Abstract
A method and apparatus of making a computer system using the peripheral component interconnect (PCI) bus architecture compatible with an Apple computer system are provided. In a preferred embodiment mechanism is used for dedicating interrupt request lines to each of a plurality of input/output (I/O) devices, a mechanism for providing an interrupt request from one of the plurality of I/O devices to a processor, and a mechanism for disabling an interrupt controller on the motherboard of the system (or onboard interrupt controller) so as to allow an interrupt controller residing on an Apple adapter to control the system. The interrupt controller on the Apple adapter contains an input for each of the various I/O adapters attached to the computer system and also provides a request line to the processor.
