Yes I know of MSDN but it doesn''t quite explain what it does
This is from the MSDN about that mipmap flag (from surface7 caps)

DDSCAPS_MIPMAP
This surface is one level of a mipmap. This surface is attached to other DDSCAPS_MIPMAP surfaces to form the mipmap. This can be done explicitly by creating a number of surfaces and attaching them by using the IDirectDrawSurface7::AddAttachedSurface method, or implicitly by the CreateSurface method. If this capability is set, DDSCAPS_TEXTURE must also be set.

However, I don''t think this is what it means in the Surface Caps Bits in the DDraw Caps Viewer (comes with DX7 SDK).. Go fire up the DD Caps Viewer-> Driver->Driver Surface Caps -> MIPMAP

If it does, then it''s real freaky cause I cannot get D3DXCreateTextureFromFile to create mipmaps (there is no error reported) and the checkbox for MIPMAP is ticked...
