I'd have thought so too, but the reading I did on this a while back (after discovering that booting to MBR-based internal hard drives was impossible on the newest computer models at my workplace) led me to statements that firmware writers can't support this anymore, because Intel's chipset implementation specifically does not let them do it. In practice, now that I research this again in depth, not only can I not find those statements again, all the reports of this behavior in the real world seem to be on Dell computers. I remember finding it stated that Dell had no choice in this because of what Intel had done, but I'm not finding those again now. I *do* find multiple statements that Intel is dropping all BIOS support from its UEFI firmwares (including, presumably, those it creates with / for its motherboard partners) by sometime in 2020, which has already passed; it's possible that that might include this behavior, but I'm not finding explicit statements of or reports about that just yet. https://arstechnica.com/gadgets/2017/11/intel-to-kill-off-the-last-vestiges-of-the-ancient-pc-bios-by-2020/ https://www.anandtech.com/show/12068/intel-to-remove-bios-support-from-uefi-by-2020 -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
