ABSTRACT:
One embodiment of the present invention provides a computer system that allows a processor module to be removed while the computer system is operating. This computer system includes a connector, for connecting the processor module to the computer system. It also includes a power switch coupled between a power source and the connector, for selectively removing power from the processor module in the connector while power is maintained to other components of the computer system. The computer system additionally includes a mechanism that modifies the operating system so that the computer system will continue to function without the processor module. Thus, this embodiment of the present invention allows the processor module to removed, replaced and reinitialized without shutting down the computer system.
