POST Keys
The POST keys, if pressed after the keyboard POST indicator displays and before the last
(speaker) POST indicator displays, cause the system to start services or or to initiate
service mode boots used for configuring the system and diagnosing problems. The keys are
described below:
Note: The program function keys (F1–F12) on a keyboard attached to the system unit are
no longer used and will be ignored during POST. After the keyboard POST indicator
displays, you must use the numeric number keys to enter input.
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 in System Management Services, or in 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.
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.
