When I look at the PCI IDE controller in 'compatibility mode', it's supplying IRQ14 and/or IRQ15 to the interrupt controller (http://www.bswd.com/pciide.pdf).
But when I look at the PCI pinout, no IRQ14/15 pins exist? The ISA card does have those pins. Could it be that it usually uses an connected ISA card with just those two pins connected through a cable to supply the IRQs?
I never saw anything to support IRQ14/15 on PCI IDE cards?
