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.

Updating BIOS via Linux ? (self.linux)

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.

My favorite way to update BIOS is with an SPI flasher and flashrom.

Vendor lock-in miscreants like Acer get wrecked. Try and stop me.

Thanks for the suggestion.

I presume from your tone that it is safe to do. Because, I don't wanna brick my UEFI.

I have saved bricked systems with this flashing tool. Just backup whatever is already on the BIOS chip with

flashrom --programmer model_name -r /path/to/backup.bin

before proceeding, so that it can be copied back over if anything goes wrong.

Thank you. This is so cool.
