#2Hopefully we can get a fully libre boot on purism laptops soon.
I feel like there would be legal problems though...

What kind of legal problems would you anticipate?

Respectfully, why would they? The goal here is to find exploits in ME and use them to make Intel chips more end-user friendly.
When we were rooting Android devices we sat on a lot of exploits that we believed we could use to give end-users freedom. There were a handful that were bad enough to warrant disclosure [1], but we still offered them as ways for users to control their own devices with a few layers of obfuscation on top.

Publishing a blog post isn't exactly sitting on a vuln. I would understand if they kept it to themselves and I would understand if they reported to Intel, but this?

#9Meanwhile I'm trying to find a way to remove the hard lock on CPU and RAM frequencies (extreme CPUs can't be overclocked, RAM is locked at 1333 MHz) :)
Looks like it can be done through Management Engine, which has access to everything apparently.
Only success so far is unlocking BCLK, but the overclock is small and unstable that way.
Another roadblock was the read only lock, which can fortunately be bypassed on POST on xx67/77 chipsets.

e_context? but good luck anyway.
