VERIFYING BASIC INPUT/OUTPUT SYSTEM (BIOS) BOOT BLOCK CODE

Systems and methods for verifying Basic Input/Output System (BIOS) boot block code are described. In some embodiments, an Information Handling System (IHS) may include: a processor; a memory coupled to the processor, the memory comprising BIOS instructions stored thereon; and an embedded controller (EC) coupled to the memory, the EC configured to: after a power-on sequence of the IHS is initiated and before a power rail of the processor is turned on, unlock write access to the memory; perform an Error Correction Code (ECC) evaluation of a BIOS boot block code portion of the BIOS instructions; verify integrity of the BIOS boot block code portion; lock write access to the memory; and allow the processor to execute the BIOS instructions.
