The MB-90420, used in the PL-10390, is a fully PC compatible control board. 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 Window directory to see
