I am running Linux Mint on a Lenovo C530. I would like to upgrade its bios but Lenovo's official bios upgrade doesn't support Linux. The reason I want to upgrade the bios is to get the latest Intel microcode patches for security reasons. Do I need to actually update the bios for that or can I install them in a different way? If so, what would be the advantage of upgrading the bios?
Your computer may be supported by fwupd. Try this:
sudo fwupdmgr get-devices
If your UEFI is detected, use this command to update it:
sudo fwupdmgr update
