Here are the steps I used to upgrade the BIOS of my Lenovo Thinkpad X1 Carbon Gen 2.
You have to download the bootable ISO file from Lenovo support site, convert it and copy it to a usb flash drive.

You will need a USB key you can erase.

First Get the bootable ISO file from Lenovo support website. To get your product number:

sudo dmidecode -t system | grep Product

To check your BIOS version: sudo dmidecode -t bios

Get the geteltorito program from your packages or download it:

cd /tmp/
wget http://userpages.uni-koblenz.de/~krienke/ftp/noarch/geteltorito/geteltorito
chmod +x geteltorito

Extract the img from the ISO:

./geteltorito -o bios.img gruj09us.iso

Copy the img to the USB key (make sure sdb is you USB key!!):

sudo fdisk -l /dev/sdb #at least check that device size is right
sudo dd if=bios.img of=/dev/sdb

That’s it. Boot on USB stick and follow the instructions to update your BIOS.

Generate persistent udev net rules

Under Arch Linux, your network cards are sometimes named differently between two reboot. Configuring your network connection is hard if you don’t know if you card will be called eth0 or eth1.

A file /etc/udev/rules.d/75-persistent-net-generator.rules.optional can be used to tell udev to generate persistent network rules.

It’s very simple:

mv /etc/udev/rules.d/75-persistent-net-generator.rules.optional /etc/udev/rules.d/75-persistent-net-generator.rules

Reboot your system. A /etc/udev/rules.d/70-persistent-net.rules file has been generated. Now you can disable the generator:

mv /etc/udev/rules.d/75-persistent-net-generator.rules /etc/udev/rules.d/75-persistent-net-generator.rules.optional
