AUTOMATED MODULAR AND SECURE BOOT FIRMWARE UPDATE

摘要

PURPOSE: A method for updating secure boot firmware is provided to improve a BIOS/platform firmware monolithic image update process and allow the modularizing of firmware and secure update. CONSTITUTION: A processor(110) executes a boot firmware code module for a host operating system and a system. A secure partition is combined in the processor and separated from the host operating system. A receiving mean receives the updated boot firmware code module to the secure partition. An alternative mean automatically replaces the original boot firmware code module with the updated boot firmware code module. An execution mean automatically executes the updated boot firmware code module.
