X11SAE-M User's Manual

1.6 Power Supply

As with all computer products, a stable power source is necessary for proper and reliable
operation. It is even more important for processors that have high CPU clock rates. In areas
where noisy power transmission is present, you may choose to install a line filter to shield
the computer from noise. It is recommended that you also install a power surge protector to
help avoid problems caused by power surges.

1.7 Super I/O

The Super I/O NUVOTON NCT6776D chip provides one high-speed, 16550 compatible
serial communication port (UART), which supports serial infrared communication. The UART
includes a 16-byte send/receive FIFO, a programmable baud rate generator, complete modem
control capability and a processor interrupt system. The UART provide legacy speed with a
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 support 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 management through a SMI
or SCI function pin. It also features auto power management to reduce power consumption.
The IRQs, DMAs and I/O space resources of the Super I/O can be flexibly adjusted to meet
ISA PnP requirements, which support ACPI and APM (Advanced Power Management).

1.8 Advanced Power Management

The following new advanced power management features are supported by the motherboard.

Management Engine (ME)

The Management Engine, which is an ARC controller embedded in the IOH (I/O Hub), provides
support for VPRO with ME11.
