+ Usual limitations apply for native graphics initialization

+ There are two possible flash chip sizes for the R400: 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).

+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, gbe regions and how the ME was removed can be found in the notes linked at
+ <a href="../hcl/gm45_remove_me.html">../hcl/gm45_remove_me.html</a>. Libreboot ROM images now include
+ the 12KiB descriptor+gbe by default, generated using ich9gen;

+ inside your R400 ROM image, before flashing it.</b>
+ </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.
