SMM SMI
System Management Mode (SMM) is intended to be used for advanced power-management features and other operating-system-independent functions. The chipset is programmed to recognize many types of events and timeouts. When such an event occurs, the chipset asserts the SMI# input pin. At the next instruction boundary, the microprocessor saves its entire state and enters SMM.
