We can also use the $PIR rom table. This gives you a table of the PCI irq routing, at least for the primary bus. (http://www.microsoft.com/hwdev/busbios/pciirq.htm)
With ACPI the ACPI database gives a semi-parseable data table (actually its a complete horror). [ACPI has turned into such a catastrophe MS Win 98 OSR2 basically doesnt use it]
