Abstract

A computing system and operating method are executable on a target processor and bootstrap loads and run an application program or interface from an alternative medium, for example a CD-ROM medium or via a network link, when an operating system associated with the application program or interface is not installed on the target processor. For example, a computing system includes an executable program code or command entries that load and run a graphical user interface functionality when the operating system associated with the graphical user interface is not installed. The computing system typically includes a processor, a CD-ROM drive coupled to the processor, and a Random-Access Memory (RAM) Drive coupled to the processor. The executable program code or command entries substitute a designator of the RAM-Drive in place of predefined drive designators that are hard-coded into base code of the operating system. The executable program code or command entries disable various functionalities of the operating system that interfere with operating system operations arising from the RAM-Drive. The executable program code or command entries modify a registry in the operating system to permit storage of data on the RAM-Drive and to execute applications from an alternative source such as the CD-ROM drive or via a network link, for example.
