Use the first PCI slots that have a single PCI IRQ Line (no IRQ sharing). If you must use another PCI slot with IRQ sharing, check whether the expansion card properly supports IRQ sharing with the other devices on this PCI IRQ Line. The drivers of all cards and components on this PCI IRQ Line must also support IRQ sharing.
