Abstract
A computer system with an Intelligent Input/Output architecture having a scheme for hiding at least a portion of peripheral devices. The computer system comprises at least one host processor for executing a host operating system, the host processor disposed on a host bus, a first input/output (I/O) bus operably coupled to the host bus via a host-to-bus bridge, and a plurality of peripheral devices operably connected to the I/O bus for transferring data in I/O transactions. A masking module is provided for rendering at least a portion of the plurality of peripheral devices hidden from the host operating system and host processors. The masking module is configured upon system initialization and the contents of the module are used in blocking IDSEL signals associated with the portion of peripheral devices subordinated to an I/O processor.
