ABSTRACT:
The disclosed embodiments relate generally to providing cost-effective data integrity in computer systems and, more particularly, to providing a back-up for system firmware in a BIOS-accessible pre-boot environment. Back-up copies of a system BIOS or other firmware are placed on a partition that is accessible to the system BIOS prior to system boot. The back-up copy may be retrieved and loaded if the system BIOS becomes corrupted. Multiple back-up versions may be stored on the partition.
