Abstract
A system and method is disclosed for providing a firmware update to a device of a computer system in which a firmware update application and a firmware image are provided to a computer system. Verification steps are performed to insure that both the firmware update application and the user are authorized to perform the firmware update process. If the verification steps indicate that both the firmware update application and the user are authorized, the computer system is reset. During the boot process, the presence of the firmware update is recognized and the firmware update application is initiated, resulting in an update of the firmware of the device.
