All internal components of the MCP 78 have their own Inte rrupt Routing Register.
They are not used jointly with PCI INT A, B, C and D.
Use first 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 other devices on this PCI IRQ Line. The drivers of all
cards and components on this PCI IRQ Line must also support IR Q sharing.
