Librem 14 Features BIOS and EC Write Protection [3] We have been focused on BIOS security at Purism since the beginning, starting with our initiative to replace the proprietary BIOS on our first generation laptops with the open source coreboot project. This was a great first step as it not only meant customers could avoid proprietary code in line with Purism?s social purpose, it also meant the BIOS on Purism laptops could be audited for security bugs and possible backdoors to help avoid problems like the privilege escalation bug in Lenovo?s AMI firmware. Our next goal in BIOS security was to eliminate, replace or otherwise bypass the proprietary Intel Management Engine (ME) in our firmware. We have made massive progress on this front and our Librem laptops, Librem Mini, and Librem Server all ship with an ME that?s been disabled and neutralized. After that we shifted focus to protecting the BIOS against tampering.
