In one embodiment, the present invention includes a method for obtaining a pre-boot authentication (PBA) image from a non-volatile storage that is configured with full disk encryption (FDE), and storing the PBA image in a memory. Then a callback protocol can be performed between a loader executing on an engine of a chipset and an integrity checker of a third party that provided the PBA image to confirm integrity of the PBA image, the PBA image is executed if the integrity is confirmed, and otherwise it is deleted.
