Hello everyone, I'm Rayray. I found my way here while searching for help with Libreboot/Coreboot. I'm working to get my third corebooted Thinkpad up and running. I've been tinkering with computers since I was in high school in the late 90's. I work in DevOps but spend a lot of free time messing with old computers and 8/16-bit game consoles.Comment
