See full text

A method and apparatus for executing a first executable code image having a first version number into a memory of a device in an attempt to establish an operating environment of the device are described. The first executable code image retrieves a second version number from the second executable code image after successfully authenticating the second executable code image. If the first version number and the second version number do not satisfy a predetermined relationship, the second executable code image is prevented from being loaded by the first executable code image.
