### System Installation

The generic device handler, BVHINIT.DLL, is used primarily by system installation. It is also used for those situations when video devices have not been identified in the CONFIG.SYS file. It provides only the functions required for system installation and is otherwise device-independent.

Through VioGetConfig BVHINIT.DLL reports the highest function video adapter and display it can identify. It can identify only the MPA, CGA, EGA, VGA, 8514A, and XGA, along with their respective displays. Although it does not support mode and font setting, it attempts to load the 850 code page for the current EGA or VGA mode during system initialization.

If video devices have not been identified in the CONFIG.SYS file, the generic device handler attempts to load each of the following devices, until one is successfully loaded:

            GENERIC=DEVICE(BVHVGA,BVH8514A)
            GENERIC=DEVICE(BVHVGA)
            GENERIC=DEVICE(BVHEGA)
            GENERIC=DEVICE(BVHCGA)
            GENERIC=DEVICE(BVHINIT)
