</ul> - -<hr/> - - <h1 id="why">What is libreboot, really?</h1> - - <h2> - Project goals (and differences versus coreboot): - </h2> - <ul> - <li> - Coreboot contains blobs (proprietary data/code) and libreboot does not (it intentionally removes them). - </li> - <li> - Coreboot is hacker-friendly and focuses on software developers, libreboot is user-focused and attempts to - turn coreboot into a distribution, sort of like a GNU/Linux distribution (same concept, different software). For example, libreboot - distributes GRUB/memtest86+/bucts/flashrom (and more) and comes with user-focused documentation and build scripts; libreboot - is therefore made more 'user-friendly'. - </li> - </ul> - - <p> - Libreboot is <b>not</b> a fork of coreboot, despite misconceptions of this fact. Libreboot (downstream supplier) is a parallel effort - which works closely with and re-bases on the latest coreboot (upstream supplier) every so often. - </p> - - <p> - <b> - As such, all new coreboot development should be done in coreboot, not libreboot! - Libreboot is about deblobbing, and packaging coreboot in a user-friendly way, where most work is already done for the user! - If, for example you wanted to attempt porting a new motherboard then you should do that in coreboot. Libreboot will (as a downstream) - receive your change at some point in the future, in a future release. - </b> - </p> - - <h2> - A 'stable' coreboot: - </h2> - <ul> - <li> - Coreboot uses the <a href="https://en.wikipedia.org/wiki/Rolling_release">rolling release</a> model - (and it is therefore quite volatile; one day when you build coreboot, it may or may not work correctly on your machine). - </li> - <li> - Libreboot changes less often (as far as the release model is concerned), focusing instead on 'tested' releases for <i>specific machines</i>. - At any given time, it might also be possible to build ROM images for systems other than those officially supported. If you get your board to work - (without violating the <i>"coreboot development goes in coreboot"</i> rule, then others could benefit from your work). - </li> - </ul> - - <p> - On the other hand, coreboot is also strict about what it accepts (merges) into the main git repository: - most of the time, a lot of changes are under review at review.coreboot.org (as a way of encouraging as much further development - as possible before accepting the patch). - </p> - - <p> - Meanwhile, libreboot is a lot less strict in this area and freely merges specific patches that are desirable, sometimes before they are merged into coreboot's main repository. - </p> - - <p><a href="#pagetop">Back to top of page.</a></p> - -<hr/> - - <h1 id="build_dependencies">Install build dependencies</h1> - - <p> - Before doing anything, you need the dependencies first. - </p> - <ul> - <li><b>deps-trisquel</b> script installs dependencies for Trisquel 6 (also tested in Trisquel 7).</li> - <li><b>deps-parabola</b> script installs dependencies for Parabola</li> - </ul> - - <p> - For all other GNU/Linux distributions, you may have to adapt these scripts.

The archive in the git repository used to be - available as a tarball called 'libreboot_meta.tar.gz'. It contains 'metadata' (scripts) - which define how the source was created (where it came from). - </p> - - <p> - You can use the scripts included to download everything. - </p> + <h1 id="pagetop">Documentation for libreboot project</h1> <p> - First, <a href="#build_dependencies">install the build dependencies</a>. + It is assumed that you are running <a href="https://www.gnu.org/distros/">GNU/Linux</a> + (no other operating system is known to work with this release). </p> - <p> - After that, run the get script:<br/> - <b>$ ./getall</b> + <a href="#why">What is libreboot?</a> </p> - <p> - What this did was download everything (grub, coreboot, memtest86+, bucts, flashrom) - at the versions last tested for this release, and patch them.

Lenovo BIOS will prevent you from writing the - final one, so running "<b>bucts 1</b>" will set the machine to boot from the other block instead (which - is writeable along with everything beneath it when using a patched flashrom. see <a href="#build_flashrom">#build_flashrom</a>). - After shutting down and booting up after the first flash, - the final 64K block is writeable so you flash the ROM again with an unpatched flashrom and run "<b>bucts 0</b>" to - make the machine boot from the normal (highest) block again. - </p> - - <p> - BUC.TS utility is included in libreboot_src.tar.gz and libreboot_bin.tar.gz.<br/> - <b>If you downloaded from git, follow <a href="#build_meta">#build_meta</a> before you proceed.</b> - </p> - - <p> - "BUC" means "<b>B</b>ack<b>u</b>p <b>C</b>ontrol" (it's a register) and "TS" means "<b>T</b>op <b>S</b>wap" - (it's a status bit).
