All Haswell notebooks with NV (normal voltage) CPUs don't have Boot Guard, as BG was not yet supported by the ME firmware (version 9.0 or 9.1) that came with NV Haswell CPUs.

For ULV (ultra-low voltage) Haswell CPUs (whose models end with U or Y), the ME firmware (version 9.5) supports Boot Guard. However, BG was not enabled on some ULV notebook models (e.g. Lenovo ThinkPad (S1) Yoga and Dell Latitude E7240).

(Our community members and) I plan to maintain a whitelist (without BG) and a blacklist (with BG) for free/libre firmware users.
