4. e it is in sleep mode This feature is particularly usefully when you are expecting a fax late night and leave only your modem on to minimize power consumption As soon as possible the phone rings the modem automatically turn on the system which answers the phone and downloads the fax Then the computer shuts off again thereby minimizing its consumption of power The Remote Ring On function requires a power supply with a soft off power controller B RTC Alarm The RTC alarm feature allows you to preset the computer to wake up at a certain time allowing you to implement a number of useful functions such as automatically sending out a fax late at night
5. flexibility the motherboard also supports other leading edge processors featuring MMX technology including the AMD K6 Cyrix 6X86MX IBM 6x86MX processors BI Onboard Accelerated Graphics Port AGP The motherboard is installed one 32 bit AGP bus with a dedicated 66MHz 133MHz path from the graphics card to the system memory by 1x 2x mode offering much greater bandwidth than the 32 bit PCI bus does which currently operates at a speed of 33MHz and is fully compliant with the AGP 1 0 specification AGP enabled 3D graphics cards can directly access main memory across this fast path instead of using local memory To make use of the improved AGP performance the motherboard should be installed with SDRAM type memory and the VGA card and drivers should also be fully AGP compliant Using Microsoft Windows 98 and Windows NT 5 0 which implement DirectDraw will allow the system to take full use of AGP benefits without the need to install additional drivers E CPU Thermal Monitoring Alert An optional EISCA CPU fan with a heat sensor monitors the CPU temperature to make sure that the system is operating at a safe heat level When the temperature is overheat the system warns you that the CPU is overheating CPU utilization is restored to normal levels when the temperature returns to a safe level This feature requires a power supply with a soft off power controller B6 Lightning Fast SDRAM Performance The motherboard supports general 66MHz and the new ge
6. neration of lightning fast 100MHz SDRAM via its onboard 168 pin DIMM sockets SDRAM delivers an added boost to overall system performance by increasing the CPU to memory data transfer rate SDRAM performance on the VA 503 is further boosted by the board integrated IC controller which optimizes the memory timing settings VA 5034 Motherboard Manual ACPI Ready This motherboard fully implements the new ACPI Advanced Configuration and Power Interface 1 0 Hardware and BIOS requirement If you install ACPI aware operating system such as Windows 98 you fully utilized the power saving under ACPI It is compatible with all other none ACPI operating systems If you want to setup ACPI feature under Windows 98 please follow the description below Run Windows 98 setup by using setup p j on the command line for installing Windows 98 with the ACPI control feature If you type setup without the parameter p j Windows 98 will be installed as APM PnP mode no ACPI will be used For more detail information please visit the web site of Microsoft Its address is www microsoft com hwtest The following lists a few examples about the advantages of ACPI E Soft Off Support The motherboard Soft Off feature allows you to turn off your computer using the operating system This feature requires a power supply with a soft off power controller E Remote Ring On The Remote Ring On function allows your computer to be turned on remotely via a modem whil
