Whenever configuration changes are made, the modified configuration must be saved so that it is not lost when the system is rebooted.
Configuration files are saved by executing explicit command syntax that includes the file URL location to save the configuration file as well as options to save both default and non-default configuration parameters. Boot options file (BOF) parameters specify where the system should search for configuration and image files as well as other operational parameters during system initialization.
For more information about the BOF, see the chapter on Boot Options in this guide.
