SMBus
Last modified: Thursday, February 09, 2006 

The System Management Bus (SMBus) is a two-wire interface through which simple power-related chips can communicate with rest of the system. It uses I2C as its backbone. With the SMBus, a device can provide manufacturer information, tell the system what its model or part number is, save its state for a suspend event, report different types of errors, accept control parameters and return its status.
