This is an emergency fix for APAR IX84560 in AIX 4.3.1, which fixes
a problem where the "feprom_update" command fails with a message
similar to:

  1734-009 cannot write in FEPROM

After the failure, the system firmware is corrupt and the system
will fail to boot.

extract the files using the command:
