I downloaded the bootonly iso for FreeBSD 13 and it boots up, but there's no network interface found. The ARM Parallels doesn't have a selector for picking a card to emulate, and what I see on pciconf -l is a 1ab8 4000. I tried loading all of the available if_*.ko modules for it, but none of them appeared to match. I take it this means that I have to install from a proper image (that has everything the installer needs) and then install a driver for it after (Parallels tools for FreeBSD?), right?
I managed to fetch the distfile for parallels-tools 0.1.2, which matches what is in the default ports tree. I was able to build it, but attempting to load it results in this.
I tried a version 14 snapshot and it has a working network interface driver. I guess I'll have to wait for 13.1 for stable branch support.
