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 Intel
®
Low Pin Count Specification
Rev. 1.1. 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
IrDa 1.0 and ASKIR protocols
2.8.3.3 Super I/O Hardware Monitor
The Super I/O Hardware Monitor monitors three thermal inputs, VBAT internally, and eight
voltage monitor inputs. The Super I/O Hardware Monitor supports the SmartFan® control
system, including the “Thermal Cruise™” and “Speed Cruise™” functions. 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.
