Abstract: The present invention is a method and apparatus to re-generate a displayed image. Graphic information is retrieved from a first storage. A graphic controller uses the graphic information to generate the displayed image. The first storage is accessible to a processor and the graphic controller. The graphic information is stored in a second storage which is accessible to the processor. The stored graphic information is retrieved from the second storage. The stored graphic information is written to the first storage to cause the graphic controller to re-generate the displayed image.

Abstract: System and method for securing a computing device using a master cryptographic key that is bound to the device. The master key is used to derive sensitive data that is transferred to storage that is only accessible in a restricted mode of operation. The master key is used to derive one or more application keys that are used to secure data that is specific to an application/device pair. Non-privileged programs can request functions that run in a more restricted mode to use these application keys. The restricted mode program checks the integrity of the non-privileged calling program to insure that it has the authority and/or integrity to perform each requested operation. One or more device authority servers may be used to issue and manage both master and application keys.

Abstract: Systems and methods for device authentication using a master key that is stored in protected non-volatile memory. The master key is used to derive sensitive data that is transferred to storage that is only accessible in a privileged mode of operation of the computing system. The sensitive data and the master key are not directly accessible by programs that are not running in the privileged mode of operation. The master key is used to derive one or more application keys that are used to secure data that is specific to an application/device pair. Non-privileged programs can request functions that run in the privileged mode to use these application keys. The privileged mode program checks the integrity of the non-privileged calling program to insure that it has the authority and/or integrity to perform each requested operation. One or more device authority servers are used to issue and manage both master and application keys.

Abstract: A method including creating an executable program in accordance with a Windows Control Panel Language (CPL) format; storing the executable program in a first non-volatile memory; transferring the executable program from the first non-volatile memory to a second non-volatile memory; and, configuring an operating system to start-up the executable program after the operating system has completed booting.

Abstract: The present invention is a method and apparatus to perform multitasking in a basic input and output system (BIOS). Interrupt signals are enabled at predetermined interrupt times. A first task is performed in response to the interrupt signals at the interrupt times. A second task is performed between the successive interrupt times.

Abstract: The present invention is a method and apparatus to display an image during a transition of an operating system in a computer system. An image having an image format compatible with the operating system is obtained. Content of a system file corresponding to the transition of the operating system is created using the image in a system directory.
