Download the mmc.zip file from ViX (see link above) and copy to the HDD (I think ATV use images directory but it should find it on the HDD). Then in Flash online (long press blue button, I believe). ... and it should find the zip. Then flash one of the slots. In ViX you can choose in ImageManager to download and flash images from ViX and OpenATV (OPenPli don‘t support the box)
