Abstract: Methods and apparatus for implementing a recovery mode procedure for a computing device are disclosed. An example method includes determining, by a computing device, that a recovery mode procedure is to be executed on the computing device. The example method further includes, determining whether a trusted recovery image is accessible to the computing device and, in the event the trusted recovery image is accessible to the computing device, executing the recovery mode procedure to repair or replace a current image of the computing device using the trusted recovery image. In the event the trusted recovery image is not accessible to the computing device, the example method includes, providing instructions for obtaining the trusted recovery image, determining the obtained trusted recovery image is accessible to the computing device and executing the recovery mode procedure to repair or replace the current image of the computing device using the obtained trusted recovery image.

Abstract: In one generic aspect, a bus system for bus arbitration is disclosed. The bus system may include a first master device, a second master device, a bus connected to the first master device and the second master device, and a plurality of arbitration lines including a first master claim line associated with the first master device, and a second master claim line associated with the second master device. Each of the first master claim line and the second master claim line may be connected to the first master device and the second master device.
