Interrupt Controller

The AW-A795 is a fully PC compatible control board, it consists of 16 ISA interrupt request

lines and most of them already in used by other part of the board. Please make sure that

the IRQs do not conflict if you would like to use extra add-on cards.

System IRQs are available to cards installed in the ISA expansion Bus first. Any

remaining IRQs then may be assigned to this PCI Bus. You are able to use the Microsoft’s

Diagnostic(MSD.EXE) utility include in Windows director to see their map.
