 Next, I plugged the Beelinks (one after another) into my monitor via HDMI (the resolution of the FreeBSD text console seems strangely stretched, as I am using the LG Dual Up monitor), connected Ethernet, an external USB keyboard, and the FreeBSD USB stick, and booted the devices up. With F7, I entered the boot menu and selected the USB stick for the FreeBSD installation.
