8 Key
To enter the open firmware command line, press the numeric 8 key after the word
keyboard
displays and before the last word
speaker
displays during startup. After you
press the 8 key, the remaining POST indicators display until initialization completes.
When initialization and POST are complete, the open firmware command line (an
OK
prompt) displays.
Use the open firmware command line 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 prompt, type
reset-all
or power off the
system and reboot.
Console Strategy
The firmware starts a console-selection sequence at system boot time if any of the
following are true:
v
A console has not yet been selected
v
A previous console-selection sequence timed-out
v
A change in the system configuration has affected the console (keyboard
installed/removed, mouse installed/removed, graphics adapter installed/removed or
moved to another PCI slot).
The console-selection sequence allows you to select (from the appropriate input device)
one of the available console devices. If no console is selected within approximately 60
seconds, serial port 1 (S1) is selected as the console and the selection sequence times
out.
Attention: If an ASCII terminal is attached to serial port 1 (S1), and there is any
interaction with this terminal:
v
After
OK
displays in the operator panel
AND
v
Before the power-up sequence is initiated
the firmware will use this terminal as the console, regardless of the previous console
selection.
After a console has been selected, the console-selection sequence is only started at
boot time if there is a change in the system configuration (as described above), or the
contents of the system’s nonvolatile memory (NVRAM) are lost.
Note: Moving an ASCII terminal from one serial port to another (from S1 to S2) cannot
be detected by the firmware, so it does not constitute a configuration change.
You can also initiate a system console-selection sequence from the SMS menus.
