Parabola theoretically supports it, by installing Arch first and then migrating to Parabola using the migration guide on the Parabola wiki, but it's not very well tested and does not have many packages - in our opinion, Parabola does not really support this laptop.

However, they run with a lot of free software at the boot software and embedded controller levels, since free software gives Google enough flexibility to optimize various aspects such as boot time and most importantly, to implement the CrOS security system, that involves various aspects of the software. Google does hire a lot of Coreboot developers, who are generally friendly to the free software movement and try to be good members of the free software community, by contributing code back. - -CrOS devices are designed (from the factory) to actually coax the user into using @uref{https://www.gnu.org/philosophy/who-does-that-server-really-serve.en.html,proprietary web services} (SaaSS) that invade the user's privacy (ChromeOS is literally just the Google Chrome browser when you boot up, itself proprietary and comes with proprietary add-ons like flash. It's only intended for SaaSS, not actual, real computing). Google is even a member of the @emph{PRISM} program, as outlined by Edward Snowden. See notes about ChromeOS below. The libreboot project recommends that the user replace the default @emph{ChromeOS} with a distribution that can be used in freedom, without invading the user's privacy. - -We also use a similar argument for the MacBook and the ThinkPads that are supported in libreboot.

The developer withheld it for personal reasons. Until that is released, the only way to use video (in freedom) on this laptop is to not have video acceleration, by making sure not to install the relevant blob. Most tasks can still be performed without video acceleration, without any noticeable performance penalty. - -In practise, this means that certain things like games, blender and GNOME shell (or other fancy desktops) won't work well. The libreboot project recommends a lightweight desktop which does not need video acceleration, such as @emph{XFCE} or @emph{LXDE}. - -The lima developer wrote this blog post, which sheds light on the story: @uref{http://libv.livejournal.com/27461.html,http://libv.livejournal.com/27461.html} - -@ref{#pagetop,Back to top of page}. - -@node Caution WiFi requires a non-free blob a USB dongle can be used instead -@chapter Caution: WiFi requires a non-free blob, a USB dongle can be used instead. -@anchor{#caution-wifi-requires-a-non-free-blob-a-usb-dongle-can-be-used-instead.} -These laptops have non-removeable (soldered on) WiFi chips, which require non-free firmware in the Linux kernel in order to work. - -The libreboot project recommends using an external USB wifi dongle that works with free software.

Google provides the source. Build scripts will be added later, with EC sources provided in libreboot, and builds of the EC firmware. - -This is unlike the other current libreboot laptops (Intel based). In practise, you can (if you do without the video/wifi blobs, and replace ChromeOS with a distribution that respects your freedom) be more free when using one of these laptops. - -The libreboot FAQ briefly describes what an @emph{EC} is: @uref{http://libreboot.org/faq/#firmware-ec,http://libreboot.org/faq/#firmware-ec} - -@node No microcode! -@chapter No microcode! -@anchor{#no-microcode} -Unlike x86 (e.g. Intel/AMD) CPUs, ARM CPUs do not use microcode, not even built in. On the Intel/AMD based libreboot systems, there is still microcode in the CPU (not considered problematic by the FSF, provided that it is reasonably trusted to not be malicious, since it's part of the hardware and read-only), but we exclude microcode updates (volatile updates which are uploaded at boot time by the boot firmware, if present), which are proprietary software. - -On ARM CPUs, the instruction set is implemented in circuitry, without microcode. - -@ref{#pagetop,Back to top of page}. - -@node Depthcharge payload -@chapter Depthcharge payload -@anchor{#depthcharge-payload} -These systems do not use the GRUB payload. Instead, they use a payload called depthcharge, which is common on CrOS devices. This is free software, maintained by Google. - -@node Flash chip write protection the screw -@chapter Flash chip write protection: the screw -@anchor{#flash-chip-write-protection-the-screw} -It's next to the flash chip. Unscrew it, and the flash chip is read-write. Screw it back in, and the flash chip is read-only. It's called the screw. - -@emph{The screw} is accessible by removing other screws and gently prying off the upper shell, where the flash chip and the screw are then directly accessible. User flashing from software is possible, without having to externally re-flash, but the flash chip is SPI (SOIC-8 form factor) so you can also externally re-flash if you want to. In practise, you only need to externally re-flash if you brick the laptop; read @uref{../install/bbb_setup.html,../install/bbb_setup.html} for an example of how to set up an SPI programmer. - -Write protection is useful, because it prevents the firmware from being re-flashed by any malicious software that might become executed on your GNU/Linux system, as root. In other words, it can prevent a firmware-level @emph{evil maid} attack. It's possible to write protect on all current libreboot systems, but CrOS devices make it easy. The screw is such a stupidly simple idea, which all designs should implement. - -Copyright © 2015 Leah Woods <info@@minifree.org>@* Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.

