  • System and method for automated BIOS recovery after BIOS corruption
    Patent number: 11182148
    Abstract: A method includes determining that initial boot block (IBB) firmware at an information handling system is invalid. The method further includes identifying that a redundant copy of the IBB firmware is stored at the information handling system, and executing the redundant copy of the IBB firmware.
    Type: Grant

  • Method and apparatus for UEFI firmware boot journal recording
    Patent number: 10776131
    Abstract: An information handling system includes a flash memory and a processor. The processor executes boot instructions including a boot log agent configured to collect initialization phase messages. The flash memory device also includes a circular buffer configured to store the collected initialization phase messages.

  • System and method for operating system initiated firmware update via UEFI applications
    Patent number: 10459742
    Abstract: An information handling system includes a memory and a central processor. The memory stores a firmware update for a component of the information handling system. The central processor is operable in a pre-boot mode and in an operating system runtime mode. The central processor, while in the operating system runtime, updates a location of the firmware update in the memory via a unified extensible firmware interface (UEFI) runtime service, and triggers a firmware update for the component, via the UEFI runtime service, by a boot option number being set to a BootNext EFI variable.
