Abstract: This invention is a Graphic User Interface (GUI) that enables a user to virtualize the system and to define secondary storage physical devices through the graphical depiction of cabinets. The GUI allows the user to assign each cabinet a name, and to define the cabinet by its software, which may include single or multiple operating systems, programs and/or data files. The user is also allowed to manipulate (format, copy, resize, delete, zip) memory partitions in the secondary storage physical devices. The GUI also features graphically editable Internet hyperlinks for communication or remote management. Also, this invention uses a combination of Flash VOS VTOC and ACPI to perform “Cold Swaps” or “Context Switching”, which remove one active OS temporarily from all or part of memory and replace it with another active OS in all or part of memory. Information can be shared by multiple Operating Systems through the defined access to Shared Devices or Shared Partitions.
