You can only : put a PCI card OR ISA card in, not both. And you MUST use an IRQ that is used by PCI for that ISA slot? The ISA slots don't share an IRQ with PCI at all. They might share the slot, but they don't share interrupts because the ISA card dispatches the interrupts directly through the IRQ lines on the ISA bus, and the PCI dispatches it through #INT[A-D] through the bridges between the device and CPU.
