Many latop brands like Dell or Asus provide firmware files that you can put on a USB key and flash from an update application located in the BIOS menu itself. Different machines, different firmware updates How is that possible? Let me introduce you to an interesting new feature of the UEFI specification. It doesn’t even need the creation of a bootable USB key: everything is done from the existing Linux installation. Since I wiped Windows off my machine a long time ago, I was wondering if there was an alternative (and secure) way to flash firmware updates on it.Īnd it turns out there is! After months of investigation, I found an elegant and stable update procedure which doesn’t require Windows at all. System firmware updates are important, especially to mitigate newly found vulnerabilities like Meltdown and Spectre. It’s comparable to the Dell XPS 13 and runs beautifully under Linux, but one detail has always been bugging me: Lenovo only provides BIOS updates for its Ideapad laptops in the form of Windows 10 executable files. I’m the happy owner of a Lenovo Ideapad laptop (model 710S-13IKB).
