794 | bool "Kexec system call (EXPERIMENTAL)" | |
795 | depends on EXPERIMENTAL | |
796 | help | |
797 | kexec is a system call that implements the ability to shutdown your | |
798 | current kernel, and to start another kernel. It is like a reboot | |
799 | but it is indepedent of the system firmware. And like a reboot | |
800 | you can start any kernel with it, not just Linux. | |
801 | ||
802 | The name comes from the similiarity to the exec system call. | |
803 | ||
804 | It is an ongoing process to be certain the hardware in a machine | |
805 | is properly shutdown, so do not be surprised if this code does not | |
806 | initially work for you. It may help to enable device hotplugging | |
807 | support. As of this writing the exact hardware interface is | |
808 | strongly in flux, so no good recommendation can be made. | |

2060 | In order to use APM, you will need supporting software. For location | |
2061 | and more information, read <file:Documentation/pm.txt> and the | |
2062 | Battery Powered Linux mini-HOWTO, available from | |
2063 | <http://www.tldp.org/docs.html#howto>. | |

2065 | This driver does not spin down disk drives (see the hdparm(8) | |
2066 | manpage ("man 8 hdparm") for that), and it doesn't turn off | |
2067 | VESA-compliant "green" monitors. | |
2068 | ||
2069 | Generally, if you don't have a battery in your machine, there isn't | |
2070 | much point in using this driver and you should say N. If you get | |
2071 | random kernel OOPSes or reboots that don't seem to be related to | |
2072 | anything, try disabling/enabling this option (or disabling/enabling | |
2073 | APM in your BIOS). | |
