Routine Description:

  Return the graphics image file named FileNameGuid into Image and return it's

  file name.

Arguments:

  FileNameGuid  - File Name of graphics file in the FV(s).

  Image         - Pointer to pointer to return graphics image.  If NULL, a 
                  buffer will be allocated.

  ImageSize     - Size of the graphics Image in bytes. Zero if no image found.


Returns: 

  EFI_SUCCESS          - Image and ImageSize are valid. 
  EFI_BUFFER_TOO_SMALL - Image not big enough. ImageSize has required size

Routine Description:

  Return the graphics image file named FileNameGuid into Image and return it's
  size in ImageSize. All Firmware Volumes (FV) in the system are searched for the
  file name.

Arguments:

  ImageHandle   - The driver image handle of the caller. The parameter is used to
                  optimize the loading of the image file so that the FV from which
                  the driver image is loaded will be tried first. 

  FileNameGuid  - File Name of graphics file in the FV(s).

  Image         - Pointer to pointer to return graphics image.  If NULL, a 
                  buffer will be allocated.

  ImageSize     - Size of the graphics Image in bytes. Zero if no image found.


Returns:

Routine Description:

  Convert a *.BMP graphics image to a GOP/UGA blt buffer. If a NULL Blt buffer
  is passed in a GopBlt buffer will be allocated by this routine. If a GopBlt
  buffer is passed in it will be used if it is big enough.

Arguments:

  BmpImage      - Pointer to BMP file

  BmpImageSize  - Number of bytes in BmpImage

  GopBlt        - Buffer containing GOP version of BmpImage.

  GopBltSize    - Size of GopBlt in bytes.

  PixelHeight   - Height of GopBlt/BmpImage in pixels

  PixelWidth    - Width of GopBlt/BmpImage in pixels


Returns: 

  EFI_SUCCESS           - GopBlt and GopBltSize are returned. 
  EFI_UNSUPPORTED       - BmpImage is not a valid *.BMP image
  EFI_BUFFER_TOO_SMALL  - The passed in GopBlt buffer is not big enough.
                          GopBltSize will contain the required size.
  EFI_OUT_OF_RESOURCES  - No enough buffer to allocate

Routine Description:
  Use Console Control Protocol to lock the Console In Spliter virtual handle. 
  This is the ConInHandle and ConIn handle in the EFI system table. All key
  presses will be ignored until the Password is typed in. The only way to
  disable the password is to type it in to a ConIn device.

Arguments:
  Password - Password used to lock ConIn device


Returns: 

  EFI_SUCCESS     - ConsoleControl has been flipped to graphics and logo
