(BTW, I do believe the manual states that it is ignored if you have a VGA.) For example, Norton's SI returns 15.3 from a DOS window in Standard mode, and 4.6 from a full-screen DOS window in 386 mode. That's more than a 10% performance penalty. I have found that switching to Standard mode is my only choice for ru nning DOS apps. However, my friend's IBM Model 70 doesn't experience the same slowdown when running DOS apps in 386 mode; it's more like the 10% penalty that you suggest. (In real usage, I don't even notice a slowdown.) Now, does anybody know why I suffer a such a tremendous penalty, while my friend does not? Can anyone link it to the fact that I have an SX and he has a DX? ________________________________________________________________________ Michael B.
