The first installation result was a little dissapointing, because of two points:
- there is only a standard video driver for my ati radeon graphic with a limited support for resolution options
- the sounds did not work
Point 2. is working now. I downloaded the old audio-sigmatel-driver from dell-support (for win XP). Cancel the Installation when it is extracted on disk. Go to the device Manager. Select the audio question mark and choose „install driver from disk“ and point to the extracted files.
