Can anyone point me to a good resource on updating the BIOS/firmware under Linux?.

I know absolutely nothing about it, and it looks like the user has to manually do it. And the obvious question: How do Windows users do it? When they are even less knowledgeable than me (generally speaking).

Newer laptops supported by fwupd (fwupd.org) are more straightforward on linux. For the older ones, you take their windows bios image, and use Geteltorito (https://wiki.archlinux.org/index.php/Flashing_BIOS_from_Linu...). Windows users open an exe file.

There was some unofficial tool to flash firmware on Linux. When I took my Carbon to IT, they just booted Windows off of an external SSD disk.

Also, LVFS: https://fwupd.org/lvfs/component/1023/all <- to me, personally, this didn't work. I suspect it had to do with UEFI mode.

`man fwupdmgr` I ran the few commands in the link [1] and it worked just fine, lots of beeping scared my coworkers tho.

Just don't forget to change the Power setting in your BIOS to Linux, as mentioned in the link as well.

There are links in the article showing how to update the BIOS from Linux. It involves downloading the firmware (a couple of megabytes in a .cab file) and flashing that onto a USB stick from which you can boot.

Windows users do it differently. The carbon has an auto-update service installed which will offer to update the BIOS when it finds a new version available.

Usually you put the firmware file inside the UEFI partition and then update from the bios. It's very simple.

I got a BIOS update through Windows update once. Didn't have to do anything except deal with a random restart.
