Re: How to retrieve HII form's default value

["Gao, Liming" <liming.gao@intel.com>]

FCE supports Linux also. 

There is no MACRO to describe VFR default value as PCD value in DSC file. 
MdeModulePkg HiiLib has one function HiiSetToDefaults() to retrieve the default setting and set it at boot time. Its first parameter is ConfigRequestHdr that represents one varstore or efi varstore defined in VFR. You can see this function usage in MdeModulePkg\Universal\DriverSampleDxe\DriverSample.c

Thanks
