I have a X230 with QubesOS 4.0, which I would like to upgrade to 4.1
Prior to do that, I have to upgrade its firmware to 1.4 to be able to use the integrated ethernet.
My X230 firmware has the version 1.1
My question is: is it safe to upgrade it directly to version 1.4, or should I proceed step by step and upgrade it first to 1.2, then 1.3 and finally 1.4 ?
Thanks in advance !
