+<title>Input/Output Port Information</title>
+
+<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>
+
+<para>The user cannot modify any settings on this page.</para>
