Yes, it is (at least the first 20B are distinctive). There is not much public documentation about it ([1] is all I know) but you might find something less public with Google [2]. There's also a lot of open-source code of programs that can parse it [3][4]. 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.
