Hi,

according to the wiki:

https://wiki.freebsd.org/UEFI#Tasks =
<https://wiki.freebsd.org/UEFI#Tasks>

it=E2=80=99s still unsolved and hasn=E2=80=99t even been started.


According to the status report:

The reason I=E2=80=99m 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 =E2=80=9EHBA mode=E2=80=9C  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...
