The information in this article applies to:
  • Microsoft Windows operating system versions 3.0, 3.0a, 3.1, 3.11
  • Microsoft Word for Windows, versions 1.0, 1.1, 1.1a, 2.0, 2.0a, 2.0b, 2.0c

When you use a Video Seven FastWrite VGA, V-RAM VGA, or VGA 1024i video card in 386 enhanced mode Windows with the Windows VGA driver, the following line must be added to the [386Enh] section of the SYSTEM.INI file: 

   EMMExclude=C600-C7FF
This switch is required because the Video Seven cards use this segment of memory, but the segment appears free to Windows. Thus, Windows may use this segment for its high-memory page mapping and conflict with the Video Seven card.
