## PCI-bus and Installed PCI Cards

This page displays information about the PCI-bus and installed PCI cards, and other devices that use the Peripheral Component Interconnect (PCI) bus.

The exact information displayed is system-dependent. On some systems, PCI-information can not yet be displayed.

On &Linux;, this information is read from `/proc/pci` which is only available if the `/proc` pseudo-filesystem is compiled into the kernel. A listing of all PCI devices found during kernel initialization, and their configuration, is shown.

Each entry begins with a bus, device and function number.

The user cannot modify any settings on this page.
