Hi,

I`m also working on pi4  a little while not ready…
I recommend to switch the whole RPI-thing  to UEFI/ ACPI, J.McNeill is working on that , afaik…
So next step I see  is to implement ACPI-xhci-driver since FreeBSD-boot PANICS on xhci-
The good news is that I first saw USB working in UEFI-boot...…the ethernet driver should then later correspond or to be integrated into UEFI … nice to boot from a „Bios“ -style menu with a plugged USB-keyboard...

Regards

Klaus
