 * }

Q66962

-

The information in this article applies to:


 * Microsoft Windows versions 3.0, 3.0a

-

SYMPTOMS
To run Microsoft Windows version 3.0 in 386 enhanced mode on a Dell 316LT, 316SX, or 320LT laptop computer, the following EMMExclude lines under the [386ENH] section of the SYSTEM.INI file are required:

  EMMExclude = E000 - EFFF EMMExclude = C000 - C7FF

MORE INFORMATION
These high-memory page segments are used for extended video RAM and RAM BIOS shadowing. However, the segments may appear to be free when Windows starts in 386 enhanced mode. Windows may attempt to use these memory segments while operating, which will corrupt the video RAM or the BIOS shadowing. This may cause UAEs, crashing, or lock-ups of the I/O devices (keyboard, mouse, and so on).
