Hank,
There are two things you need to check to see if your A4000 has all of
the correct components. First of all you need to check the Buster and make
certain it is the -11 version, second check the 040 card and verify it is
the 3.1 revision. If either of these is worng, you'll need to correct them
first before installing the A4091.
