Hi, according to the wiki: https://wiki.freebsd.org/UEFI#Tasks <https://wiki.freebsd.org/UEFI#Tasks> it?s still unsolved and hasn?t even been started. According to the status report: https://www.freebsd.org/news/status/report-2015-04-2015-06.html#ZFS-Support-for-UEFI-Boot/Loader <https://www.freebsd.org/news/status/report-2015-04-2015-06.html#ZFS-Support-for-UEFI-Boot/Loader> some work has been done. https://lists.freebsd.org/pipermail/freebsd-hackers/2015-March/047486.html <https://lists.freebsd.org/pipermail/freebsd-hackers/2015-March/047486.html> The reason I?m asking is that all of our servers are HP DL 3[6|8]0 Gen9. These servers only support UEFI boot (you can set them to legacy-boot only for the next reboot). I would assume this to be true for more and more servers. I was playing with the idea of replacing the P440 controllers that we normally buy for these servers with the H240 controllers (these can be put into a so called ?HBA mode? and then present each disk directly, making them better suited for ZFS). However, the server still only boots with UEFI. And ZFS I want primarily to leverage beadm across all our servers...
