Did I mention OpenGL?

From the ELSA Winner 2000PRO/X readme.txt file:

4.5     To use the hardware support of the DIVE interface, you must
        have 64MB of address space available in your system. This is
        determined and configured by the driver.  A failure will occur
        if any of the following conditions holds:

           a) PCI BUS computer :
                - more than 4031MB of address space used already
                  unlikely.
                  fix: none available
                - older system BIOS (non PCI-conforming)
                  fix: place the following line into your CONFIG.SYS:
                       SET VIDEO_APERTURE=A00
                  This allocated the 64MB Video aperture at 2,5GB in
                  your address space. Be sure this does not conflict
                  with address space requirements of other cards you
                  use.
           b) VL Bus computer :
                - more than 64MB of main memory
                  fix: none available
                - BIOS assigned an invaliued address
                  fix : add the following line to your CONFIG.SYS:
                        SET VIDEO_APERTURE=40
                  This assigns addresses following the first 64MB to
                  your video board.

6.4     Hardware video acceleration for the
           - ELSA VICTORY 3D
           - ELSA WINNER 3000S/M/L
           - ELSA WINNER 2000AVI/3D
        is only possible for one video at a time. Additional videos
        will be replayed using software motion video.

        fix: for optimal performance, finish one video before you
             start the next.

        In addition, the selected screen resolution should leave
        enough free video memory for storing a frame of the required
        resolution.  This will usually not be the case with a
        resolution of 800x600 at 32bpp with 2MB of video
        memory. Again, if the driver cannot use the hardware
        acceleration, it will revert to software motion video.

        fix: choose a graphics resolution smaller than the available
             maximum.

        When using these boards, hardware video shrinking will
        not function properly in all cases.

        The hardware video can be driven with max. 135MHz pixel-
        frequency. If the choosen videomode uses a higher pixelfrequency
        software motion video will be used.
        We recommend for video playback a resolution of 1024x768. Under
        this resolution the hardware video acceleration can be used in
        any colourmode and with high refreshrates.


From conversations I've had with some people I would expect OpenGL
acceleration for ELSA cards running under WARP in the near future.
