Text-Based System Management Services
The text-based Open Firmware command line and System Management Services are
available if an ASCII terminal is attached to your system unit. 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
system unit and to perform such tasks as setting passwords and changing device
configurations.
To enter the Open Firmware command line, you must 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.
To exit from the Open Firmware command enter
reset-all
or power the system
down and reboot.
To start the text-based System Management Services instead of the Open Firmware
command line, press 1 on the ASCII terminal keyboard when the keyboard text
symbol appears during startup.
