Also, I just tried to load the x86 version of bootmgfw.efi in a the IA32 Nt32Pkg shell. First I copied this file under edk2\Build\NT32IA32\DEBUG_VS2012x86\IA32. Then I ran the shell and then issued the command "load bootmgfw.efi". This failed with the error "Image is not a driver". This obviously means that the "load" command loads only drivers. How do I load an EFI application in this shell then?
