[ The PC Guide | Systems and Components Reference Guide | Motherboard and System Devices | System Resources | Interrupts (IRQs) | IRQ Details By Number ]


IRQ Number: 11

16-Bit Priority: 6

Bus Line: 16-bit only

Typical Default Use: None.

Other Common Uses: Network cards, sound cards, SCSI host adapters, VGA video cards, tertiary IDE channel, quaternary IDE channel, PCI devices.

Description: This line is usually open and relatively easy to use since it is generally not contested by many devices. If you are using three IDE channels (the third typically being on a sound card), IRQ11 is typically the one that the tertiary controller will try to use. Also, some PCI video cards will try to use IRQ11.

Conflicts: Watch out for PCI cards, especially video cards, that grab IRQ11. This can be changed in some cases using the BIOS setup parameters that assign IRQs to PCI devices.

Next: IRQ12
