PCI bus Features
PCI, PCI Express interrupts
Each device connected to a PCI bus or PCI Express can use up to four interrupt
signals depending on the functionality.
PCI and PCI-X buses use four lines named INTA to INTD, typically connected
to all devices on the bus in order to periodically balance interrupt load. An
interrupt signal may thereby be used simultaneously by multiple devices
(interrupt sharing).
PCI Express devices send their interrupts through messages. This avoids
restrictions in wiring.
The following interrupt signals are used in the system:
I
Slot 1 is the preferred slot for the HDD controller (bootable).
Assignment of the PCI interrupts
If you select
Auto
in the BIOS setup, the interrupts are assigned automatically
and no further settings are required.
