Hi
It looks like the gfx card doesn't support alpha. But DirectX should attempt to emulate this in software. You can see more info here (with screenshots)

Is anyone know where is problem with DirectX on this GFX card?
Kind regards from Poland

No, Direct3D doesn't try to emulate raster level operations in software. It would be far too slow. However, it should be possible to achieve the effect you're trying to get, simple alpha blended sprites, without using destination alpha.
A lot of professional developers consider embedded Intel graphics unacceptable for games, but a number of games, mostly ones at aimed at a wide audience, do support it. Your application seems to be well within it's capabilities.
According to the card caps listed in the thread referenced above, the graphics chip does support inverse source alpha for the destination blend mode factor. What it doesn't support is desination alpha, inverse or not, for either source or destination blend mode factor.
