-In the last lesson we've discovered that our system has BGRT ACPI table.
-
-According to the ACPI specification:
-```
-The Boot Graphics Resource Table (BGRT) is an optional table that provides a mechanism to indicate that
-an image was drawn on the screen during boot, and some information about the image.
-The table is written when the image is drawn on the screen. This should be done after it is expected that
-any firmware components that may write to the screen are done doing so and it is known that the image
-is the only thing on the screen. If the boot path is interrupted (e.g., by a key press), the valid bit within the
-status field should be changed to 0 to indicate to the OS that the current image is invalidated
-```
-This table actually have a pointer to image data, check structure definition under https://github.com/tianocore/edk2/blob/master/MdePkg/Include/IndustryStandard/Acpi63.h:
-```
-///
-/// Boot Graphics Resource Table definition.
-///
-typedef struct {
-  EFI_ACPI_DESCRIPTION_HEADER Header;
-  ///
-  /// 2-bytes (16 bit) version ID. This value must be 1.
-  ///
-  UINT16                      Version;
-  ///
-  /// 1-byte status field indicating current status about the table.
-  ///     Bits[7:1] = Reserved (must be zero)
-  ///     Bit [0] = Valid. A one indicates the boot image graphic is valid.
-  ///
-  UINT8                       Status;
-  ///
-  /// 1-byte enumerated type field indicating format of the image.
-  ///     0 = Bitmap
-  ///     1 - 255  Reserved (for future use)
-  ///
-  UINT8                       ImageType;
-  ///
-  /// 8-byte (64 bit) physical address pointing to the firmware's in-memory copy
-  /// of the image bitmap.
-  ///
-  UINT64                      ImageAddress;
-  ///
-  /// A 4-byte (32-bit) unsigned long describing the display X-offset of the boot image.
-  /// (X, Y) display offset of the top left corner of the boot image.
-  /// The top left corner of the display is at offset (0, 0).
-  ///
-  UINT32                      ImageOffsetX;
-  ///
-  /// A 4-byte (32-bit) unsigned long describing the display Y-offset of the boot image.
-  /// (X, Y) display offset of the top left corner of the boot image.
-  /// The top left corner of the display is at offset (0, 0).
-  ///
-  UINT32                      ImageOffsetY;
-} EFI_ACPI_6_3_BOOT_GRAPHICS_RESOURCE_TABLE;
-```
-
-
-Let's create an app that would save an image from BGRT.
-
-This time to get BGRT table we would utilize `EFI_ACPI_SDT_PROTOCOL` protocol.
-
-To get ACPI table data we would use `GetAcpiTable()` function from this protocol:
-```
-EFI_ACPI_SDT_PROTOCOL.GetAcpiTable()
-
-Summary:
-Returns a requested ACPI table.
-
-Prototype:
-typedef
-EFI_STATUS
-(EFIAPI *EFI_ACPI_GET_ACPI_TABLE) (
- IN UINTN Index,
- OUT EFI_ACPI_SDT_HEADER **Table,
- OUT EFI_ACPI_TABLE_VERSION *Version,
- OUT UINTN *TableKey
- );
-
-Parameters:
-Index		The zero-based index of the table to retrieve.
-Table		Pointer for returning the table buffer.
-Version		On return, updated with the ACPI versions to which this table belongs.
-TableKey	On return, points to the table key for the specified ACPI system definition table.
-
-Description:
-The GetAcpiTable() function returns a pointer to a buffer containing the ACPI table associated with the Index that was input. The following structures are not considered elements in the list of ACPI tables:
-- Root System Description Pointer (RSD_PTR)
-- Root System Description Table (RSDT)
-- Extended System Description Table (XSDT)
-```
-In edk2 it is defined here: https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Protocol/AcpiSystemDescriptionTable.h
-
-To get all tables we need to call `GetAcpiTable` with incrementing values for `Index` starting with 0, while function returns `EFI_SUCCESS`.
