Add entries for the new driver to bdevsw and cdevsw tables in conf.c. - * You will need to make at least three routines: open(), close(), - * strategy() and possibly ioctl(). - * 2. Make attach() routine, which should allocate all the needed data - * structures and print the device description string (see xxxattach()). - * 3. Add an appropriate case to the switch in atapi_attach() routine, - * call attach() routine of the new driver here.
