How to update BIOS on a system that only use Linux as OS.

Asking this because some clowns at Acer decided that they will only provide BIOS updates through Windows Update.

Edit: I’m not talking about installing the BIOS file. They don’t even provide BIOS file in the first place.

    This is a large part of why I try to buy hardware with coreboot support. Your best option is probably to get a cheap 2nd drive and have a Win install on it. I’m pretty sure you can run win 10 off a USB, that would probably work, just make sure you change the drive boot order in the BIOS for the update.

    My favorite way to update BIOS is with an SPI flasher and flashrom.

    Vendor lock-in miscreants like Acer get wrecked. Try and stop me.

      Thanks for the suggestion.

      I presume from your tone that it is safe to do. Because, I don’t wanna brick my UEFI.

        I have saved bricked systems with this flashing tool. Just backup whatever is already on the BIOS chip with

        flashrom --programmer model_name -r /path/to/backup.bin

        before proceeding, so that it can be copied back over if anything goes wrong.