-
-On every success call we would get a pointer to a common header for a ACPI table:
-```
-typedef struct {
- UINT32 Signature;
- UINT32 Length;
- UINT8 Revision;
- UINT8 Checksum;
- CHAR8 OemId[6];
- CHAR8 OemTableId[8];
- UINT32 OemRevision;
- UINT32 CreatorId;
- UINT32 CreatorRevision;
-} EFI_ACPI_SDT_HEADER;
-```
-
-To use `EFI_ACPI_SDT_PROTOCOL` we need to add include to our file:
-```
-#include <Protocol/AcpiSystemDescriptionTable.h>
-```
-And add protocol to the *.inf file:
-```
-[Protocols]
-  gEfiAcpiSdtProtocolGuid
-```
-
-Here is a code finding BGRT ACPI table:
-```
-EFI_ACPI_SDT_PROTOCOL* AcpiSdtProtocol;
-EFI_STATUS Status = gBS->LocateProtocol (
-                &gEfiAcpiSdtProtocolGuid,
-                NULL,
-                (VOID**)&AcpiSdtProtocol
-                );
-if (EFI_ERROR (Status)) {
-  return Status;
-}
-
-BOOLEAN BGRT_found = FALSE;
-UINTN Index = 0;
-EFI_ACPI_SDT_HEADER* Table;
-EFI_ACPI_TABLE_VERSION Version;
-UINTN TableKey;
-while (TRUE) {
-  Status = AcpiSdtProtocol->GetAcpiTable(Index,
-    &Table,
-    &Version,
-    &TableKey
-  );
-  if (EFI_ERROR(Status)) {
-    break;
-  }
-  if (((CHAR8)((Table->Signature >>  0) & 0xFF) == 'B') &&
-      ((CHAR8)((Table->Signature >>  8) & 0xFF) == 'G') &&
-      ((CHAR8)((Table->Signature >> 16) & 0xFF) == 'R') &&
-      ((CHAR8)((Table->Signature >> 24) & 0xFF) == 'T')) {
-    BGRT_found = TRUE;
-    break;
-  }
-  Index++;
-}
-if (!BGRT_found) {
-  Print(L"BGRT table is not present in the system\n");
-  return EFI_UNSUPPORTED;
-}
-```
-
-Now we need to save an image from BGRT table.
-
-Currently ACPI specification support only BMP image type https://uefi.org/specs/ACPI/6.4/05_ACPI_Software_Programming_Model/ACPI_Software_Programming_Model.html#image-type
-
-So first we check if the type is actually BMP:
-```
-EFI_ACPI_6_3_BOOT_GRAPHICS_RESOURCE_TABLE* BGRT = (EFI_ACPI_6_3_BOOT_GRAPHICS_RESOURCE_TABLE*)Table;
-if (BGRT->ImageType == 0) {
-  ...
-}
-```
-
-Now we need to actually save a BMP image. BGRT doesn't contain any size for an image, only offset to data: `ImageAddress`.
-
-To get image size we need to look at BMP header. 
-
-In edk2 it is defined under https://github.com/tianocore/edk2/blob/master/MdePkg/Include/IndustryStandard/Bmp.h:
-```
-typedef struct {
-  CHAR8         CharB;
-  CHAR8         CharM;
-  UINT32        Size;
-  UINT16        Reserved[2];
-  UINT32        ImageOffset;
-  UINT32        HeaderSize;
-  UINT32        PixelWidth;
-  UINT32        PixelHeight;
-  UINT16        Planes;          ///< Must be 1
-  UINT16        BitPerPixel;     ///< 1, 4, 8, or 24
-  UINT32        CompressionType;
-  UINT32        ImageSize;       ///< Compressed image size in bytes
-  UINT32        XPixelsPerMeter;
-  UINT32        YPixelsPerMeter;
-  UINT32        NumberOfColors;
-  UINT32        ImportantColors;
-} BMP_IMAGE_HEADER;
-```
-
-Don't forget to include this file in our program:
-```
-#include <IndustryStandard/Bmp.h>
-```
-
-When we know that the image is BMP, we can check its signature (`BM`), parse its size and actually write its data to a file. Here we use `EFI_STATUS WriteFile(CHAR16* FileName, VOID* Data, UINTN* Size)` function to write data to a file, we will define it in a minute:
-```
-BMP_IMAGE_HEADER* BMP = (BMP_IMAGE_HEADER*)(BGRT->ImageAddress);
-
-if ((BMP->CharB != 'B') || (BMP->CharM != 'M')) {
-  Print(L"BMP image has wrong signature!\n");
-  return EFI_UNSUPPORTED;
-}
-Print(L"BGRT conatins BMP image with %dx%d resolution\n", BMP->PixelWidth, BMP->PixelHeight);
-UINTN Size = BMP->Size;
-Status = WriteFile(L"BGRT.bmp", BMP, &Size);
-if (EFI_ERROR(Status)) {
-  Print(L"Error! Can't write BGRT.bmp file\n");
-}
-```
-
-Last time we've used `EFI_SHELL_PROTOCOL` to create a file and write data to it. This time we will try to utilize ShelLib:
-
-https://github.com/tianocore/edk2/blob/master/ShellPkg/Include/Library/ShellLib.h
-
-https://github.com/tianocore/edk2/blob/master/ShellPkg/Library/UefiShellLib/UefiShellLib.c
-
-Again we will need 3 functions: for file open, write and close:
-```
-/**
-  This function will open a file or directory referenced by filename.
