Seems I can't find any info about that on whole internet.
I try on BIOS module,opened in IDA,initial analyze is done.
Module is x64
Load file -parse C header file - behemoth.h
Compilation OK message.
View - open subviews - Local types
Select all synchronize to IDB
Here I get only errors "Failed to add constant"
like this
EFI_MEMORY_TYPE: failed to add constant EfiReservedMemoryType=0
What I do wrong?
