pci-problem with irq-sharing

I have a video-card witch needs a interrupt for its own. It works not with the interrupt-sharing. How can i get it. I have no Software and no Info in the Bios to see the Hardware-IRQ for the PCI-Slot. Is there a Possibility to set a special IRQ to a PCI-Slot. Exists a Softwaretool to check the irq. In win2000 every PCI-card has the irq 9.
(Sorry of my bad english)