-  If return is EFI_SUCCESS, the Filehandle is the opened file's handle;
-  otherwise, the Filehandle is NULL. Attributes is valid only for
-  EFI_FILE_MODE_CREATE.
-  @param[in] FileName           The pointer to file name.
-  @param[out] FileHandle        The pointer to the file handle.
-  @param[in] OpenMode           The mode to open the file with.
-  @param[in] Attributes         The file's file attributes.
-  ...
-**/
-
-EFI_STATUS
-EFIAPI
-ShellOpenFileByName(
-  IN CONST CHAR16               *FileName,
-  OUT SHELL_FILE_HANDLE         *FileHandle,
-  IN UINT64                     OpenMode,
-  IN UINT64                     Attributes
-  );
-```
-```
-/**
-  Write data to a file.
-  This function writes the specified number of bytes to the file at the current
-  file position. The current file position is advanced the actual number of bytes
-  written, which is returned in BufferSize. Partial writes only occur when there
-  has been a data error during the write attempt (such as "volume space full").
-  The file is automatically grown to hold the data if required. Direct writes to
-  opened directories are not supported.
-  @param[in] FileHandle          The opened file for writing.
-  @param[in, out] BufferSize     On input the number of bytes in Buffer.  On output
-                                 the number of bytes written.
-  @param[in] Buffer              The buffer containing data to write is stored.
-  ...
-**/
-
-EFI_STATUS
-EFIAPI
-ShellWriteFile(
-  IN SHELL_FILE_HANDLE          FileHandle,
-  IN OUT UINTN                  *BufferSize,
-  IN VOID                       *Buffer
-  );
-```
-```
-/**
-  Close an open file handle.
-  This function closes a specified file handle. All "dirty" cached file data is
-  flushed to the device, and the file is closed. In all cases the handle is
-  closed.
-  @param[in] FileHandle           The file handle to close.
-**/
-
-EFI_STATUS
-EFIAPI
-ShellCloseFile (
-  IN SHELL_FILE_HANDLE          *FileHandle
-  );
-```
-
-Advantage of using `ShellLib` is that now we don't need to find `EFI_SHELL_PROTOCOL` and work with it manually.
-
-
-Our `WriteFile` function would look like this:
-```
-EFI_STATUS WriteFile(CHAR16* FileName, VOID* Data, UINTN* Size)
-{
-  SHELL_FILE_HANDLE FileHandle;
-  EFI_STATUS Status = ShellOpenFileByName(
-    FileName,
-    &FileHandle,
-    EFI_FILE_MODE_CREATE | EFI_FILE_MODE_WRITE | EFI_FILE_MODE_READ,
-    0
-  );
-  if (!EFI_ERROR(Status)) {
-    Print(L"Save it to %s\n", FileName);
-    UINTN ToWrite = *Size;
-    Status = ShellWriteFile(
-      FileHandle,
-      Size,
-      Data
-    );
-    if (EFI_ERROR(Status)) {
-      Print(L"Can't write file: %r\n", Status);
-    }
-    if (*Size != ToWrite) {
-      Print(L"Error! Not all data was written\n");
-    }
-    Status = ShellCloseFile(
-      &FileHandle
-    );
-    if (EFI_ERROR(Status)) {
-      Print(L"Can't close file: %r\n", Status);
-    }
-  } else {
-    Print(L"Can't open file: %r\n", Status);
-  }
-  return Status;
-}
-```
-
-To use ShellLib we need to include a header in our program:
-```
-#include <Library/ShellLib.h>
-```
-
-Also we need to add `ShellPkg.dec` to our packages and add `ShellLib` to our library classes:
-```
-[Packages]
-  MdePkg/MdePkg.dec
-+  ShellPkg/ShellPkg.dec
-
-[LibraryClasses]
-  UefiApplicationEntryPoint
-  UefiLib
-+  ShellLib
-```
-Besides that our package `*.dsc` file needs to include a `ShellLib` library class:
-```
-[LibraryClasses]
-  ...
