发明名称 File-based video display mode setup
摘要 A computer system and method of operating the same to setup a graphics display driver and device are disclosed. The disk storage of the computer system contains a monitor file that specifies various video modes operable by a number of monitor types and models, and also contains a mode file that specifies the video modes operable by a number of graphics controllers. The mode file also contains the video parameters for each of the available video modes. During a setup routine, the computer system determines the monitor and graphics controller that are installed, and for each available driver program, selects a video mode compatible with each; if more than one video mode is compatible, the computer system may select the best video mode. Upon selection of the video mode, and upon installation of the driver, the computer system reads the video parameters from the mode file for the selected mode, such video parameters stored in an interpretive language, and executes the program in order to program the graphics controller according to the video parameters. This arrangement eliminates the need to maintain the video parameters in the driver executable, and thus facilitates configuration and maintenance of the computer system.
