Recently, Gravis made one hell of a dive into the horrible abuse of the BIOS to make a bootleg hypervisor, and then went even deeper to find truly cursed usage of forbidden processor features. User DecayWTF had a few things to add to this, and I wanted to add on further, but... well, I didn't want to hijack the thread. I've been putting this off for far too long, and now I'm going to finally get around to doing something I said I was going to do a few months ago.

Welcome to the first installment of my article series called "Education Yourself". This series aims to highlight the weird, failed, obscure, and interesting aspects of computing and technology history, usually in an entertaining tone with a short-ish length. I might go kind of fast, but I do hope that you get a kick out of this, and learn something new along the way. So sit back, relax, and prepare to be horrified when I tell you that your modern Intel or AMD x86-64 CPU... is not x86-64.
