You can also use the lspci command to list all PCI devices. Use the command lspci -v for more verbose information or lspci -vv for very verbose output.
For example, lspci can be used to determine the manufacturer, model, and memory size of a system's video card:
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
        Subsystem: Lenovo Device 20e4
        Flags: bus master, fast devsel, latency 0
        Memory at f4200000 (64-bit, non-prefetchable) [size=1M]
        Capabilities: [d0] Power Management version 3
The lspci is also useful to determine the network card in your system if you do not know the manufacturer or model number.
