The +[EC firmware](../../faq.md#ec-embedded-controller-firmware) is separate from +libreboot, so we don't actually provide that, but if you still have +Lenovo BIOS then you can just run the Lenovo BIOS update utility, which +will update both the BIOS and EC version. See: + +- [../install/#flashrom](../install/#flashrom) +- <http://www.thinkwiki.org/wiki/BIOS_update_without_optical_disk> +- [X200, X200s, X200si BIOS Update](http://pcsupport.lenovo.com/au/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x200/downloads/ds015007) +- [X200t BIOS Update](http://pcsupport.lenovo.com/au/en/products/laptops-and-netbooks/thinkpad-x-series-tablet-laptops/thinkpad-x200-tablet/downloads/ds018814) + +NOTE: this can only be done when you are using Lenovo BIOS. How to +update the EC firmware while running libreboot is unknown. Libreboot +only replaces the BIOS firmware, not EC. + +Updated EC firmware has several advantages e.g. better battery +handling. + +Battery Recall {#batteryrecall} +========= +[On 21 April 2015, Lenovo expanded a recall on Lenovo batteries found in some ThinkPad models, which includes the X200 and X200S.](https://pcsupport.lenovo.com/cr/en/solutions/hf004122) +To find out if you are affected, use [this Lenovo tool.](https://lenovobattery2014.orderz.com/) +Lenovo advises that owners of the recalled models "should turn off the system, remove the battery, +and only power your ThinkPad by plugging in the AC adapter and power cord." +Upon battery verification, Lenovo will replace recalled batteries free of charge. +Battery replacement instructions for the X200/X200s are found [on this page.](https://pcsupport.lenovo.com/cr/en/parts/pd003507/) + +Compatibility (without blobs) {#compatibility_noblobs} +----------------------------- + +### Hardware virtualization (vt-x) {#hwvirt} + +The X200, when run without CPU microcode updates in coreboot, currently +kernel panics if running QEMU with vt-x enabled on 2 cores for the +guest. With a single core enabled for the guest, the guest panics (but +the host is fine). Working around this in QEMU might be possible; if +not, software virtualization should work fine (it's just slower). + +On GM45 hardware (with libreboot), make sure that the *kvm* and +*kvm\_intel* kernel modules are not loaded, when using QEMU. + +The following errata datasheet from Intel might help with investigation: +<http://download.intel.com/design/mobile/specupdt/320121.pdf> + +Anecdotal reports from at least 1 user suggests that some models with +CPU microcode 1067a (on the CPU itself) might work with vt-x in +libreboot. + +X200S and X200 Tablet. {#x200s} +---------------------- + +X200S and X200 Tablet have raminit issues at the time of writing (GS45 +chipset. X200 uses GM45). + +X200S and X200 Tablet are known to work, but only with certain CPU+RAM +configurations. The current stumbling block is RCOMP and SFF, mentioned +in <https://www.cs.cmu.edu/~410/doc/minimal_boot.pdf>. + +The issues mostly relate to raminit (memory initialization). With an +unpatched coreboot, you get the following: +[text/x200s/cblog00.txt](text/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: +[text/x200s/cblog01.txt](text/x200s/cblog01.txt). The memory modules in +this case are 2x4GB. ~~*However, not all configurations work: +[text/x200s/cblog02.txt](text/x200s/cblog02.txt) (2x2GB) and +[text/x200s/cblog03.txt](text/x200s/cblog03.txt) (1x2GB) show a failed +bootup.*~~ *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 +<http://review.coreboot.org/#/c/7786/> (libreboot merges this patch in +coreboot-libre now. Check the 'getcb' script in src or git). + +### Proper GS45 raminit {#x200s_raminit} + +A new northbridge gs45 should be added to coreboot, based on gm45, and a +new port x200st (X200S and X200T) should be added based on the x200 +port. + +This port would have proper raminit. 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. Then tweak raminit code +based on that. + +LCD compatibility list {#lcd_supported_list} +---------------------- + +LCD panel list (X200 panels listed there): +<http://www.thinkwiki.org/wiki/TFT_display> + +All LCD panels for the X200, X200S and X200 Tablet are known to work. + +The X200 Tablet has a screen rotation button on its bezel. Depending +on the operating system it might or might not rotate the screen, the +digitizer (stylus), or the trackpoint accordingly. Utilities are +provided to fix this at *resources/utilities/x200t-screen-rotation* in +the libreboot git repository. + +### AFFS/IPS panels {#ips} + +#### X200 + +Adapted from +<https://github.com/bibanon/Coreboot-ThinkPads/wiki/ThinkPad-X200> + +Look at wikipedia for difference between TN and IPS panels. IPS have +much better colour/contrast than a regular TN, and will typically have +good viewing angles. + +These seem to be from the X200 tablet. You need to find one without the +glass touchscreen protection on it (might be able to remove it, though). +It also must not have a digitizer on it (again, might be possible to +just simply remove the digitizer). + +- BOE-Hydis HV121WX4-120, HV121WX4-110 or HV121WX4-100 - cheap-ish, + might be hard to find + +- Samsung LTN121AP02-001 - common to find, cheap + +*If your X200 has an LED backlit panel in it, then you also need to get +an inverter and harness cable that is compatible with the CCFL panels. +To see which panel type you have, see +[\#led\_howtotell](#led_howtotell).

You need to replace the whole lid with +one from a normal X200/X201. + +How to tell if it has an LED or CCFL? {#led_howtotell} +------------------------------------- + +Some X200s have a CCFL backlight and some have an LED backlight, in their LCD +panel. This also means that the inverters will vary, so you must be careful if +ever replacing either the panel and/or inverter. (a CCFL inverter is +high-voltage and will destroy an LED backlit panel). + +CCFLs contain mercury. An X200 with a CCFL backlight will (unless it has been +changed to an LED, with the correct inverter. Check with your supplier!) say +the following: *"This product contains Lithium Ion Battery, Lithium Battery and +a lamp which contains mercury; dispose according to local, state or federal +laws"* (one with an LED backlit panel will say something different). + +Hardware register dumps {#regdumps} +----------------------- + +The coreboot wiki +[shows](http://www.coreboot.org/Motherboard_Porting_Guide) how to +collect various logs useful in porting to new boards.
