Hi everyone
Thanks for the answer Mike.
I didn't find any file to include on my application that contains this
definition at UDK2010.
So I added this to my code:
#define SMBIOS_HANDLE_PI_RESERVED 0xFFFE
It didn't work yet.
Just to clarify the scenario, it's an UEFI application executed at UEFI
shell just to get some smbios information.
It's really similar to the smbiosview command. But I'm trying to use the
Smbios protocol as mentioned before.
Any other idea or point to check ?
Is there any hidden place where I can find this definition (I'm using
UDK2010) ?
Thanks everyone
