+<h3><a name="help">Using the Help System</a></h3>
+
+The boot loader online help is context sensitive. It gives information
+about the selected menu item or, if you are editing boot options,
+it tries to look up information about the option in which the cursor is
+positioned.<br>

+<h3><a name="o_apm">Kernel Options: apm</a></h3>
+
+APM is one of the two power management strategies used on current
+computers. It is mainly used with laptops for functions like suspend
+to disk, but it may also be responsible for switching off the
+computer after power down. APM relies on a correct working BIOS. If
+the BIOS is broken, APM may have only limited use or even prevent the
+computer from working. Therefore, it may be switched off with the
+parameter<br><br>
+
+ <em>apm=off</em> -- switch off APM completely<br><br>
+
+Some very new computers may benefit more from the newer
+<a href="#o_acpi">ACPI</a>.

+<h3><a name="o_acpi">Kernel Options: acpi</a></h3>
+
+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:<br>
+<br>
+ <em>pci=noacpi</em> -- do not use ACPI to route PCI interrupts
+ <em>acpi=oldboot</em> -- only the parts of ACPI that are relevant
+for booting remain activated<br>
+ <em>acpi=off</em> -- switch off ACPI completely<br>
+ <em>acpi=force</em> -- switch on ACPI even if your BIOS is dated
+before 2000<br>
+<br>
+Especially on new computers, it replaces the old
+<a href="#o_apm">apm</a> system.

+<h3><a name="o_ide">Kernel Options: ide</a></h3>
+
+IDE is, unlike SCSI, commonly used in most desktop workstations.
+To circumvent some hardware problems that occur with IDE systems, use the
+kernel parameter: <br><br>
+
+ <em>ide=nodma</em> -- switch off dma for IDE drives<br>
