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