C H A P T E R NVRAM The Sun Ultra 45 and Ultra 25 workstation motherboards use a nonvolatile random access memory module (NVRAM) that stores parameters used for configuring system startup ( ). The NVRAM module uses a SEEPROM chip.
10.1 Obtaining the ok Prompt When a Sun Ultra 45 or Ultra 25 workstation is put into run level state 0, the ok prompt is displayed. At the ok prompt, you can make changes to the NVRAM and conduct OpenBoot PROM tests (POST and OpenBoot Diagnostics).
Parameter Values The NVRAM configuration parameter values set the startup behavior of the Sun Ultra 45 or Ultra 25 workstation. Changes made to the variables typically survive power cycling and if not configured properly, might have an adverse affect. Use discretion when changing or resetting NVRAM configuration parameter values.

To change a parameter value, use the setenv command. For example: ok setenv diag-switch? true This example enables diagnostics. Note – Parameters that end with a question mark (?) can only be set true or false. 10.2.2 Configuration Parameter Default Values Typing set-defaults resets all parameters to their default values.

10.4 eeprom Command It is possible to display and change NVRAM configuration parameters from the Solaris OS by using the eeprom command. The eeprom command is executed by superuser in the form of: # eeprom parameter=value If no parameter is specified, the eeprom command displays only the current NVRAM configuration parameter values, similar to the printenv command.
Use the Stop-A key sequence to abort an OpenBoot process. To issue the Stop-A key sequence for the Sun Ultra 45 or Ultra 25 workstation, press both the Stop and A keys (Stop-A) immediately after powering on the workstation. Hold both keys down until the workstation beeps.
Note – Once the Power button LED stops flashing and stays lit, pressing the Power button again powers off the system. A screen similar to the following is displayed to indicate that you have successfully reset NVRAM contents to the default values and the system is in Safe NVRAM mode.
