In fact, our posting guidelines require you to read the manual before asking questions. Moreover, most of the questions you have asked recently have nothing to do with installation, which is the subject of this forum. I think whatever useful purpose may have been served by this thread is now exhausted, so I am going to close the thread.
Per our posting guidelines, if you have questions about specific Rockbox features, you should (1) read the manual, and (2) search these forums. If you cannot find an answer from either of those two sources, then (and only then) may you start another thread specific to that question.
