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.
