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. 
 

 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.
