The following is some quick notes on using CHIPSEC to compare the EFI whitelist on your current machine with the BIOS Dell provides
- Install prerequisites (Uses python 2)
- Git clone Chipsec
- Install (Had to use a -i option, is in the manual)
- Run (Use spaces like below)
Extract Bios ROM from Dell EXE
Use the BIOS exe to output a .rom file that you can use in Linux. Run the following command from Windows command prompt, accept the security request. Change the EXE to the BIOS you downloaded.
The BIOS rom is named dell.rom in the following commands
Get list of Computer ROM
Should create fw.bin file and efilist.json file from local machine
sudo python chipsec_main.py -m tools.uefi.whitelist
Get list from Dell rom
sudo python chipsec_main.py -m tools.uefi.whitelist -a generate efilist.json dell.rom
Compare the current ROM against the one downloaded from Dell
sudo python chipsec_main.py -m tools.uefi.whitelist -a check efilist.json fw.bin
For some reason Ubuntu was not recognizing the last three options after the -a as individual options unless there was a space in between them. All the examples online show that they had commas between them. Which should work, so wonder if it was an environment variable problem or something.
The tell tell sign was the [*] Module arguments Line only shows 1 argument, needs 3.
