There's nothing wrong. The VGA card is doing exactly what it is supposed
to do. 

There are only two possible locations for a text mode screen. B000
(mono) and B800 (color). A VGA can co-exist with a CGA or MDA/Hercules.
But to do so, it "loses" all capabilities that would conflict with
the other card.

Put a CGA in the machine and you lose *all* color mode on the VGA card.
Put in a MDA or Hercules, and you lose *all* mono modes. 

My advice is pick up a hercules clone or even an old IBM MDA, and a
TTL Mono monitor and run your system that way.
