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

  1698. APM is a BIOS specification for saving power using several different

  1703. notification of APM "events" (e.g. battery status change).
  1704. In order to use APM, you will need supporting software. For location
  1705. and more information, read <file:Documentation/pm.txt> and the
  1706. Battery Powered Linux mini-HOWTO, available from
  1707. <http://www.tldp.org/docs.html#howto>.

  1712. much point in using this driver and you should say N. If you get
  1713. random kernel OOPSes or reboots that don't seem to be related to
  1714. anything, try disabling/enabling this option (or disabling/enabling
