Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system sus-
pend button to make the system enter a SoftOff state. The monitor will be suspended
and the hard drive will spin down. Pressing the power button again will cause the
whole system to wake-up. During the SoftOff state, the ATX power supply provides
power to keep the required circuitry in the system “alive.” In case the system mal-
functions and you want to turn off the power, just press and hold the power button
for 4 seconds. This option can be set in the Power section of the BIOS Setup routine.

Wake-on-LAN (WOL)
Wake-On-LAN is defined as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, up-dates and asset track-
ing can occur after hours and on weekends so that daily LAN traffic is kept to a min-
imum and users are not interrupted. The motherboard has a 3-pin header (WOL) to
connect to the 3-pin header on a Network Interface Card (NIC) that has WOL capa-
bility. In addition, an onboard LAN controller can also support WOL without any
connection to the WOL header. The 3-pin WOL header is to be used with a LAN
add-on card only.

Super I/O
The Super I/O supports 360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data
transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s. It also provides two high-speed,
16550 compatible serial communication
ports (UARTs). Each UART includes a 16-byte
send/receive FIFO, a programmable baud rate generator, complete modem control capability and a
processor interrupt system. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps
as
well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which sup-
port higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Configuration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through an SMI or SCI function pin. It also features auto power management to
reduce power consumption.
