+			a deblobbed descriptor+gme image for the X200. ich9gen is a small utility within
+			ich9deblob that can generate them from scratch, without a factory.bin dump.

+		
+		<p>
+			Run:<br/>
+			$ <b>./ich9gen</b>

+				<li>ich9fdgbe_8m.bin: this is for X200 laptops with the 8MB flash chip.</li>
+			</ul>
+			
+		<p>
+			ich9gen executables can be found under ./ich9gen/ statically compiled in
+			libreboot_bin. If you are using src or git, build ich9gen from source with:<br/>
+			$ <b>./builddeps-ich9deblob</b><br/>
+			The executable will appear under resources/utilities/ich9deblob/
+		</p>
+		
+		<p>
+			Assuming that your X200 libreboot image is named <b>libreboot.rom</b>, copy
+			the file to where <b>libreboot.rom</b> is located
+			and then run, for instance:<br/>
+			$ <b>dd if=ich9fdgbe_8m.bin of=libreboot.rom bs=1 count=12k conv=notrunc</b><br/>
+			or:<br/>
+			$ <b>dd if=ich9fdgbe_4m.bin of=libreboot.rom bs=1 count=12k conv=notrunc</b>
+		</p>

+				<li>mkdescriptor.h</li>
+				<li>mkgbe.c</li>
+				<li>mkgbe.h</li>

+		<p>
+			These are C source files that can re-generate the very same Gbe and Descriptor structs
+			(from ich9deblob/ich9gen). To use these, place them in src/ich9gen/ in ich9deblob, then re-build. 
+			The newly built <b>ich9gen</b> executable will be able to re-create the very same 12KiB file from scratch,
+			based on the C structs, this time <b>without</b> the need for a factory.rom dump!
+		</p>

 			You should now have a <b>libreboot.rom</b> image containing the correct 4K descriptor and 8K gbe regions, which
 			will then be safe to flash. Refer back to <a href="../install/index.html#flashrom_x200">../install/index.html#flashrom_x200</a>
 			for how to flash it.
