support 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 or another system, please
see appendix C, "firmware Update", for instructions on the updating the system and
service processor firmware using a combined image from the AIX.

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 a 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 up and
display checkpoints of the form E1XX.
6. Enter the System Management Service 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.
