14. A method for verifying a provisioning sequence of Basic Input/Output System (BIOS) modules, comprising:
providing, by a Basic Input/Output System (BIOS) subsystem, a plurality of BIOS modules in a BIOS module provisioning sequence using a plurality of firmware volumes included in a BIOS storage system and, for each of the plurality of BIOS modules when that BIOS module is provided during the BIOS module provisioning sequence:
retrieving a BIOS module identifier associated with that BIOS module; and
updating BIOS module provisioning sequence information using that BIOS module identifier; and
providing, by the BIOS subsystem following the provisioning of the BIOS modules in the BIOS module provisioning sequence, the BIOS module provisioning sequence information to a Trusted Platform Module (TPM), wherein the BIOS module provisioning sequence information is configured to be compared to BIOS module provisioning sequence verification information to verify the BIOS module provisioning sequence.
