Honestly, I got fed up with non-standard hardware having zero out-of-band management. I built a small KVM around a Radxa Zero 3W - it’s tiny enough to magnetically attach to the rack, so it doesn’t take up any shelf or desk space.
The “killer feature” is getting BIOS/UEFI output as terminal over SSH.
I keep the HDMI capture resolution at a fixed 800×600 for stability, but having the stream parsed into a terminal means I can finally grep or Ctrl+F through BIOS output, copy error logs, or even script the pre-OS stage.
It still handles the usual KVM tasks: USB HID emulation, video capture, remote ISO mounting, and even sharing network connectivity with the host when needed. I also added immutable snapshots for the data to keep a clean, tamper-resistant history of what happened before a crash.
It basically turns consumer-grade or "no-name" boards into something that feels a lot closer to enterprise hardware.
I’m curious - are there specific scenarios where searchable or scriptable BIOS output would be a game-changer for you, or is a standard video-only KVM "good enough" for most of your hardware?
