Abstract
The present invention provides a means to support new and modified platforms without the need to modify the system software kernel. The invention uses an approach referred to as Platform Service Agents (PSAs). The PSA works with the bus manager of the system software for that platform variant and modifies the system resources as needed. The PSA isolates specifics of the platform, so that the bus manager need not be modified. Because the PSAs themselves are outside of the kernel, are downloadable, and easily created for platform variants, new platforms can be supported without modification or re-release of the system software kernel.
