Abstract
Verification of a primary or backup copy of vital information of a processing system employs a pseudo-fixed reference identifier, defined as an identifier unlikely to change over the life of the system, and controls which copy of vital information is correct. The primary copy of vital information is associated with a copy of the pseudo-fixed reference identifier and a backup copy of the vital information is associated with a copy of the pseudo-fixed reference identifier. A processor, when triggered, reads the pseudo-fixed reference identifier, compares it to the stored copies of the identifier of the primary and backup non-volatile storage. ( ) If the read pseudo-fixed reference identifier matches the primary copy of the identifier, the processor indicates the vital information is valid. ( ) If the read pseudo-fixed reference identifier matches the backup only, indicating that the backup copy of vital information is to be restore copied to become the primary copy.
