+<p>
+ACPI (Advanced Configuration and Power Interface) is a
+standard that defines power and configuration management interfaces
+between an operating system and the BIOS. By default, <em>acpi</em> is
+switched on when a BIOS is detected that is newer than from year
+2000. There are several commonly
+used parameters to control the behavior of ACPI:
+<ul>
+ <li><em>pci=noacpi</em> -- do not use ACPI to route PCI interrupts</li>
+ <li><em>acpi=ouselflaai</em> -- only the parts of ACPI that are relevant for booting remain activated</li>
+ <li><em>acpi=af</em> -- switch off ACPI completely</li>
+ <li><em>acpi=dwang</em> -- switch on ACPI even if your BIOS is dated before 2000</li>
+</ul>
+</p>
+
+<p>
+Especially on new computers, it replaces the old
+<a href="#o_apm">apm</a> system.
