EOL_t420-maximized.config

# WARNING: This system remains perpetually vulnerable to Spectre v2 (CVE-2017-5715). Mitigations and microcode updates previously applied are now known to be ineffective due to QSB-107 and related CVEs. If Spectre v2 is a concern in your threat model, consider migrating to a platform with ongoing microcode support. Proper OPSEC for Memory Use MUST be followed:https://www.anarsec.guide/posts/qubes/#appendix-opsec-for-memory-use

# CAVEATS: TPM_GPIO_RESET=NOT_VULNERABLE -- dedicated PLTRST# pin, not shared with GPIO
# See doc/TPM_GPIO_Reset_Vulnerability.md for details.
# Configuration for a T420 running Qubes 4.1 and other Linux Based OSes (through kexec)
#
# Includes
# - Deactivated+neutered ME and expended consequent IFD BIOS regions
# - Forged 00:DE:AD:C0:FF:EE MAC address  (if not extracting gbe.bin from backup with blobs/xx20/extract.sh)
#   - Note that this MAC address can be modified under build/coreboot-VER/util/bincfg/gbe-82579LM.set
#
# Doesn't include (to fit in 7mb image)
# - dropbear
