My bad, I must have looked at a different Atom board... :-[ >We use our proprietary software which controls external I/O board >trough printer port at address 378.

As you are not sure what port it might be using and just assuming that it uses 378h is certainly wrong, have you checked with what value is in the BIOS data segment at 0040h:0008h? That should tell you what the (first) parallel ports actual base address supposed to be. Chances are, it might be for example 3BCh, as with PS/2 or Compaq computers >About the graphics.

Certainly nothing that FreeDOS has an influence on. Any character mapping features are video BIOS dependent, not DOS...
