Contains the macros and constants used to define I/O control codes.


Contains the basic types, constants, and structures for video (and SCSI) miniport drivers.


Contains the system-defined I/O control codes (IOCTLs) and corresponding structures that are sent in video request packets (VRPs) to video miniport drivers.


Contains the VIDEOPARAMETERS structure used to implement TV connector and copy protection support and the constants used in this structure.


Contains the VideoPortXxx and SvgaHwIoPortXxx video port function declarations, video-specific structures, such as the VIDEO_REQUEST_PACKET, and the HwVidXxx video miniport function prototypes.
