Abstract
A method, apparatus, machine-readable medium, and system are disclosed. In one embodiment the method includes a processor. The processor includes switching a platform firmware update mechanism located in a computer platform to a platform firmware armoring technology (PFAT) mode on a boot of the computer platform. The computer platform includes a platform firmware storage location that stores a platform firmware. The method then persistently locks the platform firmware storage location in response to the platform firmware update mechanism switching to the PFAT mode. When persistently locked, writes are only allowed to the platform firmware storage location by an Authenticated Code Module in the running platform and only after a platform firmware update mechanism unlocking procedure.
