title: Lower Filter Driver
body: <p>How can I install a filter driver as lower filter driver? All samples of DDK are upper filter driver.
  Is there any method except using INF file for doing this work?
  I know that lower filter drivers sit under FDO and top of BDO, but if there are more that one lower filter driver, how they are ordered? Can I put my driver at a specific location of this stack?</p>
