Hello Stuart,
many thanks for your answer. Here in germany we have a phrase
"wer Lesen kann ist klar im Vorteil" -- you might benefit if you were
willing to read the instructions
I had not even known about acpi and device tree mode. I will read up

Oliver

Oh, did you leave it in acpi mode or switch to device tree? You'll

some files from https://github.com/raspberrypi/firmware/tree/next/boot
if it's in device tree mode.
From kettenis@:
"A workaround is to take the bcm2711-rpi-4-b.dtb, fixup4.dat and
start4.elf files from
https://github.com/raspberrypi/firmware/tree/next/boot
and put them on the MS-DOS partition of your uSD card."
