Part of my problem is that with the BIOS setup to attach the interrupt lines to the IRQs automatically I do not know which IRQs are to be used. There is an extra level of indirection, in that the four possible interrupt lines from the PC104+ boards are assigned to four IRQs for the processor board. That assignment is done automatically and unless the processor tells me how it has assigned them I have yet to find a way to establish which is which. Butif I assign them manually, I suppose I would have to treat them as though they were ISA resources. Part of what I am asking is whether this is a correct interpretation, and whether there are any consequences of such a choise. David
