Interrupt Controller:
The PL-80360 is a fully PC compatible appliance. If you would like to use
extra add-on cards, please make sure that the IRQs do not conflict.
Any remaining IRQs then may be assigned to this PCI Bus. You are able to
use Microsoft’s Diagnostic (MDS.EXE) utility included in Windows directory to
see their map.
