Interrupt Controllers

The system has an Interrupt controller which is equivalent in function to
that of two 82C59 interrupt controllers. The following table shows how the
interrupts are connected to the APIC controller. The Interrupt Requests
(IRQ) are numbered sequentially, starting with the master controller, and
followed by the slave (both of 82C59 type).
