* These IRQs are usually available for ISA or PCI devices.
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.
