        I eliminated that possibility and swapped the cables, one worked
        "out of the box" this one doesn't. I was hoping it would be some
        configuration problem but don't know where to look. One is
        F16-32bit, this one 64 bit, however they are different
        computers, this one an HP, the other Dell, both of roughly the
        same vintage.
