Abstract: A protected boot sequence in a computer system. A reset vector directs the system to a boot program including a protected program. This protected program verifies the integrity of the BIOS contents before branching to the BIOS for execution of normal bootstrap functions. The protected program can also lock down various blocks of bootstrap code to prevent them from being changed after a certain point in the boot sequence.
