<p>
+ It is also possible to generate a descriptor+gbe image with your own MAC address
+ inside (with the Gbe checksum updated to match). Run:<br/>
+ $ <b>./ich9gen --macaddress XX:XX:XX:XX:XX:XX</b><br/>
+ (replace the XX chars with the hexadecimal chars in the MAC address that you want)
+ </p>
+
+ <p>
+ You can find out your MAC address from <b>ip addr</b> or <b>ifconfig</b> in GNU/Linux.
+ Alternatively, if you are running libreboot already (with the correct MAC address in your
+ ROM), dump it (flashrom -r) and read the first 6 bytes from position 0x1000 (or 0x2000) in a hex editor
+ (or, rename it to factory.rom and run it in ich9deblob: in the newly created mkgbe.c
+ will be the individual bytes of your MAC address). If you are currently running the stock firmware
+ and haven't installed libreboot yet, you can also run that through ich9deblob to get the mac address.
+ </p>
+
+ <p>
+ An even simpler way to get the MAC address would be to read what's on the little sticker on
+ the underside. (on the X200, this would be near the VGA port).
