- I played with Linux the other day and xterm scrolling shits all over OS/2.
- It doesn't update after every single line which makes a very big

- I disabled VIDEO EMULATION in DOS sessions and got a factor of 4 to 8
- improvement immediately. Seems, as expected, that the ET4000 scrolling
- (without coprocessor) is a lot better than OS/2's DOS scrolling. Only
- problem is that I can't see any way of persuading it to do the same thing
- for OS/2 windows.
