Superiotool

Superiotool is a GPL'd user-space helper tool for coreboot development purposes (but may also be useful for other things). It allows you to detect which Super I/O you have on your mainboard, and it can provide detailed information about the register contents of the Super I/O.

This utility should work on most modern UNIX-like operating systems; it has been tested on at least Linux and FreeBSD.
