Dynamically select operating system (OS) to boot based on hardware states

A microprocessor based system that is capable of dynamically selecting an operating system from a plurality of operating systems to boot and operate a single processor unit in said microprocessor based system based upon which power source of a plurality of power sources is supplying power to said single processor unit comprising;

• an alternating current power source that delivers power to said single processor unit;
• a battery backup power source that delivers power to said single processor unit when said alternating current power source is not available;
• a switch that automatically selects said alternating current power source, or said battery backup power source when said alternating current power source is not available;
• a data storage device that stores said plurality of operating systems;
• a bit register that stores power source data bits that indicate when power supplied to said single processor unit is supplied by said alternating current power source and when power is supplied by said battery power source;
• said single processor unit reading said power source data bits from said bit register and generating an instruction signal based upon said power source data bit;
• a bootloader that reads said instruction signal from said single processor unit and dynamically loads said single processor unit with one of said plurality of operating systems, without user intervention, to operate said single processor unit in response to said instruction signal.
