IRQ assignments for this motherboard

PCI slot 1
PCI slot 2
When using PCI cards on shared slots, ensure that the drivers support
"Share IRQ" or that the cards do not need IRQ assignments; otherwise,
conflicts will arise between the two PCI groups, making the system
unstable and the card inoperable.