This was originally done on the ThinkPad X200, and later adapted for the ThinkPad R400/T400/T500. It can in principle be done on any GM45 or GS45 system. - -The ME is a blob that typically must be left inside the flash chip (in the ME region, as outlined by the default descriptor). On GM45, it is possible to remove it without any ill effects. All other parts of coreboot on GM45 systems (provided GMA MHD4500 / Intel graphics) can be blob-free, so removing the ME was the last obstacle to make GM45 a feasible target in libreboot (the systems can also work without the microcode blobs). - -The ME is removed and disabled in libreboot by modifying the descriptor. More info about this can be found in the ich9deblob/ich9gen source code in resources/utilities/ich9deblob/ in libreboot, or more generally on this page. - -More information about the ME can be found at @uref{http://www.coreboot.org/Intel_Management_Engine,http://www.coreboot.org/Intel_Management_Engine} and @uref{http://me.bios.io/Main_Page,http://me.bios.io/Main_Page}. - -Another project recently found: @uref{http://io.smashthestack.org/me/,http://io.smashthestack.org/me/} - -@uref{index.html,Back to previous index}. - -@node ICH9 gen utility -@chapter ICH9 gen utility -@anchor{#ich9-gen-utility} -It is no longer necessary to use @ref{#ich9deblob,ich9deblob} to generate a deblobbed descriptor+gbe image for GM45 targets. ich9gen is a small utility within ich9deblob that can generate them from scratch, without a factory.bin dump. - -ich9gen executables can be found under ./ich9deblob/ statically compiled in libreboot_util.

You probably don't want to use the generic one; the ROM images in libreboot contain a descriptor+gbe image by default (already inserted) just to prevent or mitigate the risk of bricking your laptop, but with the generic MAC address (the libreboot project does not know what your real MAC address is). - -You can find out your MAC address from @strong{ip addr} or @strong{ifconfig} in GNU/Linux. Alternatively, if you are running libreboot already (with the correct MAC address in your ROM), dump it (flashrom -r) and read the first 6 bytes from position 0x1000 (or 0x2000) in a hex editor (or, rename it to factory.rom and run it in ich9deblob: in the newly created mkgbe.c will be the individual bytes of your MAC address). If you are currently running the stock firmware and haven't installed libreboot yet, you can also run that through ich9deblob to get the mac address. - -An even simpler way to get the MAC address would be to read what's on the little sticker on the bottom/base of the laptop. - -On GM45 laptops that use flash descriptors, the MAC address or the onboard ethernet chipset is flashed (inside the ROM image). You should generate a descriptor+gbe image with your own MAC address inside (with the Gbe checksum updated to match).

With an unpatched coreboot, you get the following: @uref{../resources/text/x200s/cblog00.txt,x200s/cblog00.txt}. No SODIMM combination that was tested would work. At first glance, it looks like GS45 (chipset that X200S uses. X200 uses GM45) is unsupported, but there is a workaround that can be used to make certain models of the X200S work, depending on the RAM. - -The datasheet for GS45 describes two modes: low-performance and high-performance. Low performance uses the SU range of ultra-low voltage procesors (SU9400, for example), and high-performance uses the SL range of processors (SL9400, for example). According to datasheets, GS45 behaves very similarly to GM45 when operating in high-performance mode. - -The theory then was that you could simply remove the checks in coreboot and make it pass GS45 off as GM45; the idea is that, with a high-performance mode CPU (SL9400, for example) it would just boot up and work. - -This suspicion was confirmed with the following log: @uref{../resources/text/x200s/cblog01.txt,x200s/cblog01.txt}. The memory modules in this case are 2x4GB. @textstrikeout{@strong{However, not all configurations work: @uref{../resources/text/x200s/cblog02.txt,x200s/cblog02.txt} (2x2GB) and @uref{../resources/text/x200s/cblog03.txt,x200s/cblog03.txt} (1x2GB) show a failed bootup.}} @emph{False alarm. The modules were mixed (non-matching). X200S with high-performance mode CPU will work so long as you use matching memory modules (doesn't matter what size).} - -This was then pushed as a patch for coreboot, which can be found at @uref{http://review.coreboot.org/#/c/7786/,http://review.coreboot.org/#/c/7786/} (libreboot merges this patch in coreboot-libre now.

Alternatively, gs45 (if raminit is taken to be the only issue with it) can be part of gm45 northbridge support (and X200S/Tablet being part of the X200 port) with conditional checks in the raminit that make raminit work differently (as required) for GS45. nico_h and pgeorgi/patrickg in the coreboot IRC channel should know more about raminit on gm45 and likely gs45. - -pgeorgi recommends to run SerialICE on the factory BIOS (for X200S), comparing it with X200 (factory BIOS) and X200 (gm45 raminit code in coreboot), to see what the differences are.
