  Name:         OSi_LoadImage

  Description:  Loads an image file (provisional). NOTE: This function actually just returns a pointer.

  Arguments:    index: Index to the file to load
                p_size: Pointer to u32 that stores the file size
                            If not needed, specify NULL, and it will be ignored.

  Returns:      Returns the starting address of the image data.
