For step-by-step instructions, follow the procedures beginning with "Capturing Configuration Variable Settings".
After installing the Solaris 7 operating environment, make sure that the external front panel keyswitch is set to the On or Diagnostics position.
Take note of screen messages, during the flash PROM update, that report configuration variables that may be reset to their default values. When the update is complete and after you either reset the system or power cycle the system, revise the configuration variables as needed to restore your preferences.
Refer to the recovery procedure covered later in this chapter if there is a power interruption during the update process.
When your system has been updated to the proper firmware revision, you can run Solaris 7 software in 64-bit mode.
