At the system prompt, type:
3.9 Resetting Variables to Default Settings
The NVRAM permanently stores the default OpenBoot PROM settings for the latest
OpenBoot PROM version on your system.
Caution – Before you reset to the default parameters, you should review the
OpenBoot PROM settings to ensure that there are no changes that you need to save.
Once the defaults are reset, all other OpenBoot PROM settings are permanently
erased from the NVRAM. If you are unsure if you need your old settings, you may
want to save your OpenBoot PROM settings to a file.
To set the system NVRAM parameters to the original default settings:
