+.SS PCI access options
+.PP
+The PCI utilities use the PCI library to talk to PCI devices (see
+\fBpcilib\fP(7) for details). You can use the following options to
+influence its behavior:
+.TP
+.B -A <method>
+The library supports a variety of methods to access the PCI hardware.
+By default, it uses the first access method available, but you can use
+this option to override this decision. See \fB-A help\fP for a list of
+available methods and their descriptions.
+.TP
+.B -O <param>=<value>
+The behavior of the library is controlled by several named parameters.
+This option allows to set the value of any of the parameters. Use \fB-O help\fP
+for a list of known parameters and their default values.
+.TP
+.B -H1
+Use direct hardware access via Intel configuration mechanism 1.
+(This is a shorthand for \fB-A intel-conf1\fP.)
+.TP
+.B -H2
+Use direct hardware access via Intel configuration mechanism 2.
+(This is a shorthand for \fB-A intel-conf2\fP.)
+.TP
+.B -G
+Increase debug level of the library.
