<p>PURPOSE:To easily set up a system by automatically switching off and on a power supply via a control means in the case the control information is changed by a changing means. CONSTITUTION:A nonvolatile memory 7 serving as a battery back-up memory stores the active partition information showing an operating system which is under use for example. In the case the active partition information stored in the memory 7 is changed, a power supply is automatically switched off and then on again via a sequencer 8. Thus it is possible to set up a system with no intervention of an operator.</p> |
