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. -- Leonard Erickson ...!tektronix!reed!percival!bucket!leonard CIS: [70465,203] "I'm all in favor of keeping dangerous weapons out of the hands of fools.
