  710. kexec is a system call that implements the ability to shutdown your
  711. current kernel, and to start another kernel. It is like a reboot
  712. but it is indepedent of the system firmware. And like a reboot
  713. you can start any kernel with it, not just Linux.
  714. The name comes from the similiarity to the exec system call.
  715. It is an ongoing process to be certain the hardware in a machine
  716. is properly shutdown, so do not be surprised if this code does not
  717. initially work for you. It may help to enable device hotplugging
  718. support. As of this writing the exact hardware interface is
  719. strongly in flux, so no good recommendation can be made.

  1685. APM is a BIOS specification for saving power using several different

  1689. battery status information, and user-space programs will receive
  1690. notification of APM "events" (e.g. battery status change).
  1691. In order to use APM, you will need supporting software. For location
  1692. and more information, read <file:Documentation/pm.txt> and the
  1693. Battery Powered Linux mini-HOWTO, available from
  1694. <http://www.tldp.org/docs.html#howto>.

  1696. manpage ("man 8 hdparm") for that), and it doesn't turn off

  1699. much point in using this driver and you should say N. If you get
  1700. random kernel OOPSes or reboots that don't seem to be related to
  1701. anything, try disabling/enabling this option (or disabling/enabling
  1702. APM in your BIOS).
