-				It is also possible to generate a descriptor+gbe image with your own MAC address
+				Running ich9gen this way (without any arguments) generates
+				a default descriptor+gbe image with a generic MAC address.
+				You probably don't want to use the generic one; the ROM images
+				in libreboot contain a descriptor+gbe image by default (already
+				inserted) just to prevent or mitigate the risk of bricking
+				your laptop, but with the generic MAC address (the libreboot
+				project does not know what your real MAC address is).
+			</p>

+			<p>
+				On GM45 laptops that use flash descriptors, the MAC address
+				or the onboard ethernet chipset is flashed (inside the ROM image).
+				You should 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)
