+		to recover.
+	</p>
+	
+	<p>
+		The X200S is also briefly covered (image showing soldering joints, wired up
+		to a BBB). Note, the X200S and X200T are unsupported both in coreboot an libreboot at the time of writing (raminit doesn't work). This info

+	
+	<p>
+		Before following this section, please make sure to setup your libreboot ROM properly first. 
+		Although ROM images are provided pre-built in libreboot, there are some modifications that

+			There are two possible flash chip sizes for the X200: 4MiB
+			(32Mbit) or 8MiB (64Mbit). This can be identified by the type
+			of flash chip below the palmrest: 4MiB is SOIC-8 (8 pins), 8MiB
+			is SOIC-16 (16 pins). The X200S uses a WSON package and has the same
+			pinout as SOIC-8 (covered briefly later on in this guide) but
+			the chip is on the underside of the board (disassembly required).

+		<h2>Setting up the 3.3V DC PSU</h2>
+			<p>
+				With my PSU, first I had wire up the mains power cable. Any clover or kettle lead will do. Cut the end off (not the one
+				that goes in the wall, but the kettle/clover connector).
+				Strip the protection away by a decent length, then strip the wires inside so that a decent amount of
+				copper is shown. Then wire up earth/live/neutral. This will vary according to what country you live in
+				and/or the colour codes that your cable uses inside. <b>Make sure to get this right, as a botched job
+				could result in extreme damage to you and your surroundings. Here's what mine looks like after wiring up
+				the power cable: <a href="images/x200/psu_power.jpg">images/x200/psu_power.jpg</a> - also, make sure
+				that the plug (for the wall) has the correct fuse. In my case I had a 240V wall socket, and the device
+				says that it accepts 1.5A at that voltage, so I used the smallest fuse available (3A). For 110-120V the device
+				says it needs 2.8A.</b> Also, if yours looks like in the image linked above, make sure to wrap electrical tape (lots)
+				around it for safety. (otherwise, don't touch the terminals while the PSU is plugged in).
+			</p>
+			<p>
+				Now take a red and black 20cm female-female jumper lead, and cut one of the ends off. Strip away the bare copper by about 1 or
+				1.5cm so you get this: <a href="images/x200/stripped_jumper_lead.jpg">images/x200/stripped_jumper_lead.jpg</a>. 
+			</p>
+			<p>
+				Black goes on -V, red goes on +V. In my case, I removed those screws from my PSU like this:
+				<a href="images/x200/psu_screws_removed.jpg">images/x200/psu_screws_removed.jpg</a>. Then,
+			</p>
+			<p>
+				Then I twisted the exposed copper on the jumper leads (so that they don't fray), and wrapped each to one of the
+				screws each, around it near the head. I then screwed them in:
+				<a href="images/x200/psu_jumper_leads.jpg">images/x200/psu_jumper_leads.jpg</a>.
+			</p>
+			<p>
+				If you are using a different PSU, then the steps will change from those above. Anyway, once you are satisfied,
+				continue reading...
+			</p>
+		<h2>Setting up the BBB</h2>
+			<p>
+				Since it's a bare board (no case) and you are also touching inside your X200, you should be earthed/grounded. 
+				<a href="images/x200/strap.jpg">images/x200/strap.jpg</a> shows how I earthed myself. This is to prevent you 
+				from causing any ESD damage. The surface that you place components on should also be earthed/grounded.
+				(for this, I used a shielded ESD bag with a wire, copper exposed, attached from the bag to the exposed metal
+				part on a radiator, which was earthed - not professional, but it should work. see <a href="images/x200/mat.jpg">images/x200/mat.jpg</a>).
+				Most people ignore this advice and don't ground/earth themselves, at their own risk. You should also store the BBB
+				in a shielded anti-static bag when you are finished with it.
+				(the principles above apply to any computer components, since they are extremely sensitive te ESD).
+			</p>
+			<p>
+				These instructions may or may not work for you. They are simply the steps that this author took.
+			</p>
+			<p>
+				setting up SPIDEV on the BBB: <a href="http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0">http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0</a>
+				- If you only setup SPI0, you don't have to disable the HDMI out. (you only need one).
+				That guide is for seting up the device overlay for SPIDEV, last part is to make it persist across reboots.
+				Needed to turn the BBB into an SPI flasher.
+			</p>
+			<p>
+				Don't bother modifying uEnv.txt. it won't work;
+				use the workaround here instead: <a href="http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Loading_custom_capes">http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Loading_custom_capes</a>.
+			</p>
+			<p>
+				Follow the instructions at <a href="http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0">http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0</a>
+				up to (and excluding) the point where it tells you to modify uEnv.txt
+			</p>
+			<p>
+				You need to update the software on the BBB first. Before being able to use apt-get,
+				I had to use the workaround defined <a href="https://groups.google.com/forum/?_escaped_fragment_=msg/beagleboard/LPjCn4LEY2I/alozBGsbTJMJ#!msg/beagleboard/LPjCn4LEY2I/alozBGsbTJMJ">here</a>:<br/>

