Subject : OS2 2.0 32-bit Graphics Engine/Windows 3.1 Beta Program

September 16, 1992

IBM is initiating a beta program to obtain testing and development
feedback for the OS/2 32-Bit Graphics Engine and WIN-OS/2 Version
3.1 capabilities. The code is being made available for testing
and development feedback purposes only, and should NOT be used in
production.

The 32-bit Graphics Engine is a full 32 bit implementation of the
OS/2 2.0 Graphics Engine and Graphics Programming interface. It
includes a full 32 bit implementation of the XGA and VGA device
drivers, and is fully compatible with existing 16 bit device
drivers. New features that developers can now take advantage of
are increased system limits for graphic objects and handles and
support for Palette Management on XGA adapters. The 32-bit
Graphics Engine will be of interest to OS/2 2.0 users who need to
evaluate Seamless PM/Windows Mode with high resolution (1024x768)
XGA and selected SVGA support.

WIN-OS/2 Version 3.1 provides the ability to run Windows**
Standard Mode applications which should execute with improved
performance and application integrity over WIN-OS/2 Version 3.0.
It includes support for the level of display and printer drivers
that were shipped with Microsoft** Windows 3.1, as well as the
3.1 level of support for Object Linking and Embedding (OLE) and
Dynamic Data Exchange (DDE). New features include Seamless
PM/Windows execution on XGA, and unique AUTOEXEC.BAT files per
VDM. WIN-OS/2 Version 3.1 requires the accompanying 32-bit
Graphics Engine to run.

PREREQUISITES
- Requires a test system capable of executing OS/2 Version 2.0
- Does not support installing over OS/2 1.3 or OS/2 2.0. You
