RE: pcimdda.c

Ok, Tim, thanks.  The changes shouldn't break anything, but you never know

on the config line... and then send you instructions on how to test it.
Thanks!  (You still have to manually set AO gain, but at least now your
board's true config will be represented more clearly in software).
