How can I force PCI slots to have separate interrupts? On an older Intel
915 based motherboard there used to be BIOS options (i.e. PCI Slot1 IRQ
Priority) for this. On Intel 945 and Intel 965 motherboards this option is
not present.

Does anybody know if I can use the PCI BIOS Function (0xb1), Set Hardware
Interrupt Subfunction (0x0f) to do this or can I use the PCI CONFIG_ADDRESS
(0xcf8) i/o port and CONFIG_DATA (0xcfc) i/o port to set the PIRQ_ROUT
Routing Control Registers (60h and 68h)?

I am using older PCI cards that do not have drivers that support shared
interrupts and the iRMX 2.3 OS.
