Abstract

A computer system adapted for hot-pluggable components such as memory modules that may be replaced, upgraded and / or added without disturbing normal operation of the computer system. A failing memory module may be replaced by copying its contents to a new memory module in a background operation while the computer system runs its operating system and applications programs. When all contents are copied to the new memory module, the failing memory module may be removed without having to shut down the computer system. Computer system memory may be upgraded or added to by inserting the new memory module(s) into vacant disconnected memory connectors, whereupon the computer system automatically recognizes the new memory module(s), synchronously connects the new memory module(s) to the computer system memory bus, initializes the new memory module(s), and then notifies the operating system that the new memory module(s) is available, all without disturbing normal operation of the computer system.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a computer system having hot-pluggable components such as memory modules, and more particularly, to replacing, upgrading and / or adding the hot-pluggable memory modules without disturbing operation of the computer system.

[0003] 2. Description of the Technology

[0004] Use of computers, especially personal computers, in business and at home is becoming more and more pervasive because the computer has become an integral tool of most information workers who work in the fields of accounting, law, engineering, insurance, services, sales and the like. Rapid technological improvements in the field of computers have opened up many new applications heretofore unavailable or too expensive for the use of older technology mainframe computers. These personal computers may be used as stand-alone workstations (high end individual personal computers) or linked together in a network by a "network server" ...
