everything done
installed the graphic drivers and the sound drivers and everything works now, full graphic and full sound
thank you so much
in osx i use a program called Boxer, it create games packages that contain dosBox itself (i suppose) and the program files and so they run just with a double click so i decided to install drivers inside that package instead of the CVS build, and also i haven't find an osx version of the CVS build that AlumiuN suggested, just windows and linux. maybe the linux version also works in osx but i preferred the driver installation method so i can have the double-click-and-run feature provided by Boxer.
thanks again to all of you
