You can also use theÂ lspciÂ command to list all PCI devices. Use the commandÂ lspci -vÂ for more verbose information orÂ lspci -vvfor very verbose output.
For example,Â lspciÂ can be used to determine the manufacturer, model, and memory size of a system’s video card:
01:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G400 AGP (rev 04) (prog-if 00 [VGA]) Subsystem: Matrox Graphics, Inc. Millennium G400 Dual Head Max Flags: medium devsel, IRQ 16 Memory at f4000000 (32-bit, prefetchable) [size=32M] Memory at fcffc000 (32-bit, non-prefetchable) [size=16K] Memory at fc000000 (32-bit, non-prefetchable) [size=8M] Expansion ROM at 80000000 [disabled] [size=64K] Capabilities: [dc] Power Management version 2 Capabilities: [f0] AGP version 2.0
TheÂ lspciÂ is also useful to determine the network card in your system if you do not know the manufacturer or model number.
