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.
Few computers use CoreBoot, and CoreBoot still uses proprietary blobs typically. Normally only libreboot has zero blobs, and they are very rare indeed.
