I am beginning to see why ARM is looked at as the future of computing. Also, I'm still waiting on ASUS to deploy the update for the motherboard! How do I light their arse on fire via Ethernet to get it done?!

I might be a little grumpy because the hernia's flaring up again. Goodie.

...Are you fucking kidding me?! Oh.. fucking hell!

And I didn't even touch on how downright cagey the manufacturers of ARM CPUs are. I dare you to try and find an actual datasheet for Qualcomm's latest ARM offerings! Now compare that to uh... Intel. Who doesn't even ask for an email address to download both books for the 13th/14th gen Core CPUs.

It's in the official datasheet, Errata: RP2350-E9, p.1340
The "fix" is either to do hacky software workarounds or "don't do this". Damned shame, this was looking to be an interesting and useful part! Though, most of them got used up for DEF CON:

Remember the incident that started all of *gesturing at above chosts* this nonsense? WELL,

We finally have an actual fix!



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.
