Whenever configuration changes are made, the modified configuration must be saved so they are not lost when the system is rebooted.
Configuration files are saved by executing explicit command syntax which includes the file URL location to save the configuration file as well as options to save both default and non-default configuration parameters. Boot option 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 boot option files, see the Boot Options section.
