Overview
ACPI Suspend to Hard Drive The conventional "Suspend to Hard Drive"
function is a private design of AOpen motherboards, the requirement to run it
is a BIOS revision and correct chipset that supports this function. However,
nowadays "Suspend to Hard Drive" has been become widely known as the "S4
- Hibernation" state defined in the ACPI specification; in this case not only the
BIOS itself but also the operation system (i.e. Windows98) and even the
display card are involved in the execution of this function. With regard to how
to implement this function, please refer to section "1.4 ACPI Suspend to Hard
Drive".
Zero Voltage Wake on Modem In conjunction with ATX soft power On/Off, it
is possible to have the system totally power off and wakeup to automatically
answer a phone call to serve as an answering machine or to send/receive a
fax. The most important break through is not only an externally cased modem
but also an internal modem card can be used to support Wake On Modem.
This motherboard and MP56 internal modem card implement a special circuit
(patent applied) to make sure the modem card works properly without any
power.
Wake On LAN This feature is very similar as the Wake On Modem feature, but
it is through a local area network. To use the Wake On LAN function, you must
have a network card that supports this feature and have installed proper
network management software.
Wake On RTC Timer The Wake Up Timer is more like an alarm, which
wakes up and powers on your system at a pre-defined time for a specific
application. It can be set to wake up everyday or on specific date within a
month. The date/time is accurate to within a second.
Wake On Keyboard This function allows you to 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 power on the system by clicking a
specified 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 settings if this item is set to
"Enabled" the system will automatically power-on after AC power resumes.
High Efficiency Synchronous Switching Regulator Most of the current
switching designs are Asynchronous mode, which from a technical point of
view, still consumes very high power and generates heat. This motherboard
implements a high efficient synchronous switching design so that the
temperature of MOS FET is far less than the Schottky diode of the
asynchronous design.
