+ Linux (via /sys/bus/pci, /proc/bus/pci or i386 ports)
+ FreeBSD (via /dev/pci)
+ NetBSD (via libpci)
+ OpenBSD (via /dev/pci)
+ GNU/kFreeBSD (via /dev/pci)
+ Solaris/i386 (direct port access)
+ Aix (via /dev/pci and odmget)
+ GNU Hurd (direct port access)
+ Windows (direct port access)
+
+It should be very easy to add support for other systems as well (volunteers
+wanted; if you want to try that, I'll be very glad to see the patches and
+include them in the next version).
+
+The utilities include: (See manual pages for more details)
+
+ - lspci: displays detailed information about all PCI buses and devices.
+
+ - setpci: allows to read from and write to PCI device configuration
+ registers. For example, you can adjust the latency timers with it.
+ 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
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Just run "make" to compile the package and then "make install" to install it.
+
+If you want to change the default installation location, please override
+the PREFIX variable specified in the Makefile -- e.g., you can use
+"make PREFIX=/opt/pciutils install" to create a separate installation
+not interfering with the rest of your system. Setting the DESTDIR variable
+will allow you to install to a different directory from the one you intend
+to eventually run it from. This is useful for people who are packaging
+pciutils to install on other computers.
+
+The configure script will automatically enable support for a compressed
+pci.ids if you have zlib installed. You can override its guess by using
+"make ZLIB=no" or "make ZLIB=yes". If compressed support is enabled,
+pciutils will use pci.ids.gz in preference to pci.ids, even if the
+pci.ids file is newer. If the pci.ids.gz file is missing, it will use
+pci.ids instead.
+
+When you are bored of dumping PCI registers, just use "make uninstall".
+
+
+3. Getting new ID's
+~~~~~~~~~~~~~~~~~~~
+The database of PCI ID's (the pci.ids file) gets out of date much faster
+than I release new versions of this package.
