2. Build Guide
=============================================================================
3.1. Setup Build Environment
   1) Install Visual Studio 2005 or Visual Studio .NET 2003 in your build machine.
 
3.2. Extract the Files 

   1)  Building this driver is same with build other UEFI driver.
       - Download the extract EDK 1.06 package to a folder, for example C:\Framework
	Link for EDK 1.06 package:
            http://sourceforge.net/projects/efidevkit/files/Releases/Official%20Releases/Edk%201.06.zip/download
   2)  Extract the GOP driver to a package folder, for example C:\Framework\Edk\Sample\Universal\GOP.
   3)  Update the build descript file "platfrom.dsc" (e.g. C:\Framewrok\Edk\Sample\Platform\Nt32\Build\nt32.dsc) , 
            add the GOP build item. for example "Sample\Universal\Gop\Dxe\GOP.inf" in the components section
            of the nt32.dsc file.

       
3.3. Build Steps 
   1) Open Visual Studio 2005 Command Prompt, Change the work directory to build directory.
      For example, "cd C:\Framework\Edk\Sample\Platform\Nt32\" 
      and "set EDK_SOURCE=C:\Framework\Edk".
   2) Check <EFI_SOURCE>\Edk\Sample\Platform\Nt32\Build\Config.env: 
      - Set "USE_VC8 = YES" for Visual Studio 2005 build.
      - Set "USE_VC8 = NO" for Visual Studio .NET 2003 build.
   3) Type "Build" at the command prompt
      

   Note: To build this driver, please refer to the "EDK Getting Started Guide.pdf" found on the following link:
       http://sourceforge.net/projects/efidevkit/files/Edk%20Getting%20Started%20Guide%5B1%5D.0.41.pdf/download

4. Notes and Known Issues
============================================================================
 
    1) Video card is platform related. Each video card has its own config method. This sample 
       driver is developed for the Intel® Atom™ Platform. It may not work 
       on other platforms. Developer may need make necessory update for other platforms.
    
    2) This GOP Driver is support 3 resolutions. If the display device is not support these 
       resolutions. The display devices maybe not work correctly when switch to unsupported resolution.
      
    3) The GOP driver is a UEFI driver, so it should be built in UEFI environment. If building in EFI environment, it will be failed.
