Methods and systems for Basic Input/Output System BIOS processing such as hashing are disclosed. In one embodiment, there is a direct interface between a security module and a non-volatile memory storing the BIOS in a computing system so that the security module may directly access the BIOS without using the central processing unit CPU as an intermediary. In one embodiment, the security module is powered by standby power and therefore can begin BIOS processing even if the computing system has not yet been turned on.