-  ShellLib|ShellPkg/Library/UefiShellLib/UefiShellLib.inf
-```
-
-Unfortunately this is not enough, our current build would fail with a message, because `ShellLib` by itself needs another library:
-```
-build.py...
-/home/kostr/tiano/edk2/UefiLessonsPkg/UefiLessonsPkg.dsc(...): error 4000: Instance of library class [FileHandleLib] is not found
-```
-
-To find it use our standard tactic:
-```
-$ grep FileHandleLib -r ./ --include=*.inf | grep LIBRARY_CLASS
-```
-
-In the end we had to add several more LibraryClasses to make our build succeed:
-```
-[LibraryClasses]
-  ...
-  FileHandleLib|MdePkg/Library/UefiFileHandleLib/UefiFileHandleLib.inf
-  HiiLib|MdeModulePkg/Library/UefiHiiLib/UefiHiiLib.inf
-  SortLib|MdeModulePkg/Library/UefiSortLib/UefiSortLib.inf
-  UefiHiiServicesLib|MdeModulePkg/Library/UefiHiiServicesLib/UefiHiiServicesLib.inf
-```
-
-Build our app and execute it under OVMF:
-```
-FS0:\> SaveBGRT.efi
-BGRT conatins BMP image with 193x58 resolution
-Save it to BGRT.bmp7
-FS0:\>
-```
-
-If you look at the BGRT.bmp picture that are app have produced, it would have the same content as https://raw.githubusercontent.com/tianocore/edk2/master/MdeModulePkg/Logo/Logo.bmp
-
-The file itself wouldn't be the same since BGRT driver don't use an image from flash, but actually grabs a boot screen and transforms it to a BMP image. For the proof checkout how https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Universal/Acpi/BootGraphicsResourceTableDxe/BootGraphicsResourceTableDxe.c uses `TranslateGopBltToBmp` function from the https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Library/BaseBmpSupportLib/BmpSupportLib.c library.
-If you find it strange that BGRT grabs a screen instead of using an image from flash, remember how BGRT is defined in ACPI specification:
-```
-The Boot Graphics Resource Table (BGRT) is an optional table that provides a mechanism to indicate that an image was drawn on the screen during boot
-```
-
-The file GUID for binary boot logo image is defined in the file https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Logo/Logo.inf
-```
-FILE_GUID                      = 7BB28B99-61BB-11D5-9A5D-0090273FC14D
-```
-It is a GUID that is usually used for the Logo image in BIOS. It is even hardcoded to https://github.com/tianocore/edk2/blob/master/BaseTools/Source/Python/Eot/Report.py
-```
-## GenerateFfs() method
-#
-#  Generate FFS information
-#
-#  @param self: The object pointer
-#  @param FfsObj: FFS object after FV image is parsed
-#
-def GenerateFfs(self, FfsObj):
-    self.FfsIndex = self.FfsIndex + 1
-    if FfsObj is not None and FfsObj.Type in [0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0xA]:
-        FfsGuid = FfsObj.Guid
-        FfsOffset = FfsObj._OFF_
-        FfsName = 'Unknown-Module'
-        FfsPath = FfsGuid
-        FfsType = FfsObj._TypeName[FfsObj.Type]
-
-        # Hard code for Binary INF
-        if FfsGuid.upper() == '7BB28B99-61BB-11D5-9A5D-0090273FC14D':
-            FfsName = 'Logo'
-
-        if FfsGuid.upper() == '7E374E25-8E01-4FEE-87F2-390C23C606CD':
-            FfsName = 'AcpiTables'
-
-        if FfsGuid.upper() == '961578FE-B6B7-44C3-AF35-6BC705CD2B1F':
-            FfsName = 'Fat'
-        ...
-```
