DX8 display modes

In the DirectX8 documentation about the D3DFORMAT type under Remarks it says: "Note that render target formats are restriced to D3DFMT_X1R5G5B5 D3DFMT_R5G6B5 D3DFMT_X8R8G8B8 D3DFMT_A8R8G8B8." Does that mean I can only create a device with a 16 or 32 bit display(as long as my video card supports it). What about 24 bit color or even D3DFMT_A1R5G5B5? When I enumerate the display modes am I guaranted to only get from 0 up to all of 4 of those modes and no more? Also on my machine under DirectDraw7 8, 16, 24, and 32 bpp display modes work just fine. When I enumerate display modes with Direct3D8 all I get are 16 bpp modes. What''s the deal? I have a VodooIII card.

The limitation on 16 bit or 32 bit render targets is, I believe a result of the integration of Direct 3D into direct x graphics, since most current 3d cards support only 16bit or 32 bit rendering. I don''t know why your voodoo 3 doesn''t show any 32 bit modes though.
