  • System and method for providing a secure boot architecture
    Publication number: 20060179308
    Abstract: A system and method for providing a secure boot architecture, in accordance with one embodiment of the present invention, includes a processor having an atomic state machine and a physically protected storage area. The atomic state machine stores a state of the processor in a state save map upon a boot-mode event. The atomic state machine also authenticates an object of a Pre-BIOS Boot Vector Region (PBBVR) in response to the boot-mode event. The PBBVR may be stored in the physically protected storage area. The atomic state machine loads the PBBVR from the physically protected storage area into an overlay memory if the PBBVR is successfully authenticated. The processor executes the PBBVR from the overlay memory if the PBBVR is successfully authenticated.
