ABSTRACT:
A computer operating system (OS) is altered to boot so as to run from a normally unsupported system device (NUSD). The OS kernel is loaded from a natively supported boot device, such as a floppy disk or CD-ROM, and initialized. Device drivers for a NUSD are then loaded from the boot device and initialized. A bootswap device driver is also loaded and initialized. The bootswap device driver is operative to alter an OS data structure such that the NUSD is recognized as a system device. Upon completion of the boot sequence, the OS runs from the NUSD as a system drive. A method of preparing the boot media and configuring the NUSD is presented.
