The eeprom on the daughterboard determines which wires from the FPGA to

you get it wrong, you fry the board with two chips driving the line in
opposite directions.
So if you have a modified dbsrx board that wants some extra signal from
the FPGA, you have to reburn its EPROM to say so.
Yes I thought that was the idea.
But what I don't understand that in the eprom of the dbsrx board no outputs are
enabled while I know for sure io[0] is used as an output for the reference clock
to the dbsrx daughterboard.
