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 +download +from Lenovo 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.
+ +The geteltorito program in +the genisoimage binary +package 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:
+ ++ ++geteltorito -o usbstick.img lenovo-firmware.iso +sudo dd bs=10M if=usbstick.img of=$(ls -tr /dev/sd?|tail -1) +
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.
