I extracted these from Samsung KIES so you can install the drivers without the whole application.
As the dvr5700.zip from the board doesn't work on a fresh formatted system
I thought this could help those who don't want Samsung's own applictaions installed or to download a ~200mb app.
The file is an original installer so you don't have to manually add the drivers.
MOD, please feel free to move this thread if it doesn't belong here.
