OVERVIEW
The UEFI 2.0 shell provides a standard pre-boot command line processor.
It is similar to the EDK EFI Shell or a *nix command line parser.

HOW TO INCORPORATE THIS SHELL INTO NT32
The instructions below are included as a sample and template on how a
developer may integrate this code into an existing platform:

1. Add this shell build to the build:
   Add the shell.inf to the [components] section as it is in the ShellPkg.dsc.
   EXAMPLE: to add the shell to Nt32 emulation, edit file "Nt32Pkg.dsc" add the following .inf 
                to the [Components...] section and before the [BuildOptions] Section
_______
  ShellPkg/Application/Shell/Shell.inf {
   
      DebugLib|MdePkg/Library/UefiDebugLibConOut/UefiDebugLibConOut.inf
      ShellCommandLib|ShellPkg/Library/UefiShellCommandLib/UefiShellCommandLib.inf
      NULL|ShellPkg/Library/UefiShellLevel2CommandsLib/UefiShellLevel2CommandsLib.inf
      NULL|ShellPkg/Library/UefiShellLevel1CommandsLib/UefiShellLevel1CommandsLib.inf
      NULL|ShellPkg/Library/UefiShellLevel3CommandsLib/UefiShellLevel3CommandsLib.inf
      NULL|ShellPkg/Library/UefiShellDriver1CommandsLib/UefiShellDriver1CommandsLib.inf
      NULL|ShellPkg/Library/UefiShellInstall1CommandsLib/UefiShellInstall1CommandsLib.inf
      NULL|ShellPkg/Library/UefiShellDebug1CommandsLib/UefiShellDebug1CommandsLib.inf
      NULL|ShellPkg/Library/UefiShellNetwork1CommandsLib/UefiShellNetwork1CommandsLib.inf
      HandleParsingLib|ShellPkg/Library/UefiHandleParsingLib/UefiHandleParsingLib.inf
      FileHandleLib|ShellPkg/Library/UefiFileHandleLib/UefiFileHandleLib.inf
      ShellLib|ShellPkg/Library/UefiShellLib/UefiShellLib.inf
      SortLib|ShellPkg/Library/UefiSortLib/UefiSortLib.inf
      PrintLib|MdePkg/Library/BasePrintLib/BasePrintLib.inf


   
      gEfiMdePkgTokenSpaceGuid.PcdDebugPropertyMask|0xFF
      gEfiShellPkgTokenSpaceGuid.PcdShellLibAutoInitialize|FALSE
      gEfiMdePkgTokenSpaceGuid.PcdUefiLibMaxPrintBufferSize|16000
  }
_________

2. Update system PCDs in the .dsc file  to support this new module
   Update the PCD as follows using the Shell's PCD:
   EXAMPLE: to add the shell to Nt32 emulation, edit file "Nt32Pkg.dsc" add the following to the [PcdsFixedAtBuild] section
   gEfiIntelFrameworkModulePkgTokenSpaceGuid.PcdShellFile|{ 0x83, 0xA5, 0x04, 0x7C, 0x3E, 0x9E, 0x1C, 0x4F, 0xAD, 0x65, 0xE0, 0x52, 0x68, 0xD0, 0xB4, 0xD1 }

3. Remove the old shell from the Firmware list .fdf file.
   Remove the FILE APPLICATION section for the old shell.
   EXAMPLE: to add the shell to Nt32 emulation, edit file "Nt32Pkg.fdf" and comment out the following:
     #FILE APPLICATION = PCD(gEfiIntelFrameworkModulePkgTokenSpaceGuid.PcdShellFile) {
     #    SECTION PE32 = EdkShellBinPkg/FullShell/Ia32/Shell_Full.efi
     #  }

4. Add this shell to the .fdf firmware list
   Add the Shell.INF to the end of the list of DXE modules.
   EXAMPLE: to add the shell to Nt32 emulation, edit file "Nt32Pkg.fdf" add the following at the end of the DXE modules:

    INF  ShellPkg/Application/Shell/Shell.inf

5. Build -p Nt32Pkg\Nt32Pkg.dsc

KNOWN LIMITATIONS
1. RM can delete current working directory via other map name.
2. DrvCfg is not functional.
3. ifConfig permanent settings are under investigation (may not function correctly)
4. Shell documentation is in development and forthcoming.
