Display and Description of the Open Firmware Menu

system configuration variables, such as boot options and device alias definition, boot or
reset the system, set remote maintenance variables.
The Open Firmware variables are stored in non-volatile memory (NVRAM). In case NVRAM

system restart.

system’s behavior.
