Yepp i dropped my jaw to. So if one don't pick UEFI boot in FreeNAS installation, it will never ever boot.
And of course i did what i always do an picked "legacy mode" in the installation.
The board have even more "funny" quirks. If you just power reset from iKVM it will not boot any type of iso or thumb drive. One need to power down and then power on again, then i boots the iso or thumb drive.
If you dont do that it will only loop boot menu screen. Screen goes black then you are right back in boot menu again.
*Still on BETA UEFI, and no news on when a stable one i going to be released.
