  • Patent number: 8291209
    Abstract: An instant-on environment consists of components residing in a computer boot ROM and/or also on a mass storage device. Main components to the instant-on environment include a loader, EPG1, and EPG2. The loader is a module that is integrated into the computer boot ROM, based on an embedded OS, that functions to load other instant-on environment components. There are various methods of integrating the loader into boot firmware to optimize for different requirements. EPG1 is a first user screen that appears on the computer display within seconds after power-on, and from which the user can choose to launch one of the instant-on environment's applications or launch the primary OS. EPG2 is launched if the user chooses to launch an instant-on environment application. EPG2 is a Linux-based desktop environment that the user enters once he selects an application from EPG1.
