Hi Paul --

I don't have a board to try, but you should be able to boot NetBSD
on the 8GB model with the latest Pi4 UEFI firmware:


To use it, start with 'arm64.img' from NetBSD -current. Delete
everything from the MSDOS partition except for the "EFI" directory,
then place the contents of the RPi4 UEFI build on the root of the
SD card.

First time you boot, interrupt the UEFI firmware by pressing escape
and under the 'Advanced Configuration' find the "Limit RAM to 3 GB"
option and disable it.

Let us know how it goes!

Thanks for the easy-to-follow instructions!  I was able successfully
to boot my Raspberry Pi 4 8GB model using the above firmware and a
recent -CURRENT snapshot:

Does anyone know if HDMI output is supported on RPi4 or if it is only
serial console? Is there a way to tell from dmesg?

HDMI output and graphical console worked for me, but I only have one monitor.  I set the console preference to "Serial" but get output (and was able to input) on both.

I get these things in dmesg that appear related to console:
