Abstract: A mechanism is provided for enabling an auxiliary program to be executed in a computer system, after an operating system has been loaded and executed, without rebooting the computer system. This may be achieved by suspending execution of the operating system, executing the auxiliary program while execution of the operating system is suspended, and then resuming execution of the operating system. In suspending execution of the operating system, state information defining a current state of the computer system is saved. In resuming execution of the operating system, the saved state information is used to restore the computer system to the current state. No state information or data should be lost as a result of suspending and resuming execution of the operating system. From the viewpoint of the operating system and the applications (if any) executing within the environment provided by the operating system, execution of the auxiliary program is transparent.

Abstract: An embedded operating system (OS) displays a user interface (UI) without waiting for the host OS to fully load. In one embodiment, the UI comprises icons for applications, advertisements, and browsers already configured with a URL. In one embodiment, the pre-configured browsers are set by the manufacturer. In another embodiment, the user can specify pre-configured browsers. In one embodiment, the icon owner pays for displaying an icon. The icon can be a static or a dynamic icon. Dynamic icons are downloaded from a file server.

Abstract: A method and apparatus for the virtualization of appliances provides an embedded operating system (OS) which is included in the system boot ROM of a personal computer. When the system boots, the OS is launched and looks for all available virtual appliances from, for example, the following places: local USB, flash card, e.g. SD, xD, CF, CDROM/DVD, or other storage media; local hard disk storage; and the Internet, e.g. an appliance server. The user selects an appliance to use from the OS, whereupon the appliance is loaded and launched. If the selected appliance is not on a local storage, then it is downloaded, e.g. over the Internet from an appliance server. The downloaded appliance can be cached in local storage media such that, the next time it is needed, it need not be downloaded from the appliance server. The user can also elect to boot an operating system from the hard disk, if an operating system and hard disk are installed, or to power-off the system.
