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.

    Most BIOS updates come with a firmware file and a .exe to flash it

    Sadly in my case, iy doesn’t.

    how do you know they exist?

    Sorry, I wrongly remembered. It’s my other laptop which has a new bios update.

      I think they’re saying the Windows update file will contain the firmware binary.

      You can find Windows update files here: https://www.catalog.update.microsoft.com/Search.aspx?q=Acer

      But you’ll probably have to check each update and see if the “Supported Hardware IDs” match some sort of UUID in dmidecode. I’m not sure if those are supposed to match though.

      Then there are some generic firmware update tools for Linux that might work, or might brick your laptop.
