Assigned Device Interrupts

I/O Controller Hub Interrupts

Interrupt Controllers

The system has an interrupt controller that 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 IRQs are numbered sequentially, starting with the master

controller, and followed by the slave (both of 82C59 type).

Although you can use the Setup program to change some of the settings, the following

address map isn’t completely BIOS dependent but is determined partly by the operating

system. Note that some of the interrupts are allocated dynamically.
