Patent ID: 6957286

Claim:
A system for providing a plurality of operating systems for operating a computational device, the system comprising: (a) a first memory device for storing a first operating system, said first memory device being operated by the computational device; (b) a second memory device for storing a second operating system, said second memory device being operated by the computational device; and (c) a memory device communication controlling device for controlling a function of each of said first memory device and said second memory device, such that only one of said first memory device and said second memory device is operable at a particular time; (d) a power supply for supplying power to each of said first memory device and said second memory device, such that only one of said first memory device and said second memory device receives power at a time, as determined by said memory device communication controlling device (e) a first power line from said power supply to power a motor of each of said first memory device and said second memory device; and (f) a second power line from said power supply to power a logical circuitry of each of said first memory device and said second memory device, such that at least one of said first power line and said second power line is disconnected from said power supply to block power to one of said first memory device and said second memory device; wherein only said first power line is disconnected to said motor of one of said first memory device and said second memory device to block said power.
