grab the following files and write them to an sdcard like this:

	; hget https://cdn.openbsd.org/pub/OpenBSD/7.4/arm64/install74.img >install74.img
	; hget http://spooky.computer/flash.bin >flash.bin
	; dd -bs 8m <install74.img >/your/sdcard
	; dd -bs 1k -seek 33 <flash.bin >/your/sdcard

•	Install the SD card in your reform (assuming you have the boot switch set to SD) and you should be presented with u-boot, which will boot into the OpenBSD bootloader. Interrupt the OpenBSD bootloader and type “set tty fb0”, then press enter to boot the installer.

•	Install OpenBSD as normal, you should be able to install to NVMe without issue. Full disk encryption also works, as well as unlocking the disk in the bootloader.

note: after booting the kernel i couldn't mount the sdcard image to install from, so had to use http install.

•	At the end of the install, don’t select reboot, instead choose shell. In the shell run echo "set tty fb0" > /mnt/etc/boot.conf to make sure the framebuffer console is used on boot

note: if you install more than one operating system on the nvme, openbsd's bootloader won't understand how to find your openbsd partition. you will need to interrupt it and provide the following:

	boot> set tty fb0	# bootloader didn't know where to find /etc/boot.conf
	boot> boot sr0a:/bsd	# if your installed is encrypted, point to the softraid device

caveats:

- some drivers (like iwn) are not included by default in the arm64 kernel.
