This file is the Base Video Handler for OS/2. Any OS/2 application that sets a video mode calls this DLL. In mode cases, however, the only application that sets any video modes is the PM display driver and the MODE.COM utility (for setting 132 column modes). The first time this DLL would be called is after the OS/2 bitmap logo appears (PM starts up then). This DLL is specified in the CONFIG.SYS in the following manner:
SET VIO_VGA=DEVICE(BVHVGA,BVHSVGA)
BVHVGA is used to set, save, and restore VGA modes, BVHSVGA for SVGA modes.
