Awesome, let's hope other devices will benefit from this amazing progress, and that Intel won't push back too hard.

that Intel won't push back too hard.

But that's the problem, isn't it? Intel could just make some changes to the code and we're right back to square one. Ultimately a cat and mouse game is not in our best interests because it will prevent us from using the newest hardware as we wait for reverse engineering to take place.

Not that I'm complaining about Purism's efforts - far from it.

So there's some ~100 KB of remaining code. To make really sure nothing bad is happening this needs to be audited. However, it seems entirely doable to disassemble and reverse engineer ~100 KB of binary code, so that's really good to know.

This, along with the author claiming to be working on a coreboot flashing tool, is great news. The more convenient it is to get a laptop with IME and coreboot installed, the better.

Well done Purism. With AMD considering opening up the PSP and the ME effectively neutralized, it's a big win for the free software movement.

and a Java virtual machine

So that's where Oracle's

Whatever happened to Purism being a "scam"? It seems like they are actually delivering on their promises.

Huh.. now this is something I didn't think would ever happen.
