I’m a dinosaur from the pre-UEFI era, all I know is “BIOS boot". How do I find that out? What I can say is that when installing 9.3 I booted from the NetBSD-9.3-amd64-install.img and I did not choose to install on the “EFI system” (as I didn’t understand the “dk0@ld0” notation) but instead on the only disk presented, which was ld0. Then I choose GPT as the partitioning scheme. If the question of BIOS vs UEFI in practice equals MBR portioning vs GPT then this is now an UEFI-system. But if BIOS/UEFI vs MBR/GPT are orthogonal things then I simply don’t know. > Background is that I recently also tried to boot with Xen 4.15 on a UEFI-only > system (NetBSD 10.0_BETA) and exactly the same problem that I still get the > messages from Xen displayed, but then the NetBSD kernel does not start.
