Last reviewed: November 22, 1994
Article ID: Q58303

The information in this article applies to:

Microsoft Windows operating system versions 3.0, 3.0a, 3.1, 3.11

For proper operation in Microsoft Windows 386 enhanced mode on the AST VGA Plus card, the following line is required in the [386Enh] section of the SYSTEM.INI file:

   EMMEXCLUDE=C000-C500

This requirement is due to nonstandard ROM mapping by the AST VGA Plus.

If this line is not included, the system may stop responding (hang or lock up) when starting or running Windows in 386 enhanced mode.
