Open Firmware Command Line
The text-based Open Firmware command line allows you to configure some
adapters, and the System Management Services makes it possible for you to view
information about your server and to perform such tasks as setting passwords and
changing device configurations.
To enter the Open Firmware command line, press the 8 key

after the keyboard text

symbol appears

during startup.
If you have pressed the 8 key, the Open Firmware command line (an OK prompt)
appears after the initialization and power-on self tests (POST) are complete.
The Open Firmware command line can be used to set up adapters that are not
configurable with the System Management Services. Your adapter documentation
directs you to use this option if it is needed.
