Several 'Not supported' messages with UEFI boot

[Mike Clarke]

As an experiment I've switched from legacy boot to UEFI. It seems to be 
working OK except that I see several 'Not supported' messages at the start of 
the boot process.

I've manually typed the following boot messages from a video shot of the 
start up so there may be a few typos.

>> FreeBSD EFI boot block
   Loader path /boot/loader.efi

   Initializing modules: ZFS UFS
   Load Path: \EFI\BOOT\BOOTX64,EFI
   Load Device: PciRoot(0x0)/Pci(0x1f,0x2)/Sata(0x0,0x0)/HD(2,GPT,
62ea9e00-529a-11eb-94b8-408d5c843d74,0x428,0xbd8)
   BootCurrent: 002e
   BootOrder: 002e[*] 002d 0028 002a 0026 0017 0018 0016 0019 0029 002b

    UFS found no partitions

Things then scrolled too fast to capture a sharp video until the FreeBSD 
loader menu appeared and everything went normally.

So should I worry about the 'Not supported' messages, just ignore them or 
revert to legacy boot?
