Abstract
A boot program held in a BIOS memory device of a processing system is authenticated. At system start-up, a BIOS protection device temporarily prevents execution of the boot program by the central processor of the processing system by control of address and data paths. The BIOS protection device interrogates the contents of the BIOS memory device to establish authentication. If the contents of the BIOS memory device are not authentic, execution of the boot program is prevented.
