Abstract
A system and method for BIOS flash attack protection and notification. A processor initialization module, including initialization firmware verification module may be configured to execute first in response to a power on and/or reset and to verify initialization firmware stored in non-volatile memory in a processor package. The initialization firmware is configured to verify the BIOS. If the verification of the initialization firmware and/or the BIOS fails, the system is configured to select at least one of a plurality of responses including, but not limited to, preventing the BIOS from executing, initiating recovery, reporting the verification failure, halting, shutting down and/or allowing the BIOS to execute and an operating system (OS) to boot in a limited functionality mode.
