一、 修改UEFI UiApp源代码

1. 修改 FrontPageStrings.uni 与 FrontPageVfr.Vfr
   添加字符串资源到 MdeModulePkg/Application/UiApp/FrontPageStrings.uni

//Add CSDN UI resources #string STR_CSDN_BANNER_LEFT #language en-US "Csdn Bannder Left" #string STR_CSDN_BANNER_RIGHT #language en-US "Csdn Bannder Right" #string STR_CSDN_STRING #language en-US "CsdnText" #language fr-FR "CsdnText" #string STR_CSDN_STRING_HELP #language en-US "CsdnText the current setting." #language fr-FR "CsdnText the current setting." #string STR_CSDN_RADIO_STRING #language en-US "CsdnRdioBtn" #language fr-FR "CsdnRdioBtn" #string STR_CSDN_RADIO_STRING_HELP #language en-US "CsdnRadio the current setting." #language fr-FR "CsdnRadio the current setting." #string STR_CSDN_STRING_RADIO_1 #language en-US "Csdn Radio Button No 1" #string STR_CSDN_STRING_RADIO_2 #language en-US "Csdn Radio Button No 2" #string STR_CSDN_STRING_RADIO_3 #language en-US "Csdn Radio Button No 3" #string STR_CSDN_STRING_RADIO_4 #language en-US "Csdn Radio Button No 4" #string STR_CSDN_STRING_RADIO_5 #language en-US "Csdn Radio Button No 5" #string STR_CSDN_STRING_RADIO_6 #language en-US "Csdn Radio Button No 6" #string STR_CSDN_STRING_RADIO_7 #language en-US "Csdn Radio Button No 7" 

讯享网 banner title = STRING_TOKEN(STR_CSDN_BANNER_LEFT), line 4, align left; banner title = STRING_TOKEN(STR_CSDN_BANNER_RIGHT), line 4, align right; 

2. 修改 FrontPageCustomizedUi.c 与 FrontPageCustomizedUiSupport.c
   添加 Oneof（RadioButton） 菜单
   MdeModulePkg/Application/UiApp/FrontPageCustomizedUi.c

/ Customize menus in the page. @param[in] HiiHandle The HII Handle of the form to update. @param[in] StartOpCodeHandle The context used to insert opcode. @param[in] CustomizePageType The page type need to be customized. / VOID UiCustomizeFrontPage ( IN EFI_HII_HANDLE HiiHandle, IN VOID *StartOpCodeHandle ) { // // Create "Select CSDN" menu with Oneof opcode. // UiCreateCsdnRadioMenu(HiiHandle, StartOpCodeHandle); ... // // Create csdn menu. // UiCreateCsdnMenu(HiiHandle, StartOpCodeHandle); } 

MdeModulePkg/Application/UiApp/FrontPageCustomizedUiSupport.c

讯享网// 定义 CallBack EFI_STATUS CsdnRadioChangeHandler ( IN EFI_IFR_TYPE_VALUE *Value ) { EFI_STATUS Status; CHAR8 *CsdnText = "Csdn Radio Button No 1"; DEBUG((EFI_D_INFO,"[csdn] CsdnRadioChangeHandler value=%x\n",Value->u8)); Status = gRT->SetVariable ( L"CSDNRadioButtonText", &gEfiIfrFrontPageGuid, EFI_VARIABLE_NON_VOLATILE | EFI_VARIABLE_BOOTSERVICE_ACCESS | EFI_VARIABLE_RUNTIME_ACCESS, 22, CsdnText ); if (EFI_ERROR (Status)) { DEBUG((EFI_D_INFO,"[csdn] CsdnRadioChangeHandler status=%r\n",Status)); return EFI_DEVICE_ERROR; } return EFI_SUCCESS; } //触发 CallBack BOOLEAN UiSupportLibCallbackHandler ( IN EFI_HII_HANDLE HiiHandle, IN EFI_BROWSER_ACTION Action, IN EFI_QUESTION_ID QuestionId, IN UINT8 Type, IN EFI_IFR_TYPE_VALUE *Value, OUT EFI_BROWSER_ACTION_REQUEST *ActionRequest, OUT EFI_STATUS *Status ){ ... switch (QuestionId) { case FRONT_PAGE_KEY_CONTINUE: // // This is the continue - clear the screen and return an error to get out of FrontPage loop // *ActionRequest = EFI_BROWSER_ACTION_REQUEST_EXIT; break; ... //CallBack 触发入口 case FRONT_PAGE_KEY_CSDN_RADIIO: *Status = CsdnRadioChangeHandler(Value); break; default: break; } } 

二、 编译生成EFI文件

运行edksetup.bat && build -a X64 -p OvmfPkg\OvmfPkgX64.dsc -D DEBUG_ON_SERIAL_PORT -t VS2013x86编译整个OvmfPkg Package

三、 运行 UEFI

执行setup-qemu-x64.bat | findstr csdn
