The DIVE architecture has been enhanced in OS/2 Version 3 to support motion video accelerator hardware. This enhanced architecture is called EnDIVE. It provides additional DEVESC_ functions for querying information about the color formats supported by the hardware, video memory management and image processing.

The Display Engine detects and uses acceleration hardware (via EnDIVE) and substitutes software algorithms whenever necessary.

The DIVE and EnDIVE DEVESC_ functions are listed below:

• GreEscape DEVESC_ACQUIREFB
  
• GreEscape DEVESC_DEACQUIREFB
  
• GreEscape DEVESC_EXTGET
  
• GreEscape DEVESC_EXTPUT
  
• GreEscape DEVESC_EXTQUERY
  
• GreEscape DEVESC_GETAPERTURE
  
• GreEscape DEVESC_HWREQUEST
  
• GreEscape DEVESC_QUERYFB
  
• GreEscape DEVESC_REGISTER
  
• GreEscape DEVESC_SETUPBLITTERNOTIFY
  
• GreEscape DEVESC_SWITCHBANK
  
• GreEscape DEVESC_VIDEOHIDDEN
  
• GreEscape DEVESC_VRAMALLOC

For detailed information about the DIVE architecture, refer to the OS/2 Multimedia Application Programming Guide and to the individual functions included in Mandatory and Simulated Graphics Engine Function Reference. The functions are listed alphabetically in the index table for that chapter.
