Some of the Super I/O features are described in more detail below:
2.7.2.1 Super I/O LPC Interface
The LPC interface on the Super I/O complies with the Intel® Low Pin Count Specification
Rev. 1.0. The LPC interface supports both LDRQ# and SERIRQ protocols as well as PCI
PME# interfaces.
2.7.2.2 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
2.7.2.3 Super I/O Smart Fan Control System
The Super I/O Smart Fan Control System enables the system to monitor the speed of the
fan. Thermal Cruise™ monitors the CPU temperature and adjusts the fan to keep the
temperature within the chosen range. Speed Cruise™ monitors the fan speed and adjusts
it to stay within the chosen range.
2.7.2.4 Super I/O Floppy Disk Drive (FDD) Controller
The Super I/O FDD controller is compatible with the following specifications.
IBM PC AT disk drive compatible
Variable write pre-compensation with track selectable capability
Vertical recording format supported
DMA logic enabled
