Overview
compatible PCI VGA, Sound Blaster compatible sound card with APM driver,
for Suspend to Hard Drive to work properly.
Zero Voltage Modem Wake Up 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 Modem Wake Up. The AX6BC and MP56
internal modem card implement special circuit (patent applied) to make sure
the modem card work properly without any power.
LAN Wake Up This feature is very similar as Modem Wake Up, but it is through
local area network. To use LAN Wake Up function, you must have a network
card that supports this feature and also need to install a network management
software.
RTC Wake Up 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 accurate is second.
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. AX6BC implements high
efficient synchronous switching design that the temperature of MOS FET is far
less than Schottky diode of asynchronous design.
Over Current Protection Circuit The Over Current Protection was very
popular implemented on the Baby AT or ATX 3.3V/5V/12V switching power
supply. But unfortunately, the new generation Pentium II CPU uses different
voltage that have regulator to transfer 5V to CPU voltage (for example, 2.8V),
and make 5V over current protection useless. AX6BC 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 AX6BC has one more "fan monitoring"
function to prevent system overheat. There are two fan connectors, one is for
CPU and the other can be an extra housing fan. The system will report and
alarm fan malfunction though utility software such as Hardware Monitor utility
(Small Icon for Hardware Monitoring).
CPU Thermal Protection AX6BC 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, AX6BC 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
