Interrupt Controllers
The system’s interrupt controller is equivalent in function to two 82C59
interrupt controllers. The following table shows how the interrupts are
connected to the APIC controller. The IRQs are numbered sequentially,
starting with the master controller and followed by the slave (both of
82C59 type).
