Some of the Super I/O features are described in more detail below:

2.8.3.1 Super I/O LPC Interface

The LPC interface on the Super I/O complies with the Low Pin Count Specification Rev.

1.0. The LPC interface supports both LDRQ# and SERIRQ protocols as well as PCI PME#

interfaces.

2.8.3.2 Super I/O 16C550 UARTs

The onboard Super I/O has two integrated 16C550 UARTs that can support the following:

Two standard serial ports (COM1 and COM2)

IrDa 1.0 and ASKIR protocols

2.8.3.3 Super I/O Enhanced Hardware Monitor

The Super I/O Enhanced Hardware Monitor monitors three thermal inputs, VBAT

internally, and eight voltage monitor inputs. These hardware parameters are reported in

the BIOS and can be read from the BIOS Hardware Health Configuration menu.

2.8.3.4 Super I/O Fan Speed Controller

The Super I/O fan speed controller enables the system to monitor the speed of the fan.

One of the pins on the fan connector is reserved for fan speed detection and interfaced to

the fan speed controller on the Super I/O. The fan speed is then reported in the BIOS.

2.8.3.5 Super I/O Keyboard and Mouse Controller

The Super I/O keyboard and mouse controller is compatible with the following

specifications.

8042 compatible

Asynchronous access to two data registers and one status register
