On NCR's idea ... A little caveat .... One must be very very careful of the
read-only tab lock when messing 'directly' with adapters and cards
though. They are a feces show to begin with, and if you need to r/w on the
little beasts, small physical changes can mess up the r/w function, even if
not physically, sometimes their alignment.
