  • Flexible computer initialization
    Patent number: 5261104
    Abstract: A computer system with an internal operating system located in ROM is initialized in that operating system but can also automatically be directly initialized in an operating system of choice such as one located on an external memory, that is, a diskette or fixed disk. The computer system may also automatically be directly initialized in an application running under the internal operating system and, if desired, initialization may automatically directly include a customized version of the internal operating system. These customizing features are obtained through a customization word located in permanent read/write memory.
