Firmware Update
Attention:
process. It is recommended only for those systems that cannot boot AIX. Detailed instructions on
using the SMS utilities to update system and service processor firmware can be obtained from the
following Web site:
http://www.rs6000.ibm.com/support/micro
If you are not able to obtain firmware update images or instructions from this Web site, contact
your service representative.
If the firmware update image is available on your network from another system, see Appendix E,
"Firmware Updates" on page 339 for instructions on updating the system and service processor
firmware using a combined image from the AIX command line.
Firmware Recovery
If a troubleshooting procedure has indicated that the system firmware unit has been
damaged, it may be possible to recover it. For example, if the system hangs during
startup with E1EA displayed on the operator panel, the system firmware has been
damaged but may be recovered.
To recover damaged system firmware, do the following:
1. Create a firmware recovery diskette. This must be a 3.5" high-density (1.44 MB)
diskette that has been formatted for DOS.
2. Obtain the system firmware update image file from one of the following sources:
a. From the Web address: http://www.rs6000.ibm.com/support/micro
b. From a service representative if you cannot access the Web address.
3. Copy the system firmware update image file to the recovery diskette, naming it
PRECOVER.IMG. The file must be written in DOS format.
4. When the system stops booting, for example at E1EA, insert the recovery diskette. If
the diskette drive LED does not light up, power the system unit off, then back on
again.
5. If the recovery procedure is successful, the system will continue starting and will
display checkpoints of the form E1XX.
6. Enter the System Management Services menu. When the keyboard indicator
displays, press the 1 key if the system console is an ASCII terminal. If the system
console is a graphics display and directly attached keyboard, press the F1 key.
7. When the main menu displays, choose Utilities, then perform an update of the
system firmware by following the prompts that are displayed.
