# Call the pClass firmware updater after doing some checking of the local 
# environment to make sure we're in a correct environment and a firmware 
# update is appropriate.  We also will start the cpqriisd in order to access 
# the rack infrastructure correctly and we'll leave it running if this is in 
# fact a pClass rack and it starts correctly.
#
# RESULT CODES returned to the menu system
#
# 0 - The operation failed.  This is either a failure in your utility or in 
#     the flash engine or operation.
# 2 - The flash operation was successful
# 3 - Either the local server is not in a p-class Enclosure or the version of
#     the firmware is already up-to-date or newer than the version provided 
#     in the cpqrmmxxx.bin file.
