I can do some more testing later … 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. It is possible that the boot sequence to the UEFI USB key, and BIOS Hard Disk. I’m not sure you can say or detect that a BIOS is EFI only. Where BIOS+EFI support would work on both. This could be a valid setup … I’m playing/testing now (as I type) with the Radeon and Intel graphics with drm-*-kmod mode setting drivers … and currently in FreeBSD, thees drivers fail when a systems boots via EFI. So the EFI+BIOS is likely the “safe” option … until we can get some more intelligence around installations. This is mostly observed with X7,X8,X9,X10,X11 - series Supermicro boards with … uh … AMI BIOS(?). 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_at_freebsd.org> wrote: > > > > On 9/23/18 3:57 PM, David P.
