Building a Bootable USB drive with UEFI Shell (x64)

1. Format your media as FAT32

2. Create the following directory structure in the root of the new media

   • /efi/boot

3. Download the UEFI Shell (Shell.efi) from the following link

   • https://github.com/tianocore/edk2/blob/UDK2018/ShellBinPkg/UefiShell/X64/Shell.efi

4. Rename the UEFI shell file to Bootx64.efi

5. Copy the UEFI shell (now Bootx64.efi) to the /efi/boot directory

Installing CHIPSEC

1. Extract the contents of __install__/UEFI/chipsec_py368_uefi_x64.zip to the USB drive, as appropriate.

   • This will create a /efi/Tools directory with Python.efi and /efi/StdLib with subdirectories for dependencies.

2. Copy the contents of CHIPSEC to the USB drive.

   The contents of your drive should look like follows:

   -  fs0:
      -  efi
         -  boot
            -  bootx64.efi (optional)
         -  StdLib
            -  lib
               -  python36.8
                  -  [lots of python files and directories]
         -  Tools
            -  Python.efi
      -  chipsec
         -  chipsec
            -  …
         -  chipsec_main.py
         -  chipsec_util.py
         -  …
   

3. Reboot to the USB drive (this will boot to UEFI shell).

   • You may need to enable booting from USB in BIOS setup.

   • You will need to disable UEFI Secure Boot to boot to the UEFI Shell.

Run CHIPSEC in UEFI Shell

fs0:

cd chipsec

python.efi chipsec_main.py or python.efi chipsec_util.py

Next follow steps in section “Basic Usage” of Running CHIPSEC

Building UEFI Python 3.6.8 (optional)

1. Start with Py368Readme.txt

   • Latest EDK2, visit Tianocore EDK2 Github (Make sure to update submodules)

   • Latest EDK2-LIBC, visit Tianocore EDK2-LIBC Github

   • Follow setup steps described in the Py368Readme.txt

2. Make modifications as needed

   • CPython / C file(s):

     • edk2module.c

   • ASM file(s):

     • cpu.nasm

     • cpu_ia32.nasm

     • cpu_gcc.s

     • cpu_ia32_gcc.s

   • INF file(s):

     • Python368.inf

3. Build and directory creation steps are covered in the Py368Readme.txt

   • MSVS build tools are highly recommended
