- WOW! I tried this in 800x600x256 mode, and it does work. Scrolling in
- a DOS window is now very good.
-
- Now is there anyway for OS/2 windows to take advantage of this?

- twice as fast!

- yes. If my mangy old Trident (which is a nice enough card) can be useful
- for a while longer, I will be very happy. I hate knowing that the
