probe_it8712f is little tool that dumps register values of superio ITE it8712f.

Typically a superio can be found on port 2e or port 4e. This may change from
mainboard to mainboard. Register values of ff indicate that no superio is 
responding to the IO reads.

The default values have been taken from the IT8712F datasheet. The name of the 
document is 495234_DS.pdf.
