I boot from a USB3 SSD that has:

# gpart show -p
=>       40  468862048    da0  GPT  (224G)
         40       2008         - free -  (1.0M)
       2048  413138944  da0p1  freebsd-ufs  (197G)
  413140992    9437184  da0p2  freebsd-swap  (4.5G)
  422578176     204800  da0p3  ms-basic-data  (100M)
  422782976   46079112         - free -  (22G)

The RPi4B finds start4.elf just fine.
