ABSTRACT:
A system management mode (SMM) of operating a processor includes only a basic set of hardwired hooks or mechanisms in the processor for supporting SMM. Most of SMM functionality, such as the processing actions performed when entering and exiting SMM, is "soft" and freely defined. A system management interrupt (SMI) pin is connected to the processor so that a signal on the SMI pin causes the processor to enter SMM mode. SMM is completely transparent to all other processor operating software. SMM handler code and data is stored in memory that is protected and hidden from normal software access.
