Hi erik_demon! The repeated 45 is my fault... it was only to show the structure, i already changed it. So I will delete the line as you said. One more question (forgive me, but i`m really interested on making the thing happen): If I delete the DEL /Q $OEM$\$1\D\BTS_DPs_cleanup.cmd I still need to do the presetup.cmd and create the keep_the_drivers.cmd that you posted? Do I really need to copy the drivers to my system? Is there any possibility to only install the drivers and then remove it after? Or install from CD directly don`t even needing to copy the drivers to the system. And how can i do these? thanks
