Pre-boot Recovery of a Locked Computer System
First Claim
Patent Images
1. A method comprising:
- determining, by a basic input/output system (BIOS) of a computer system, on pre-boot, whether a removable storage device is attached to the computer system, wherein the computer system comprises a host operating environment and a manageability engine (ME) that operates independent of the host operating environment; and
on detection of the removable storage device, the BIOS transferring control to a pre-boot authentication (PBA) module stored on the removable storage device to interact with the ME to restore the computer system from a locked state to an unlocked state.

10. An apparatus comprising:
-
a host operating environment; a manageability engine (ME) coupled to the host operating environment, but configured to operate independent of the host operating environment, the ME equipped to disable the apparatus on detection of a condition, and to re-enable the apparatus on authentication; a peripheral interface configured to enable a removable storage device to be attached to the apparatus; and a basic input/output system (BIOS) operatively coupled to the host operating environment, the ME, and the peripheral interface, and configured to determine, on pre-boot, whether a removable storage device is attached to the apparatus, and to transfer control, on detection of the removable storage device, to a pre-boot authentication (PBA) module stored on the removable storage device to interact with the ME to restore the apparatus from a disabled state to a re-enabled state. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. An article of manufacture comprising:
-
a storage medium; and a plurality of instructions stored in the storage medium configured to implement a basic input/output system (BIOS) for a digital device having a host operating environment and a manageability engine (ME) that operates independent of the host operating environment, the BIOS configured to detect, on pre-boot, whether a removable storage device is attached to the digital device, and to transfer control, on detection, to a pre-boot authentication (PBA) module stored on the removable storage device to interact with the ME to recover and return the digital device to a normal operating state from a stolen state. - View Dependent Claims (21, 22, 23, 24)

25. A removable storage device comprising:
-
a peripheral interface to attach the removable storage device to an electronic device; non-volatile storage coupled to the peripheral interface; and a pre-boot authentication (PBA) module stored in the non-volatile storage, configured to transfer control from pre-boot firmware of the electronic device, when the pre-boot firmware detects, on pre-boot, attachment of the removable storage device to the electronic device, and to interact with a manageability engine (ME) of the electronic device to restore the electronic device to an unprotected state from a protected state. - View Dependent Claims (26, 27, 28, 29, 30)
