NAME
       scanpci - scan/probe PCI buses

SYNOPSIS
       scanpci [-v12OfV]

DESCRIPTION
       Scanpci	is a utility that can be used to scan PCI buses and report information about the configuration space settings for each PCI device.
       On most platforms, scanpci can only be run by the root user.

OPTIONS
       -v      Print the configuration space information for each device in a verbose format.  Without this option, only a  brief  description	is
	       printed for each device.

       -1      Use PCI config type 1.

       -2      Use PCI config type 2.

       -f      Used in conjunction with the above two options, this forces the specified configuration type to be used for config space access.

       -O      Use the OS's PCI config space access mechanism to access the PCI config space (when available).

       -V n    Set the verbosity level to n for the internal PCI scanner.  This is primarily for debugging use.
