here are the Command Line Options for the NEW Direct X 9.0b redist package. I downloaded it today and recovered the switches with this command line switch c:>dx90update_redist /? the reply was /Q -- Quiet modes for package, /T:<full path> -- Specifies temporary working folder, /C -- Extract files only to the folder when used also with /T. /C:<cmd> -- Override Install Command defined by author. Which are basically the same for a TYPE 2 package. So i'd try "/Q:A /R:N" for the switches in your .inf file
