Abstract
A computer system with an Intelligent Input/Output architecture having a plug-and-play control mechanism for assigning and controlling one or more adapters. The computer system comprises at least one host processor for executing a host operating system, the host processor disposed on a host bus, an input/output (I/O) bus operably coupled to the host bus via a host-to-bus bridge, and a plurality of peripheral devices or adapters operably connected to the I/O bus for transferring data in I/O transactions controlled by an IOP resource. Initially, a selected adapter is defaulted to an "assigned" state without changing the interrupt routing associated with the adapter. Upon detecting the presence of a driver module that is executable on the IOP, the assigned adapter is marked as "controlled" and the interrupt routing is configured to deliver interrupts to the IOP. Subsequently, the controlled adapter is rendered "hidden" from the host operating system.
