.. _heads: Heads ===== Heads is secure BIOS replacement that provides tamper-evident features to detect when the BIOS or important boot files have been modified. The official project page can be found at `the official Heads GitHub page `_ and we base our Heads BIOS off of this code. On Purism laptops Heads is built as an executable on top of the same `coreboot BIOS `_ that we have used in the past but instead of coreboot running SeaBIOS to detect and boot into your devices, coreboot runs Heads instead. Current Status -------------- Currently Heads is available as part of an open Beta program and while this documentation will describe how to build, install, and use Heads on Librem hardware, it is still a complicated process intended for more technical users and involves manually flashing a BIOS. We have created a community Matrix channel for Heads users at #community-heads:talk.puri.sm. .. toctree:: Heads/User_Manual Heads/Report_an_Issue
