+        <p>Recently I wanted to upgrade the firmware of my thinkpad, and
+located the firmware download page from Lenovo (which annoyingly do
+not allow access via Tor, forcing me to hand them more personal
+information that I would like).  The
+<a href="https://support.lenovo.com/us/en/solutions/ht003029-lenovo-system-update-update-drivers-bios-and-applications">download
+from Lenovo</a> is a bootable ISO image, which is a bit of a problem
+when all I got available is a USB memory stick.  I tried booting the
+ISO as a USB stick, but this did not work.  But genisoimage came to
+the rescue.</p>
+
+<P>The geteltorito program in
+<a href="http://tracker.debian.org/genisoimage">the genisoimage
+package</a> is able to convert the bootable ISO image to a bootable
+USB stick using a simple command line recipe, which I then can write
+to the most recently inserted USB stick:</p>
+
+<blockquote><pre>
+geteltorito -o usbstick.img lenovo-firmware.iso
+sudo dd bs=10M if=usbstick.img of=$(ls -tr /dev/sd?|tail -1)
+</pre></blockquote>
+
+<p>This USB stick booted the firmware upgrader just fine, and in a few
+minutes my machine had the latest and greatest BIOS firmware in place.</p>
