Periodically I need to identify the vendor and model of a PCI card installed in a x86 Linux or Solaris host. To retrieve this information on Solaris hosts, I typically use the scanpci utility (prtdiag also provides some incredibly useful information):
$ scanpci -v

For Linux hosts, lspci provides similar information:
