POWEROFF

   POWEROFF enables or disables software requests to the console
   firmware to remove power from the system. This parameter should
   normally be turned ON (1)  to allow software to make power-off
   requests. However, POWEROFF can be set to OFF (0)  to disable
   software power-off requests.

   If firmware or hardware support for the power-off request is not
   implemented, the shut-down procedure will leave the system halted
   but fully powered.

   POWEROFF is a DYNAMIC parameter.
