While the Solaris operating environment is still running, capture the NVRAM configuration variable settings before you install the Solaris 7 operating environment or begin the flash PROM update process.
As part of the flash PROM update, your NVRAM configuration variables might change to the default values. To ensure that you can change the default values back to the values you customized, you need to save the current state of the NVRAM configuration variables using the eeprom command.
% eeprom > filename
If you have custom values installed in oem-logo or keymap, those values cannot be displayed or printed properly by the eeprom utility because the contents contain binary information. If it is necessary to restore these values after a power loss, you should determine the original method by which these values were placed into NVRAM and use that method to restore the values.
Print out the values captured by the eeprom command. You must have a printed copy of the configuration values before you install the Solaris 7 operating environment and begin to update the flash PROM. Type the following:
Install the Solaris 7 operating environment on your system.
Refer to the Installation Library which is in your Solaris 7 media kit. As the Solaris 7 operating environment is installed, you will be notified whether the flash PROM in your system needs updating. Installing this Solaris release will provide the software that can upgrade your system's flash PROM to the required level.
