Hi everyone, I have just recently found out there is a thing like coreboot/libreboot, and I like the concept of it: fast(er), secure, open source, easy to flash and non-brickable process.

I’ve been trying to understand the basics behind it and it’s too difficult for me. I have some basic understanding of what BIOS / EFI is. And as I understand it, the core/libreboot is an open-source replacement for it. Great!

But what I’m interested in is understanding, how it manages to be better than the OEM’s BIOS? I understand that the nature of open-source is better than closed source software, but what I don’t understand is how this project manages to be better for end-user?

As I get it, it’s similar to Custom ROMs on Android. There is an OEM’s rom — say, Samsung — it makes its version of Android, and it’s good (in terms of how it works with the hardware), but usually with tons of bloatware and OEM never updates the phone after a customer bought it. Here we have Custom ROMs, like CyanogenMod / Lineage OS / Pixel Experience / etc. etc. Those ROMs somehow manage to keep the software updated for much longer time-frame, having extra functionality and even working faster. (Frankly, I don’t understand how do they manage to do that as well, and why it’s so difficult for OEMs.)

Is this something similar? I can understand the (ineffective) processes of big corporations, but I cannot understand how the developers manage to keep those things better, lighter, etc. Say, whether the OEM’s firmwares somehow bloated? Why is so then? Why won’t a big company like Gigabyte, Asus, Acer, etc. also use this product, why do they write so-closed-source BIOSes and EFIs then, if they can use something lighter and faster, and in so many ways better? As it’s advertised on the website of coreboot.

I’m not sure I keep the question simple, for others to understand, but if talking about the real hardware. Say, I have Asus MAXIMUS IV GENE-Z motherboard. Can I install coreboot on it (seems like yes, according to the website https://coreboot.org/status/board-status.html#asus/maximus_iv_gene-z), and if I can, will it miss some functionality comparing to its original EFI? I mean not that I need it, but I’m interested whether there’s something special in original firmware or not. There are many things on the website, at ‘ROG Exclusive Features’ and ‘Special Features’ sections, but I’m not aware if it’s something special or it’s just some marketing bullshit, is it located in the firmware, or it’s something entirely different they speak of in that section?

Please pardon me if the question is too newbish and was answered somewhere. I’ve tried to do my search and found no information on my question. I would appreciate any comment on this topic. Thanks!

edit: Found Why use coreboot? (reddit post) And it’s an interesting read itself, but it’s not the question I’m trying to find answer to.
