Sorry Berni, At this moment it isn't possible to install OpenBSD on the Raspberry Pi without a serial console. For that you need the Raspberry Pi Debug Probe: https://www.raspberrypi.com/documentation/microcontrollers/debug-probe.html Or an equvalent device. The only reasonable workaround is to install OpenBSD on a Raspberry Pi 3 or 4 and then move the SD card to the Raspberry Pi.
