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.
