* 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.
