From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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.

I had an Acer laptop once. I had Ubuntu on it. I had problems with random crashing after a few minutes, I ran memtest, it took a few hours for a full test and came back with a whole slew of faults. I sent it to Acer under warranty and they told me that Linux was the problem and I should leave windows on it.

I called the "technical" support regarding this issue. And they said they'll only support Windows.

Making your entire hardware reliant on particular proprietary software like Windows is just stupid.

Never buying Acer again.

At this point, I don't even know which vendor to buy, when everybody is shit.

Tuxedo, Framework, Slimbook, System76, Starlabs are Linux-first vendors with an excellent track record.

All the security updates are in the microcode loaded by the bootloader even before the kernel is loaded, so unless there's some new feature, bugfix, or hardware support you specifically know you need it's not important to update your BIOS anyway. Which is good, because as far as I can tell you're just screwed by a bad hardware vendor.

not important to update your BIOS

Not actually gonna update BIOS. but just curious.

bad hardware vendor.

Which accurately translates to Acer.

Sorry, but in your case the only way is to install Windows. Make a dual boot.

Thank you.

I think it's stupid to provide something hardware related like BIOS exclusively through a particular proprietary software like Windows.

There is no universal solution to this. Some vendors support fwupd (LVFS) on some hardware (Dell, Lenovo), some allow to update via a file on a USB stick (Asus).

Unless it is a system from Linux first company (Tuxedo, StarLabs, System76, Slimbook) expect to manually check what the specific model you are looking at supports.

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

Also, I don't think fwupd has firmware for this particular laptop. ( Acer One 14 Z2-493 )

That's the thing - there is no option to update BIOS on Linux then.

You must install Windows or maybe use one of those unofficial Windows Live USB images.

Depends on the exact model. The usual way on Linux is via fwupdmgr.

Try it out. I was often pleasantly surprised by the things provided by fwupd.

Is there an option to save the new bios update file to a USB stick, then enter bios and trigger an update manually that fetches the file from said USB stick?

I've done it this way with an Asrock motherboard for desktop running Bazzite.

I feel your pain. I've searched a bit online and found several different methods (not for Acer though) that all go way over my head. I just leave the BIOS to deprecate on its own by now.

As someone who's built his own PCs for years, I've never really bothered with a BIOS update.

Then again, one of the main reasons to update BIOS is to gain support for new CPUs, but I've been using Intel which switches to a new socket or chipset every other generation anyway. I've almost always had to buy a new motherboard alongside a new CPU.

I don't have reason to update BIOS either. But just in case.
