Deep dives into systems programming, infrastructure, security, and the craft of building reliable software. I write about the problems I'm solving and the tools I'm using.
Recently I found my desktop motherboard was vulnerable booting malicious payloads due to the use of a developer reference key in production firmware. I have a Gigabyte Aorus X570 Elite motherboard which is known to have a rather problematic UEFI BIOS.
Turning secure boot on, without the Microsoft keys present, would prevent any graphical output. The system was booting behind the scenes and I could SSH into it, only graphical output was affected. This is something that has been on my todo list for a while and was low priority enough I never got around to resolving it. This fresh news article gave me the drive to solve it.
If you have the same motherboard, you can recover from this issue by resetting the BIOS CMOS settings. You do have to physically remove the inconveniently located battery, as the jumper was ineffective. You also have to fully switch off or unplug your power supply during the removal.
