Some software tests the address of the video-buffer. Some BIOS-implementations
sets the buffer-address in dependance of the connected screen to A000, B000 or
B800 and the videomode to 2, 3 or 7. Before using your software you should
try the command MODE CO80 or MODE BW80. We had a similar problem with 
Smalltalk 80 and the monochrom monitor from IBM. After setting the VGA-card 
to color-mode everything was ok.
