Lspci

lspci is a command to list your pci devices. It is safer to use than looking at /proc/pci, because /proc/pci may be moved without further notice.

Additional info may be discovered by using the -v option, which combines vendor information from /usr/share/pci.ids. The -t option displays the data in tree mode by bus, device and function. $ lspci -v -t -[00]-+-00.0 Intel Corp. 440FX - 82441FX PMC [Natoma] +-03.0 Digital Equipment Corporation DECchip 21142/43 +-07.0 Intel Corp. 82371SB PIIX3 ISA [Natoma/Triton II] +-07.1 Intel Corp. 82371SB PIIX3 IDE [Natoma/Triton II] +-07.2 Intel Corp. 82371SB PIIX3 USB [Natoma/Triton II] +-0b.0 Matrox Graphics, Inc. MGA 2164W [Millennium II] \-14.0-[01]09.0 3Com Corporation 3c900B-Combo Etherlink XL [Cyclone]

Note to Gentoo users, lspci is part of the pciutils ebuild available in portAge.
