I can do some more testing later =E2=80=A6 but my observation is that a = system booted via EFI, the installer will auto select EFI+BIOS. If the = systems boots BIOS, it selects BIOS only.=20 It is possible that the boot sequence to the UEFI USB key, and BIOS Hard = Disk. I=E2=80=99m not sure you can say or detect that a BIOS is EFI = only. Where BIOS+EFI support would work on both.=20 This could be a valid setup =E2=80=A6 I=E2=80=99m playing/testing now = (as I type) with the Radeon and Intel graphics with drm-*-kmod mode = setting drivers =E2=80=A6 and currently in FreeBSD, thees drivers fail = when a systems boots via EFI. So the EFI+BIOS is likely the =E2=80=9Csaf= e=E2=80=9D option =E2=80=A6 until we can get some more intelligence = around installations. This is mostly observed with X7,X8,X9,X10,X11 - series Supermicro boards = with =E2=80=A6 uh =E2=80=A6 AMI BIOS(?).=20 Not clear if their is a smbios key set to indicate that the BIOS is = configured to EFI only. -dpd > On Sep 23, 2018, at 2:58 PM, Sean Bruno <sbruno@freebsd.org> wrote: >=20 >=20 >=20 > On 9/23/18 3:57 PM, David P.
