+## n00bie guide for getting [[coreboot|http://www.coreboot.org/Welcome_to_coreboot]] to a x201{i/s/t}
+
+###why would I want this?
+- prevent [[badBIOS|https://www.schneier.com/blog/archives/2013/11/badbios.html]]
+- free open source BIOS / EFI implementation
+- fast (faster than Lenovo BIOS)
+- no PCI ID whitelist restrictions (WiFi / WWAN)
+- you can boot even with SATA-password set (for example to change/delete it with hdparm)
+- hotswap harddrive (didn't test, but should work)
+- it's cool.
+
+###okay, show me how!
+#### preliminary actions
+first you should update your existing BIOS. This is important as you cannot update your [[ECP|http://www.thinkwiki.org/wiki/Embedded_Controller_Firmware]] version afterwards. Linux users can use the ISO files provided by Lenovo and do some nice trick described [[here|http://www.thinkwiki.org/wiki/BIOS_update_without_optical_disk]]
+
+It is also advisable to save the output of dmidecode somewhere, as you need specific BIOS versions strings to get thinkpad_acpi to work.
+
+next buy or build a SPI flasher and get a SOIC8 clip for mounting the chip correctly.
+
+#### the ugly part
+you have to dump the existing BIOS using [[flashrom|http://www.flashrom.org]] and an external SPI flasher.
+here's the pinout:
+[[!format bash """
+  ====  front (display) =====
+3.3V     N/C      CLK      MOSI
+ |        |        |        |
+ |        |        |        |
+CS       MISO     N/C      ground
+  ====  back (touchpad) =====
+"""]]
+
+[[!img bus_pirate.jpg align="right" size="" alt="buspirate attached"]]
+Now it should look similar to this:
+
+You probably have to adjust your contacts quite often for it to work, so don't give up ;) try to keep the cables as short as possible.
+
+
+now read your chip at least twice with
+
+[[!format bash """
+flashrom -p <yourprogrammer> -r flash.bin
+flashrom -p <yourprogrammer> -r flash2.bin
+diff flash.bin flash2.bin
+"""]]
+
+If the files differ you have read errors
+-> bad: check your cables && try again.
+
+#### easy part
+- extract descriptor / intel ME
+[[!format bash """
+dd if=flash.bin of=coreboot/3rdparty/mainboard/lenovo/x201/descriptor.bin \
+   count=12288 bs=1M iflag=count_bytes
+dd if=flash.bin of=coreboot/3rdparty/mainboard/lenovo/x201/me.bin \
+   skip=12288 count=5230592 bs=1M iflag=count_bytes,skip_bytes
+"""]]
+- extract vgabios.bin from BIOS (I used [[PhoenixTool|http://forums.mydigitallife.info/threads/13194-Tool-to-Insert-Replace-SLIC-in-Phoenix-Insyde-Dell-EFI-BIOSes]] in a WinBitch VM for this, as the included bios extractor from coreboot didn't work for me) 
+- hint [[SWIM|http://www.urbandictionary.com/define.php?term=swim]] [[uploaded|http://www.datafilehost.com/d/4c01e3d8]] [[it|http://rghost.net/55012997]] [[somewhere|http://fbx.ro/sseikovp02nh3ds2]] in the internets
+- use your prior version number for local version string (e.g [["6QET70WW (1.40)"|http://www.thinkwiki.org/wiki/List_of_DMI_IDs]])
+- at least UNCHECK fake IFD and specify paths to descriptor / ME
+- select SeaBIOS as payload
+- DO NOT FORGET vgabios.bin
+- [[compile coreboot|http://www.coreboot.org/Build_HOWTO]] (you'll need gcc-multilib and your python bin should point to python2, else create a venv)
+- flash resulting ROM image with
+[[!format bash """ 
+flashrom -c $Chip -w coreboot/build/coreboot.rom -p internal:laptop=force_I_want_a_brick """]]
