CPU/hardware backdoors, coming up with solutions .... Anonymous 06/26/2021 (Sat) 11:09:26 [Preview] No. 14763
usually, it would require to externally/internally flash a libreboot bios and/or remove Intel ME with me_cleaner then install a fully free system such as parabola, so in this way the CIA can't glow on that computer.

fsf's ryf approved notebooks meet the requirements of freedom in hardware. sadly those resources aren't so accessible.. buying a ThinkPad made before intel ME and internally flashing libreboot (specifically X60) seems to be the easiest way to replicate what fsf did. in which sadly I couldn't find any X60 out there.

RISC-V powered computers are also an alternative, though I don't know any computer/notebook that has a RISC-V CPU .

ARM powered computers such as raspberry pi 4 seems to be a safe alternative since I haven't seen anyone whistleblowing about backdoors nor spyware on their hardware nor software, is it safe though ? what are your thoughts on this matter ?

Easier to destroy the radio towers.

ive been thinking on building a raspberry machine for some time now.

i personally like the idea of having like a sort of motherboard for multiple computing modules since the rpi foundation released their modules. this would make it possible to have a powerful computer in a fist-size box

the only thing stopping me from doing that is that theres is still no commercial solution for powering the machine from 18650 batteries, if someone could come up with a scalable solution to this i would definetely give it a try. and here i mean complete and efficient power management like charging and also an input for power from ac outlets.

would you care to explain what intel me is?
is it the new secure boot method that comes preinstalled on the board chips?
excuse my ignorance on this subject

I'm sure this video and fsf explains better than me

This shit has been around longer than Intel Management Engine. Intel AMT was in vPro product lines of the Core2 era. Mainly found in laptops, but also likely in the mainboards of business oriented workstations.
This is from 2007:

a riscv computer, hardware completely 100% open source, though is it also free? suppose it's even better than those thinkpads, since now there is hardware source code, we can just see and change what we don't like and do anything, effectively putting an end to surveillance.

If there's a hardware backdoor you will struggle to remove it. You can remove entire components - rip out camera, take out unnecessary wifi card - but there's always a trade off. If you're just using FB and crap, and don't mind the performance hit, go for it.

It's a step in the right direction, but you're still limited to the foundries. The foundries will know that the chips are going to be RISCV CPUs and can tweak them. The only way I can see to avoid the issue is to use FPGAs, since the foundry will not know the end use. Cost will become an issue, if attempting to use large FPGAs for CPUs.

Oldschool boomers have talked of this, watching as more and more integration led to obfuscated construction. What used to be daughter boards and discrete components, became small black ICs, and then those became fewer and fewer. Now there are SoC and things like Apple M1, the momentum is obvious. Intel moving what used to be the North Bridge into the actual CPU, this is also when Intel introduced the Management Engine.

couldn't anon just run TAILS OS on it and call it a day? Or are you trying to card from the workstation mentioned?
