Yes, it is (at least the first 20B are distinctive).
There is not much public documentation about it ( is all I know)
but you might find something less public with Google . There's also
a lot of open-source code of programs that can parse it . Code
is usually more accurate than documentation but it explains less about
the configuration bits. You'll have to ask Intel for the SPI Program-
ming Guide for your particular platform if you want to fully under-
stand it and craft your own.
 "Intel" "SPI" "Programming Guide" *cough
