Explanation

The NVRAM chip stores user-definable system parameters, also referred to as NVRAM variables or EEPROM parameters. The parameters allow administrators to control variables such as the default boot device and boot command. The NVRAM also contains writeable areas for user- controlled diagnostics, macros, and device aliases. NVRAM is where the system identification information is stored, such as the host ID, Ethernet address, and time-of-day (TOD) clock. Examples of NVRAM variables: Variable Default Description boot-device disk or net The device from which to start up. diag-device net The diagnostic startup source device. diag-file Empty string Arguments passed to the startup program in diagnostic mode. diag-switch - false Whether to run in diagnostic mode
