 # coreboot-x230
 pre-built coreboot images and documentation on how to flash them for the Thinkpad X230
+
+These imges:
+* include Lenovo's proprietary VGA BIOS ROM. If it might not be needed anymore, I'm happy for hints.
+* include [SeaBIOS](https://seabios.org/SeaBIOS) as coreboot payload, for maximum compatibility.
+* are meant to be [flashed externally](#how-to-flash)
+
+## Latest build
+See our [releases](https://github.com/merge/coreboot-x230/releases)
+
+## Flashing for the first time
+
+### EC firmware
+Enter Lenovo's BIOS with __F1__ and check the embedded controller (EC) version to be
+__1.14__ and upgrade using [the latest bootable CD](https://support.lenovo.com/at/en/downloads/ds029188)
+if it isn't. The EC cannot be upgraded when coreboot is installed. (In case a newer
+version should ever be available (I doubt it), you could temporarily flash back your
+original Lenovo BIOS image)
+
+### me_cleaner
+The Intel Management Engine resides on the 8MB chip. We don't need to touch it
+for coreboot-upgrades in the future, but while opening up the Thinkpad anyways,
+we can save it and run [ifdtool](https://github.com/coreboot/coreboot/tree/master/util/ifdtool)
+and [me_cleaner](https://github.com/corna/me_cleaner) on it:
+
+
+      flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=128 -c "MX25L3206E/MX25L3208E" -r ifdmegbe.rom
+      flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=128 -c "MX25L3206E/MX25L3208E" -r ifdmegbe2.rom
+      diff ifdmegbe.rom ifdmegbe2.rom
+      git clone https://github.com/corna/me_cleaner.git && cd me_cleaner
+      ./me_cleaner.py -O ifdmegbe_meclean.rom ifdmegbe.rom
+      ifdtool -u ifdmegbe_meclean.rom
+      flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=128 -c "MX25L3206E/MX25L3208E" -w ifdmegbe_meclean.rom.new
+
+### save the 4MB chip
+(internally, memory of the two chips is mapped together, the 8MB being the lower
+part, but we can essientially ignore that)
+
+For the first time, we have to save the original image, just like we did with
+the 8MB chip above:
+
+
+      flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=128 -r top1.rom
+      flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=128 -r top2.rom
+      diff top1.rom top2.rom
+
+## Flashing the coreboot / SeaBIOS image
+When __upgrading__ to a new version, for example when a new [SeaBIOS](https://seabios.org/Releases)
+version is available, only this has to be done.
+
+Download the latest release image we provide here and flash it:
+
+
+     flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=128 -w example.rom
+
+## How to flash
+We flash externally, using a "Pomona 5250 8-pin SOIC test clip". You'll find
+one easily.
+
+We connect it to a Raspberry Pi 3, running [Raspbian](https://www.raspberrypi.org/downloads/raspbian/)
+and the following setup
+* in the SD Cards's `/boot/config.txt` file `enable_uart=1` and `dtparam=spi=on`
+* [For flashrom](https://www.flashrom.org/RaspberryPi) we put `spi_bcm2835` and `spidev` in /etc/modules
+* [Connect to a wifi](https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md)
+* install `flashrom`
+* connect the Clip to the Raspberry Pi 3:
+
+		   Edge of pi (furthest from you)
+		 L                                                CS
+		 E                                                |
+		 F +---------------------------------------------------------------------------------+
+		 T |  x   x   x   x   x   x   x   x   x   x   x   x   x   x   x   x   x   x   x   x  |
+		   |  x   x   x   x   x   x   x   x   x   x   x   x   x   x   x   x   x   x   x   x  |
+		 E +----------------------------------^---^---^---^-------------------------------^--+
+		 D                                    |   |   |   |                               |
+		 G                                   3.3V MOSIMISO|                              GND
+		 E                                 (VCC)         CLK
+		   Body of Pi (closest to you)
+
+and you X230:
+
+
+		Screen (furthest from you)
+			     __
+		  MOSI  5 --|  |-- 4  GND
+		   CLK  6 --|  |-- 3  N/C
+		   N/C  7 --|  |-- 2  MISO
+		   VCC  8 --|__|-- 1  CS
+
+		   Edge (closest to you)
+
+
+Now you should be able to run the above mentioned `flashrom` commands.
+
+## How we build
+Everything necessary to build coreboot is included in this project and building
+coreboot is not hard at all. Please refer to [coreboot's own documentation](https://www.coreboot.org/Build_HOWTO).
+
+When building, testing and doing a release here, we always try to upload our
+result to coreboot's [board status project](https://www.coreboot.org/Supported_Motherboards).
