Egbert,

Thank you for your answer. Furthermore I have to ask one more question.
This 2D acceleration however works with W2K and therefore seems to be
possible to develop. Is this current situation purely result of lack of
documentation to this chip and/or developing a driver would require
exhausting amount of testing and workarounds?

Cheers, Christer
