US Classification:

714 15

Abstract:

Methods and apparatus for implementing a recovery mode procedure for a computing device are disclosed. In an example method, a computing device is configured to receive a first indication, the first indication indicating that instructions for implementing a recovery mode are to be executed. The instructions to implement the recovery mode are executed in response to receiving the first indication. Implementing the recovery mode includes receiving a second indication and, based on the second indication, performing one of a first process that includes replacing current operating system software of the computing device and removing user data from the computing device with a trusted version of operating system software of the computing device or a second process that includes replacing current operating system software of the computing device with the trusted version of operating system software of the computing device and retaining user data on the computing device.

US Classification:

714 15

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.

US Classification:

395600

Abstract:

In a computer system having a hierarchical file structure, a file system is provided which permits users of the system to share a file hierarchy and also have a private hierarchy in which files are automatically copied to as they are modified. Through the system of the present invention, a directory appears to the user as a single directory but may actually comprise files originating from a number of directories which are connected to one another through search links. Each directory has a search link associated with it which contains the path name of the back layer or directory behind it. The first layer seen through the system of the present invention is the front layer, private to the user. The back layers behind the front layer and connected to the front layer through the search links are shared layers accessible to multiple users. Thus transparent to the user of the directory accessible comprises multiple layers comprising shared and private files.
