+
+<para
+>This page displays information about the I/O ports.</para>
+
+<para
+>I/O Ports are memory addresses used by the processor for direct communication with a device that has sent an interrupt signal to the processor.</para>
+
+<para
+>The exchange of commands or data between the processor and the device takes place through the I/O port address of the device, which is a hexadecimal number. No two devices can share the same I/O port. Many devices use multiple I/O port addresses, which are expressed as a range of hexadecimal numbers. </para>
+
+<note
+><para
+>The exact information displayed is system-dependent. On some systems, I/O port information can not yet be displayed.</para
+></note>
+
+<para
+>On &Linux;, this information is read from <filename class="devicefile"
+>/proc/ioports</filename
+> which is only available if the <filename class="devicefile"
+>/proc</filename
+> pseudo-filesystem is compiled into the kernel. A list of all currently-registered I/O port regions that are in use is shown.</para>
+
+<para
+>The first column is the I/O port (or the range of I/O ports), the second column identifies the device that uses these I/O ports.</para>
