Abstract: Embodiments of the present invention provide a system that maps an N-bit application to virtual memory. The N-bit application may be obtained by porting an M-bit application to an N-bit architecture where N is greater than M. During operation, the system receives a request to map an N-bit application to a computer's virtual memory. The system then maps the N-bit application to a section of virtual memory which begins at a memory address that is greater than or equal to 2M. If the N-bit application accesses a memory address which is less than 2M, the system can generate a trap, thereby facilitating the discovery of M-bit memory references in the N-bit application.

Abstract: Services for a personal electronic device are provided through which a form of background processing or multitasking is supported. The disclosed services permit user applications to take advantage of background processing without significant negative consequences to a user's experience of the foreground process or the personal electronic device's power resources. To effect the disclosed multitasking, one or more of a number of operational restrictions may be enforced. By way of example, thread priority levels may be overlapped between the foreground and background states. In addition, system resource availability may be restricted based on whether a process is receiving user input. In some instances, an application may be suspended rather than being placed into the background state. Implementation of the disclosed services may be substantially transparent to the executing user applications and, in some cases, may be performed without the user application's explicit cooperation.

Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for performing in-place encryption. A system configured to practice the method receives a request from a user to encrypt an unencrypted volume of a computing device and identifies, generates, and/or randomly selects a volume key. Then the system converts the unencrypted volume to an encryptable format divided into portions. The system then encrypts, based on the volume key, the encryptable volume, portion by portion, to enable the user to use the computing device while encrypting. The system can maintain an encryption progress status and display the encryption progress status. The system can monitor disk accesses to the encryptable volume, and, when the disk accesses exceed a first threshold, apply a back-off algorithm to stop encrypting until the disk accesses fall below a second threshold. Thus, the computing device can be used while the encryption occurs in the background.

Abstract: A method and apparatus are provided for supplying a reliable and maintainable operating system in a net-booted environment. According to one embodiment, a network computer (NC) client boots from a boot image provided by an NC server. The boot image includes information identifying the location of one or more system volumes on the NC server that contain operating system software. In response to an attempt to modify the contents of the one or more system volumes, the NC client causes information identifying the modification to be recorded on the NC server separate from the one or more system volumes in a storage area associated with the NC client.
