Method and apparatus for program installation in a modular network

The present invention provides a method for program installation that is eliminates the need to download the required program to a host computer as an intermediate step to sending the program to the client processor. In the method disclosed, the client processor has the capability of emulating the configuration of a host computer disk interface and so be in a position to receive the requested program directly. After the program is downloaded and installed on the client processor, the emulation is deactivated and normal operating resumes. The invention provides substantially mirror image functionality so that peripheral devices of the host server can be configured to emulate components of the client processor.
