Installing Ubuntu 6.06, 6.10 or Feisty on Medion MD 8818 ML not working. No Hardware recognition. Fake Raid problem?

Hi everybody,
I bought the new (Aldi) PC Medion MD 8818 ML last december. Windows XP preinstalled, and I don't like it, but still have to use it for professional reasons. But No Way to install Ubuntu, Redhat, Suse or whatever Linux, because Harddisks are not found - so I can't format them. Is this a virtual SATA problem, as somebody says? How to fix it? What can I do?
And please, if giving me any advice regarding BIOS, please tell me, how to get into Bios and what to do exactly ... I am more a simple user than a programmer ...
But I have some prior experience regarding Ubuntu 6.06, as I installed and configured it and worked with it successfully on another PC (by Gericom).
I even succeeded there in getting my usb-TV Card to work ...
But now? I am clueless and the hints in the web regarding my problem didn't really help a bit.
