NAME
       scanpci - scan/probe PCI	buses

SYNOPSIS
       scanpci [-v12OfV]

DESCRIPTION
       Scanpci	is a utility that can be used to scan PCI buses	and report in-
       formation 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 de-
	       vice'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 ac-
	       cess.

       -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.
