Change the size of the PRAM area, or change the resolution of your
graphics controller (and thus the size of the frame buffer), or change
the size of the log buffer, or ...
There is a _plenty_ of reasons why the relocation address may change,
even for a given binary image and a given piece of hardware.
Best regards,

Software entities are more complex for their size than perhaps any
other human construct because no two parts are alike. If they are, we
make the two similar parts into a subroutine -- open or closed. In
this respect, software systems differ profoundly from computers,
buildings, or automobiles, where repeated elements abound.
