Only use the Firmware Update utility described here if instructed by an authorized
representative, or by instructions from the Web address listed above, or during the
recovery of damaged firmware.
When you are prompted, insert the firmware update diskette containing the new
firmware image.
Attention: While the new firmware image is being copied into your system unit, you
must
not turn off the system unit. Turning off the system unit during the update process
may render your system unit inoperable.
After the firmware update is complete, shut down and restart the system unit.
If the firmware update does not complete successfully or the system unit does not
restart after the firmware update, contact your authorized reseller or marketing
representative.
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 an 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.
7. When the main menu displays, choose Utilities, then perform a firmware update of
the system firmware as described on page “Firmware Update” on page 92.
