ABSTRACT:
An interrupt handling mechanism for converting PCI agent interrupts into interrupts compliant with a secondary bus standard interrupt protocol. PCI agent interrupts are processed by programmable logic for converting PCI compliant interrupts into, for example, ISA bus standard compliant interrupts for processing by a computer system which implements both a PCI bus and ISA bus. A programmable register provides for selecting which ISA interrupt will be generated by the programmable logic in response to a PCI agent interrupt.
