=============================================================================
|
|||
|
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.

|
|||
|
|
|||

|
|||
|
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
|
|||
|
|

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<65> Atom<6F> 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.
