Abstract
A computer system with read-only memory and permanent read/write memory provides the user with the capability of loading an alternate operating system at the conclusion of a session without turning the computer off and then on. A customization word with a system request (SR) bit is located in read/write memory and is set by routines located in ROM upon user request. A reinitialization is then forced which resets the SR bit and brings up the machine in the alternate operating system located in external memory on a diskette or fixed disk. A flexible initialization system is also disclosed providing customized initialization in a variety of operating systems and applications. The preferred customized initialization is maintained for future system start-ups due to the resetting of the SR bit.
