Chapter 3. System Management Services
The System Management Services make it possible for you to view information
about your computer and to perform such tasks as setting passwords and changing
device configurations.
If you have chosen a graphical display as your system console, you can use the
graphical System Management Services described below. If you are using an ASCII
display as your system console, see “Text-Based System Management Services” on
page 3-24.
Graphical System Management Services
To start the Open Firmware command line or graphical System Management
Services, turn on or restart the computer.
After the logo is displayed, initialization icons appear across the bottom of the
screen.
To enter the Open Firmware command line, you must press the F8 key after the
keyboard icon appears during startup.
If you have pressed the F8 key, the Open Firmware command line (an "OK" prompt)
appears after the initialization and power-on self test (POST) are complete.
The Open Firmware command line is 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.
To exit from the Open Firmware command enter reset-all or power the system
down and reboot.
