I'm trying to get an installation of FreeBSD-12.1 / xen 4.12 running an Intel DQ67SW motherboard with 4 8TB disks attached to it up and running. Everything seems to work fine, except that the BIOS will not boot from the hard drives in legacy mode on its own. If I manually select a disk from the boot menu, FreeBSD and Xen load as they should. The Intel site says that booting from disks larger than 2TB is only supported if UEFI booting is enabled. It's my understanding that Freebsd-Xen will not run if one doesn't boot in legacy mode. Any suggestions on how to work around this conflict? Is it now possible to boot FreeBSD as Dom0 in UEFI boot mode? -thanks -Brian
