Method and apparatus for secure execution of software prior to a computer system being powered down or entering a low energy consumption mode

摘要: A computer system that automatically and securely executes registered programs immediately prior to a transition reduced energy consumption state. registrar table specifying secure modification detection value for each program are maintained in management mode memory or other space the system. interrupt is generated following request remove power from occurrence of an event triggers saving mode. The handler routine then generates current program. values compared with values. Execution permitted if match. After all have been executed, powers down enters thereby allows convenient execution commands would typically interfere normal use.
