Another successful OpenBSD setup
I’ve been buying these little boxes from AliExpress for years to use as firewalls and routers. My oldest one is almost 9 years old now! OpenBSD installs just fine. Just a BIOS tweak to always boot up after power is restored.
Open source bios yes, but you still have close source firmware blobs for amd/intel used on those systems. The only way to do this is to make 100% of the hardware.
Also please note, I am using coreboot already on my pcengines router.
