Hi, For the installation procedure here https://ftp.openbsd.org/pub/OpenBSD/snapshots/arm64/INSTALL.arm64 is it possible to add that we can already install even without the serial console via TTL serial interface adapter (CP2102 USB-UART converter) because as tested I can install using my monitor and USB keyboard now in my Raspberry Pi 4B provided that upon installation you should type "set tty fb0" during boot-up and the UEFI config.txt file should have this line "hdmi_safe=1" in order to have display in the screen (see posted screenshots).
