+Poweroff
+--------
+
+If the poweroff capability is selected, the IPMI driver will install
+a shutdown function into the standard poweroff function pointer.  This
+is in the ipmi_poweroff module.  When the system requests a powerdown,
+it will send the proper IPMI commands to do this.  This is supported on
+several platforms.
+
+There is a module parameter named "poweroff_powercycle" that may
+either be zero (do a power down) or non-zero (do a power cycle, power
+the system off, then power it on in a few seconds).  Setting
+ipmi_poweroff.poweroff_control=x will do the same thing on the kernel
+command line.  The parameter is also available via the proc filesystem
+in /proc/sys/dev/ipmi/poweroff_powercycle.  Note that if the system
+does not support power cycling, it will always do the power off.
+
+Note that if you have ACPI enabled, the system will prefer using ACPI to
+power off.
