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.

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.

[–] [email protected] 9 points 3 months ago

unofficial Windows Live USB images.

I just came to know about this

[–] [email protected] 7 points 3 months ago (2 children)

system from Linux first company (Tuxedo, StarLabs, System76, Slimbook)

Indeed that's IMHO the solution, namely prioritizing ecosystem that genuinely see Linux as something valuable, with an addressable market, rather than a cost linked to annoying users.

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.

[–] [email protected] 34 points 3 months ago* (last edited 3 months ago) (2 children)

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.

[–] [email protected] 49 points 3 months ago (5 children)

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

[–] [email protected] 9 points 3 months ago

3mdeb, Novacustom, Pine64

Minisforum is also said to work well.

[–] [email protected] 8 points 3 months ago (1 children)

I know and Framework is just mouth watering. And Chad76 created their own distro and DE.

it's just sad that they are not selling on my country.

[–] [email protected] 6 points 3 months ago

Framework uses proprietary BIOS. They ditched coreboot, which is pretty bad.

Afaik they were also a lot behind on updates.

Have a look at Starlabs. You can choose coreboot

reminder to myself to remove the ssd next time i need warranty repair

[–] [email protected] 8 points 3 months ago

A 128 or 256 GB SSD or NVME drive costs £10 to £15 on eBay used. I would buy one and put Windows on it when sending back for warranty repair. OP should actually just do this for the BIOS update and then swap out the SSD back to the Linux one after.

[–] [email protected] 10 points 3 months ago

Had something similar with ASUS…never again

[–] [email protected] 19 points 3 months ago (1 children)

Install windows on a second/spare drive. Boot PC from this and run their tool.

I know you're trying to find a way around not using windows, but if the vendors only solution involves it, I wouldn't trust any hacky workarounds when it comes to bios updates.

And this is one more reason I will only buy a laptop from System76, Framework, or Tuxedo to run Linux.

All motherboard manufacturers irrespective of OEM should provider a firmware mode that can be boot to, allowing BIOS upgrades. But since they don’t seem to, especially with laptops, seems best to stick with known vendors whose primary OS they support is Linux.

Good luck, OP. Hope the live Windows USB thing works. Just be careful to not get infected with Recall or any other Microsoft nonsense :)

Razer was the worst. It had to be done thru a ‘legitimate’ copy of the latest full Microsoft Windows (no old Windows, Windows PE, FreeDOS, etc.) & the purpose was to give you a black+green GUI experience. After I emailed them about this several years ago when I had a Razer laptop, they put up a sign on the support page now saying installing Linux voids both you warranty & any support tickets.

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.

[–] [email protected] 5 points 3 months ago

They don't even provide BIOS file in the first place.

[–] [email protected] 8 points 3 months ago (1 children)

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.

[–] [email protected] 6 points 3 months ago

not important to update your BIOS

Not actually gonna update BIOS. but just curious.

bad hardware vendor.

Which accurately translates to Acer.

[–] [email protected] 7 points 3 months ago

if the provide and exe, You can always create a bootable usb stick of freedos or another dos tool. Copy the file onto the stick. boot to it and cd to where the file is and issue filename.exe

[–] [email protected] 7 points 3 months ago (1 children)

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

[–] [email protected] 2 points 3 months ago (1 children)

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 )

[–] [email protected] 8 points 3 months ago

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

[–] [email protected] 7 points 3 months ago (1 children)

Frankly in my opinion, bios should only be updatable from the bios itself. No matter which os we talk about, it can always get in the way.

[–] [email protected] 6 points 3 months ago

Thank you sane person.

[–] [email protected] 5 points 3 months ago* (last edited 3 months ago) (1 children)

Acer has had this policy for over 20 years. I bought a laptop long ago from a vendor that I had issues with and they refused to give me support because I was running Linux at the time. (I forget what distro. Probably either Mandrake or early Ubuntu.) That laptop went right back to the vendor.

Never bought anything from them since.

[–] [email protected] 2 points 3 months ago

What a joke they are.

[–] [email protected] 5 points 3 months ago (2 children)

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.

[–] Technus 11 points 3 months ago (1 children)

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.

[–] [email protected] 2 points 3 months ago (2 children)

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

Usually you can extract the windows updater exe and use the bios/bin/upd file via mainboard bios update mechanisms

[–] [email protected] 2 points 3 months ago

They don't even provide BIOS file in the first place. So no exe to extract.

[–] [email protected] 4 points 3 months ago* (last edited 3 months ago) (2 children)

I know for HP machines, the bios updater exe can be decompressed and you can just get the bios image and the signature file from that.

Idk what machine you have, but at least for an older aspire laptop my friend has, there is a bios download.

If you follow instructions to make bios recovery media, you can update your bios through that.

Edit: that Acer laptop you have doesn't even show up on Acer's support page. Supposedly it's sold as an Acer aspire a something or other. If you search based on your snid, you should be able to get to a downloads page.

Also clevo seems to make this laptop, according to the Acer India webpage I found for it

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

[–] [email protected] 6 points 3 months ago

Thank you.

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

[–] [email protected] 3 points 3 months ago (1 children)

I know some BIOS update that works with FreeDOS.

Just basically need to flash it into a USB drive and run the BIOS update .exe with it.

[–] [email protected] 3 points 3 months ago* (last edited 3 months ago) (1 children)

There's no exe. They don't even provide BIOS file in the first place.

[–] [email protected] 2 points 3 months ago (1 children)

What do they provide then?

Also, in Linux there's fwupd

[–] [email protected] 4 points 3 months ago (1 children)

Updates via Windows update

[–] [email protected] 2 points 3 months ago (3 children)

Nothing on their download page either?
