Microsoft Intel DCI Specification v1.4
This is the "Microsoft Intel Display Control Interface", version 1.4, dated June 13, 1994. The DCI for the Microsoft Windows operating system is a driver-level software interface which provides access to display devices while maintaining compatibility with Windows GDI. It provides a device-independent way for Windows subsystem software such as 3-D graphics packages, games interface packages, or digital video codecs to access display device-dependent features. Applications should be using WinG and Video for Windows, which will use DCI or other methods to communicate efficiently with the hardware, and also work on Windows NT. DCI works with Windows 3.1 and will work with Windows "Chicago"; due to architectural differences, Windows NT does not support DCI, which is under consideration. This specification provides information for implementing and using DCI. Dci.zip contains dci.doc, a Microsoft Word document.
