Q3.0.8: How do I get a single minibuffer frame?

     (setq initial-frame-plist '(minibuffer nil))

     (setq default-minibuffer-frame
           (make-frame
            '(minibuffer only
                         width 86
                         height 1
                         menubar-visible-p nil
                         default-toolbar-visible-p nil
                         name "minibuffer"
                         top -2
                         left -2
                         has-modeline-p nil)))
     (frame-notice-user-settings)

Please note: The single minibuffer frame may not be to everyone's taste, and there any number of other SXEmacs options settings that may make it difficult or inconvenient to use.
