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.
