Standard Interrupt Assignments
IRQ assignments for this motherboard
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.

These IRQs are usually available for ISA or PCI devices.
