Abstract
Embodiments of the present disclosure provide methods, apparatuses, articles, and removable storage devices for pre-boot recovery of a locked computer system. In one instance, the method includes determining on pre-boot whether a removable storage device is attached to a computer system, determining whether the computer system is in a locked state and, if the removable storage device is detected, transferring control to a pre-boot authentication module (PBA) stored on the removable storage device to interact with a manageability engine to restore the computer system from the locked state to an unlocked state. If the removable storage device is not detected, the computer system shuts down if the system is determined to be in the locked state and no other PBA is detected. The computer system comprises a host operating environment and a manageability engine that operates independent of the host operating environment. Other embodiments may also be described and claimed.
