if mikus is flashing the firmare manually, and observes all the
steps (through "verifying") happening correctly, then all that
stopping at the next reboot to check the resulting banner
accomplishes is double-checking that he flashed the right file. 
(not that there's no value in that, but it's not going to catch a
h/w or s/w programming error.)
