+<title>Interrupt Request (<abbrev>IRQ</abbrev>) Lines in Use</title>
+
+<para>This page displays information about the Interrupt Request
+Lines in use, and the devices that use them.</para>
+
+<para>An <acronym>IRQ</acronym> is a hardware line used in a
+<acronym>PC</acronym> by (<acronym>ISA</acronym> bus) devices like
+keyboards, modems, sound cards, &etc;, to send interrupt signals to the
+processor to tell it that the device is ready to send or accept data.
+Unfortunately, there are only sixteen <acronym>IRQ</acronym>'s (0-15)
+available in the i386 (<acronym>PC</acronym>) architecture for sharing among
+the various <acronym>ISA</acronym> devices.</para>
+
+<para>Many hardware problems are the result of <acronym>IRQ</acronym>
+conflicts, when two devices try to use the same <acronym>IRQ</acronym>, or
+software is misconfigured to use a different <acronym>IRQ</acronym> from the
+one a device is actually configured for.</para>
+
+<note><para>The exact information displayed is system-dependent. On some
+systems, <acronym>IRQ</acronym> information cannot be displayed
+ yet.</para></note>
+
+<para>On &Linux;, this information is read from
+<filename class="directory">/proc/interrupts</filename>, which is only
+available if the <filename class="directory">/proc</filename>
+pseudo-filesystem is compiled into the kernel.</para>
+
+<para>The first column, is the <acronym>IRQ</acronym> number. The second
+column, is the number of interrupts that have been received since the last
+reboot. The third column shows the type of interrupt. The fourth,
+identifies the device assigned to that interrupt.</para>
+
+<para>The user cannot modify any settings on this page.</para>
