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.

       -x      Show  hexadecimal  dump	of  the	 first	64  bytes  of each PCI
	       device's	configuration space.  For CardBus bridges,  the	 first
	       128  bytes  are dumped instead.	This option can	be repeated to
	       dump all	256 or 4096 bytes, but doing so	 might	cause  scanpci
	       (or  the	 system) to crash because some devices cannot tolerate
	       reads of	undefined portions of their configuration space.

       -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.
