heads/boards/w530-hotp-maximized/w530-hotp-maximized.config

# Configuration for a W530 running Qubes and other Linux Based OSes (through kexec)
#
# Includes 
# - Deactivated+neutered ME and expanded consequent IFD BIOS regions 
# - Forged 00:DE:AD:C0:FF:EE MAC address  (if not extracting gbe.bin from backup with blobs/xx30/extract.sh)
#   - Note that this MAC address can be modified under build/coreboot-VER/util/bincfg/gbe-82579LM.set
#
# - Includes Nitrokey/Librem Key HOTP Security dongle remote attestation (in addition to TOTP remote attestation through Qr Code)
# This board ignores the in-built dGPU that comes with all w530's. In doing so the dGPU will not be initialized. This has some benefits in terms of reduced complexity in working with OS's with poor support for NVIDIA, better battery life and lower heat (making use of the thicker heatsink from a dGPU). Conversely, if you do not initialize the dGPU you will be unable to use an external monitor. To initialize the dGPU please use the dGPU boards that corresponds with the model of dGPU included with your device.

# xx30-*-maximized boards require of you initially call one of the
#  following to have gbe.bin ifd.bin and me.bin
#  - blobs/xx30/download_clean_me.sh
#     To download Lenovo original ME binary, neuter+deactivate ME, produce
#      reduced IFD ME region and expanded BIOS IFD region.
#  - blobs/xx30/extract.sh
#     To extract from backuped 8M (bottom SPI) ME binary, GBE and IFD blobs.
#
# This board has two SPI flash chips, an 8 MB that holds the IFD,
# the ME image and part of the coreboot image, and a 4 MB one that
# has the rest of the coreboot and the reset vector.
#   
# As a consequence, this replaces the need of having to flash t530-flash 
#  and expands available CBFS region (11.5Mb available CBFS space)
#
# When flashing via an external programmer it is easiest to have
# two separate files for these pieces.
