Episode Details

Your Ubuntu server won't boot. Not just the OS — you can't even get a live USB to come up. The screen stays black, fans spin, and you're staring at a hardware problem with no software tools to diagnose it. This episode breaks down what's actually happening when your server crosses from "software crash" into "silicon failure," and how to diagnose it using tools you probably already have: the BMC's IPMI interface, serial-over-LAN consoles, and a $30 POST card. Learn why SystemRescue 11.02 can't save you when the memory controller won't train, how to read POST codes across Intel and AMD chipsets, and the systematic minimum-configuration method that stops you from firing the parts cannon at perfectly good hardware.
