About This Book
The Graphics Adapter Device Driver (GRADD) Reference supports OS/2 Warp on the Intel hardware platform. The information in this book describes the GRADD driver model, how the related components work together, and why the GRADD model enhances OS/2 Warp device-driver support.
Detailed descriptions of control structures, data structures, and I/O formats have been included to help you understand and use the interfaces.
Developers using this book should be familiar with the C or assembler programming language and the OS/2 operating system.
How This Book is Organized
This book includes the following chapters and supporting appendixes:
- Introduction to Graphics Adapter Device Drivers
- This chapter briefly describes the design philosophy of the GRADD Model.
- GRADD Model Components
- This chapter provides details on each of the components and how they work together within the GRADD Model.
- Video Manager
- This chapter contains a list of the Video Manager Interface functions, as well as a detailed description of each.
- Graphics Adapter Device Drivers
- This chapter describes the device driver interface (DDI) for a GRADD, how and when to add extensions, and detailed description of each Graphics Hardware Interface function. In addition, this chapter describes the Enhanced Direct Interface Video Extension (EnDIVE) functions.
- VIDEOPMI.DLL Exported Functions
- This chapter describes the format and syntax used to define the data necessary to set a video mode while in OS/2 Protect Mode. It also includes the APIs.
- VIDEO Protect-Mode Interface
- This chapter discusses the purpose of the VIDEO Protect-Mode Interface (PMI) used in IBM Operating System/2. It is an extension of the VESA SVPMI standard currently in use by the operating system's base and virtual video subsystems. The PMI provides a means of setting Super VGA video modes while in Protect Mode and of enabling their virtualization in multiple DOS sessions.
- Installing Video Configuration Manager for OS/2
- This chapter discussed the Video Configuration Manager (VCMAN), the OS/2 operating-system-service module VIDEOCFG.DLL, how video installation and configuration information is stored in a persistent namespace in the Registry; this discussion includes the functions used to install and configure video adapters and monitors.
Appendixes
- Appendix A. OS/2 Version Compatibility Considerations
- This appendix describes information in terms of version compatibility.
- Appendix B. Syntax Conventions
- This appendix indicates the conventions that have been used for the parameter names found in the data types.
- Appendix C. Data Types
- This appendix contains a description of the parameters for all the data types called by the Video Manager Interface, the Graphics Hardware Interface, the Video Configuration Manager, and the Protect-Mode Interface.
- Appendix D. Notices
- This appendix contains legal notices.
- Miscellaneous
- A glossary and an index are included.
