       /DRIVERNAME=driver

    Specifies the name of the driver as recorded in the prolog table.
    If the driver has not been loaded, the system acts as if the
    driver name is also the name of an executable image (file type
    .EXE) in the SYS$LOADABLE_IMAGES directory and loads the driver.
    The driver name defaults to the first two characters of the
    device name concatenated with "DRIVER" (for example, LPDRIVER).
