Overview
VESA compatible PCI VGA, Sound Blaster compatible sound card with APM
driver, for Suspend to Hard Drive to work properly.
Zero Voltage Wake on Modem 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 Wake On Modem. The AX3L and MP56
internal modem card implement special circuit (patent applied) to make sure
the modem card work properly without any power.
Wake on LAN This feature is very similar as Wake On Modem, but it is
through local area network. To use Wake on LAN function, you must have a
network card that supports this feature and also need to install a network
management software.
Wake on RTC 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 accuracy is second.
Wake on Keyboard This feature allows you 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 wake up the system by clicking
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 setting the item to Enabled lets
the system can 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. AX3L 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
over current protection useless. AX3L 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.
