There are video "modes". I know you can call up any character-cell video
mode with the mode command while in DOS. You need to know what modes
the Trident card supports, and there are Trident untilities you can download
that will either tell you the modes for your model, or read some info
from the
card and display the modes. This will get you the graphical modes as well.
I don't know how to force a DOS program to USE a specified mode, however.
It may have a line in some setup file that specifies the video mode to
be used.
If you specify a graphical mode while in DOS, there are a very few of them
that will actually work, but the screen update, and especially
scrolling, with be
laughably slow. Others will be refused, or crash the system.

Is this what you are talking about, the video mode in a CNC or CAD
application?
DOS video modes for character-cell and graphics are totally different. The
char-cell modes are used when in the command-line mode of DOS. The
graphical modes are generally only used by applications.

This is all horrible memories that I had hoped to never dredge up again!
