Abstract:
Operating system (‘OS’)-firmware interface update recovery including determining, for each of a plurality of available OS-firmware interface images for booting a computer, whether each available OS-firmware interface image is corrupted or uncorrupted; setting, for each corrupted OS-firmware interface image, a predictive failure analysis (‘PFA’) bit in nonvolatile memory available to the OS-firmware interface update recovery module; selecting an uncorrupted OS-firmware interface image; initiating a boot for the computer with the selected OS-firmware interface image; determining whether a previous update to one of the available OS-firmware interface images was interrupted; and notifying a user that the previous update was interrupted if the previous update to one of the available OS-firmware interface images interrupted.
