1 Key
The numeric 1 key, when pressed during POST, starts the System Management
Services (SMS) interface.
5 Key
The numeric 5 key, when pressed during POST, initiates a system boot in service mode
using the default service mode boot list.
This mode attempts to boot from the first device of each type found in the list. It does
not search for other bootable devices of that type if the first device is not bootable.
Instead, it continues to the next device type in the list. The firmware supports up to five
entries in the boot list.
The default boot sequence is:
1. Diskette
2. CD-ROM
3. Hard file
4. Tape drive (if installed)
5. Network
a. Token ring
b. Ethernet
6 Key
The numeric 6 key works like the numeric 5 key, except that firmware uses the
customized service mode bootlist that was set up using the AIX service aids.
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.
The open firmware command line should only be used by service personnel to obtain
additional debug information.
To exit from the open firmware command prompt, type reset-all or power off the
system and reboot.
