How to update Lenovo B590 Bios on DOS?



How can I update BIOS on DOS?

I read this post:


and this:


I found how to create bootable usb on Linux for FreeDos. But I can't add any file to that usb without clear instruction. I think I was able to add bios file for a few times via Debian instructions here: But DOS says something like this "the exe file can be run under Win32"


Debian, Ubuntu and Linuxmint give hardware errors on boot.

I think if I update BIOS it should be solved.


Current BIOS: H9ET69WW (1.06 ) Release Date: 11/15/2012

Latest BIOS I want to install: H9ET92WW


My second question is that if I update BIOS, should I also update UEFI? If yes, how can I do it? Because Linux or 64 bit Linux uses UEFI only.


To Lenovo staff: I particularly bought Lenovo laptop as I heard Lenovo is one of the few brands that can run Linux. But Lenovo doesn't provide BIOS update for Linux. There is only microcode for Linux and it's not sufficient to call Lenovo as a Linux friendly laptop brand.


I appreaciate your answers.
