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.

    do you have a specific need to actually upgrade your bios at all?

    No, I’m just curious.

    1. Enter your Serial Number or select your model from the list.

    Those suckers don’t even have a page for my model. ( Acer One 14 Z2-493 )

    1. Double-click the file application file that was extracted to begin the install.

    Also, this works only on Windows right? Because they only provide .exe

      Correct - but the next thing I was going to suggest, you can extract the EXE i believe, if you peruse the archwiki link.

      It might be an exe you could run in FreeDOS, or you could extract the actual firmware file and install with another tool

        Yes, that’s possible.

        But, I am scared about screwing uy BIOS.

          That is always a risk when updating a bios!

          Depending on the motherboard (I think its more on desktop mobos) you get two bios chips, one used to recover from a bad flash of the other

          edit it could also be the case there hasn’t been a bios update released

              You might as well try. Had a similar issue with Samsung SSD, where they only had support for windows with a .exe, but which created a small Linux system that was installed in the UEFI boot position. So I searched for the Linux executable in the middle of all that mess and executed it directly. Problem solved.
