  • Publication number: 20240134631
    Abstract: An information handling system includes a memory and a processor. The memory stores a current basic input/output system (BIOS) firmware image. During a regular boot mode of the information handling, the processor creates a first set of tables associated with the current BIOS firmware image, stores the first tables to the memory, and receives a BIOS firmware update image. During a BIOS update boot mode of the information handling system, the processor creates a second plurality of tables associated with the BIOS firmware update image, and compares the first and second tables. In response to a difference being determined between the first and second tables, the processor aborts the BIOS update boot mode and generate an error log.
