- When you try and run certain applications in a window (which require
- certain video modes, particularly 256 color SuperVGA modes), OS/2 is
- unable to virtualize them (and may suspend the program). They do,
- however, run full screen. That's mainly a shortcoming of the PC
- architecture (and SuperVGA specifically).

- SVGA ON DOS should work. It will generate a SVGADATA.DOS file, which
- you can copy over as SVGADATA.PMI.

-
- I'll let someone else suggest a method -- I'm not yet completely
- familiar with the new SuperVGA driver support methods.
