Updating BIOS via Linux ? (lemmy.today)

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.

OH I misunderstood.

What is the exact model of ~~laptop~~ Acer device?

edit

I know this is an absolutely cop out answer but, do you have a specific need to actually upgrade your bios at all?

From the linked page

Visit the Acer Drivers and Manuals page .
Enter your Serial Number or select your model from the list.
Select BIOS/Firmware and click the Download link for the BIOS you want to install.
Open the folder where the file downloaded to, then right-click on the file name and select Extract All.
Double-click the file application file that was extracted to begin the install.
Follow the instructions on the screen to install the BIOS. Make sure you have an AC adapter connected.

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

No, I'm just curious.

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 )

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

[–] breadsmasher@lemmy.world 4 points 3 months ago (1 children)

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

[–] gpstarman@lemmy.today 1 points 3 months ago (1 children)

you can extract the EXE i believe

Yes, that's possible.

But, I am scared about screwing uy BIOS.

[–] breadsmasher@lemmy.world 3 points 3 months ago* (last edited 3 months ago) (1 children)

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

[–] gpstarman@lemmy.today 3 points 3 months ago (1 children)

There is a new BIOS update. But I think I'm just gonna leave it at this point.

[–] TheFrogThatFlies@lemmy.world 2 points 3 months ago

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.
