I boot from a USB3 SSD that has:
# gpart show -p
=3D> 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.
