Text-based adapters under MS-DOS don't need software drivers to interface between the operating system and the image on the screen. Windows, OS/2, and other graphics-rich environments do need drivers. In addition, controls are needed to adjust the refresh rate, resolution, and any special features the card offers. These needs are handled by the use of display drivers, a software layer that marries the card and monitor to the operating environment.
When installing a new card or operating system for a client, be sure to check the manufacturer's Web site for the latest display drivers. Not only will you reduce the likelihood of problems in using the new addition, but you will find that most new cards incorporate setup routines that can make quick work of getting a new display running.
