  • Hardware independent implementation of computer system BIOS recovery
    Patent number: 6757838
    Abstract: Either a backup BIOS or a main BIOS in a non-volatile memory is used to fully boot a computer system, depending on the validity of the main BIOS, successful prior booting using the main BIOS, or the validity of the CMOS settings. Unlike the boot block procedure, in either case, the computer system becomes fully operational. A count is made indicating the number of times booting is retried with the main BIOS. If a predetermined count value is reached, the main BIOS is invalid, or CMOS is invalid, then booting is completed using the backup BIOS. If the predetermined count value is not reached, a jump is made from the end of the BIOS validation code to an entry point in the main BIOS of the non-volatile memory to continue booting using the main BIOS. The backup BIOS is stored in a permanent protected portion of the non-volatile memory and the main BIOS is stored in a flashable portion of the non-volatile memory.
