpen Hardware Monitoring Utility to warn the user.

  • Page 50: Resettable Fuse

    Traditional motherboard has fuse for Keyboard and port to prevent over-current or shortage. These fuses are soldered onboard that user cannot replace when they are damaged (in order to protect motherboard), and the motherboard will remain malfunction. Equipped with expensive Resettable Fuses, this motherboard can resume back to normal function after fuses had done their protection job.

  • Page 51: 2200 Μf Low Esr Capacitor

    μ μ μ μ f f f f μ μ μ μ f f f f The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency operation is very important for the stability of CPU power. The idea of where to put these capacitors is another know-how that requires experience and detail calculation.
  • 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 4, or when overclocking). A typical CPU core voltage is 2.0V, so a good design should control voltage between 1.860V and 2.140V.

  • Page 53: Layout (Frequency Isolation Wall)

  • Page 73: Ata/100

    ATA/100 is a new IDE specification under developing. ATA/100 uses both rising edge and falling edge as ATA/66 but clock cycle time is reduced to 40ns. The data transfer rate is (1/40ns) x 2 bytes x 2 = 100MB/s. To use ATA/100, you need special 80-wire IDE cable, the same as ATA/66.

  • Page 74: Codec (Coding And Decoding)

    Normally, CODEC means a circuit that can do digital to analog conversion and also the analog to digital conversion. It is part of AC97 sound/modem solution. DDR SDRAM utilizes the existing SDRAM infrastructure and technology while doubling the nominal bandwidth available to systems in an easy to design and simple to adopt way.

  • Page 75: Ecc (Error Checking And Correction)

    The ECC mode needs 8 ECC bits for 64-bit data. Each time memory is accessed; ECC bits are updated and checked by a special algorithm. The ECC algorithm has the ability to detect double-bit error and automatically correct single-bit error while parity mode can only detect single-bit error.

  • Page 76: Ev6 Bus

    Flash ROM can be re-programmed by electronic signals. It is easier for BIOS to upgrade by a flash utility, but it is also easier to be infected by virus. Because of increase of new functions, BIOS size is increased from 64KB to 256KB (2M bit). AOpen AX5T is the first board to implement 256KB (2Mbit) Flash ROM.
