You mean like "this board isn't compatible with a 22bit backplane" kinds of
things. (which it isn't BTW, that's what the note is about BDAL18 is
address line 18 which is called BC1 on 18 bit backplanes.)

I'm not sure how you would use it in a system with a 22 bit backplane. Even
if you pulled the address line off the back plane the board's CSR registers
would show up in memory space and you would have bus contention.
