summary of what i did so far: i installed debian on the tablet but it seemed like while boot the display gets turned off, even with ctrl + alt + f1 i didn't see anything, anyway i managed to copy the 3 files to the bootpartition from a usb-stick, from which i booted the debian live cd, then my cable got a loose contact so i decided to copy the tarball to the sdcard and start the copyingprocess, but unfortunately i couldn't make contact with the cable, so i couldn't use the keyboard. next i will buy a new usb-cable and copy the files to the datapartition. then hopefully it will boot
