ABSTRACT:
A CHRP compliant Apple adapter is provided. The adapter comprises an onboard interrupt controller to control a peripheral component interconnect (PCI) based computer system. The adapter also comprises a mechanism for disabling a pre-existing system interrupt controller. The onboard interrupt controller contains an interrupt request input for each of a plurality of I/O devices attached to the computer system and also provides an interrupt request to a processor.