+ls: cannot access /dev/spidev0.*: No such file or directory

+			<p>
+				It didn't exist under that name, but I then did:<br/>

+			<p>
+				Now the BBB is ready to be used for flashing. Make this persist
+				across reboots:<br/>
+				In /etc/default/capemgr add <b>CAPE=BB-SPI0-01</b> at the end
+				(or change the existing <b>CAPE=</b> entry to say that, if an
+				entry already exists.
+			</p>
+			<p>
+				Now you will download and build <b>flashrom</b> on the BBB.<br/>
+				# <b>apt-get install libpci-dev pciutils zlib1g-dev libftdi-dev build-essential subversion</b><br/>

+Found Macronix flash chip &quot;MX25L6445E/MX25L6473E&quot; (8192 kB, SPI) on linux_spi.
+Multiple flash chip definitions match the detected chip(s): &quot;MX25L6405(D)&quot;, &quot;MX25L6406E/MX25L6436E&quot;, &quot;MX25L6445E/MX25L6473E&quot;
+Please specify which chip definition to use with the -c &lt;chipname&gt; option.
+</pre>
+			<p>
+				This is just to test that it's working. In my case, I had to define which chip to use, like so (in your case
+				it may be different, depending on what flash chip you have):<br/>
+				# <b>./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -c &quot;MX25L6405(D)&quot;</b>
+			</p>
+			<p>
+				At this point, you need to create a copy of the original lenovo firmware that is currently flashed. 
+				This is so that you can extract the gbe (gigabit ethernet) and flash descriptor regions for use in libreboot. <b>These
+				are not blobs, they only contain non-functional data (configuration details, fully readable) which is fully documented in public datasheets.</b>
+				The descriptor will need to be modified
+				to disable the ME (also disable AMT) so that you can flash a ROM that excludes it. 
+			</p>
+			<p>
+				How to backup factory.rom (change the -c option as neeed, for your flash chip):<br/>
+				# <b>./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -c &quot;MX25L6405(D)&quot; -r factory.rom</b><br/>
+				# <b>./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -c &quot;MX25L6405(D)&quot; -r factory1.rom</b><br/>
+				# <b>./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -c &quot;MX25L6405(D)&quot; -r factory2.rom</b><br/>
+				Now compare the 3 images:<br/>
+				# <b>sha512sum factory*.rom</b><br/>
+				If the hashes match, then just copy one of them (the factory.rom) to a safe place (on a drive connected to another machine, not
+				the BBB). You will need it later for part of the deblobbing.
+			</p>
+			<p>
+				Information about the descriptor and gbe can be found in the notes linked at
+				<a href="../hcl/x200_remove_me.html">../hcl/x200_remove_me.html</a> - also shows how to modify them to disable and remove the ME/AMT blob.
+				<span style="font-size:1.5em; background:#ccc;"><b><u><i>MAKE SURE TO FOLLOW THE GUIDE IN THIS LINK, BEFORE CONTINUING.
+				FAILURE TO DO SO WILL RESULT IN A BRICKED MACHINE.</i></u></b></span>
+			</p>
+			<p>
+				Assuming that your libreboot ROM image is properly setup (modified descriptor plus gbe region included in the ROM),
+				then you can flash (assuming that the filename is <b>libreboot.rom</b>) for example I had to do:<br/>
+				# <b>./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -c &quot;MX25L6405(D)&quot; -w libreboot.rom</b>
+			</p>
+			<p>
+				You might see errors, but if it says <b>Verifying flash... VERIFIED</b> at the end, then it's flashed and should boot.
+				Test it! (boot your X200)
+			</p>
+			<p>
+				My output when running the command above:
