<p>Hi all,</p>
<p>Recently I am working on <a
href="http://hardenedlinux.github.io/firmware/2016/11/17/neutralize_ME_firmware_on_sandybridge_and_ivybridge.html">neutralizing</a>
<a href="https://github.com/corna/me_cleaner/">ME</a> for various
platform whose ME cannot be completely removed. After I have
finished building coreboot for a ga-b75m-d3h board with its own ME
neutralized, I tried to use a neutralized version of Samsung
lumpy's ME (located at <code>3rdparty/blobs/mainboard/samsung/lumpy/me.bin,
which I have successfully applied to my Lenovo x220) on the
board, due to its smaller size.</code></p>
<p><code>This trial is mostly successful, except that the integrated
graphic card completely ceased to work and disappeared from the
PCI bridge, to my suprise. In such situation, a discrete graphic
card should be used instead.</code></p>
<p><code>It seems the </code><code>integrated graphic card is
dominated by ME, related to some Digital Restriction Management
schemes like PAVP or something.</code></p>
<p><code>On the other hand, in </code><code>situations where </code><code>discrete
graphic cards are feasible or headless usage, this scheme may be
useful, as more space is left for CBFS.</code></p>
