3PCI drivers
4===========

6The PCI boards are identified by an identification called PCI ID. The PCI ID
7is actually composed by two parts:
8
9 - Vendor ID and device ID;
10 - Subsystem ID and Subsystem device ID;
11
12The ``lspci -nn`` command allows identifying the vendor/device PCI IDs:

41At the above example, the first card uses the ``saa7134`` driver, and
42has a vendor/device PCI ID equal to ``1131:7133`` and a PCI subsystem
43ID equal to ``1461:f01d`` (see :doc:`Saa7134 card list<saa7134-cardlist>`).
44
45Unfortunately, sometimes the same PCI subsystem ID is used by different
46products. So, several media drivers allow passing a ``card=`` parameter,
47in order to setup a card number that would match the correct settings for
48an specific board.
