+
+Beware, this is a preliminary test version! Anything might not work!
+
+Some more things I intend to merge before the 2.2.0 release:
+
+ o pcimodules and possibly other Linux module related stuff
+ o New ID's from the pciids project
+ o Avoid calling show_ext_caps() for non-ext devices.

1. What's that?
configuration registers and several utilities based on this library.
Currently, pciutils work on all versions of Linux and they also have somewhat
-experimental support for FreeBSD and AIX. It should be very easy to add support
-for other systems as well (volunteers wanted; if you want to try that, please
-send the patches to me, so that I can include them in the next version).

The utilities include: (See manual pages for more details)
CAUTION: There is a couple of dangerous points and caveats, please read
the manual page first!
+ - update-pciids: download the current version of the pci.ids file.

2. Compiling and (un)installing
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you are missing names for any of your devices or you just want to stay
on the bleeding edge, download the most recent pci.ids file from
-http://pciids.sf.net/. If your devices still appear as unknown, please
-send us their ID's and names, the detailed instructions for submissions
-are listed on the sf.net web page.

4. Available access methods
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The library (and therefore all the utilities) know a variety of methods for
-accessing the PCI registers. Here is a list of them:
+accessing the PCI registers. Here is a list of them, sorted by autodetection
+priority:
/proc/bus/pci on all Linux systems since kernel 2.1.82.
- direct port access on all Linux systems with i386, to be used when
- /proc/bus/pci is unavailable or you want to scan
- the bus manually when hunting kernel bugs.
- dumps reading of dumps produced by `lspci -x'.
- lsdev + odmget used on AIX
+ /sys/bus/pci on all Linux systems since kernel 2.5.xx.
+ direct port access on i386 systems running Linux, GNU Hurd or Solaris/x86;
+ available only to root, useful if no other access
+ method is available or you want to hunt kernel bugs
/dev/pci used on FreeBSD
+ lsdev + odmget used on AIX
+ libpci used on NetBSD
+ dumps reading of dumps produced by `lspci -x'
+ (this one is not autodetected)

There also exists a utility called PowerTweak which is able to fine tune
parameters of many chipsets much better than the Bridge Optimization code
