Firmware informatoion from a noob

[Link93]

Hello,
I just want to start this thread off by making it totally clear that I have NO knowledge on the issue.

I am just wondering what "OS" the antminers are running. I understand that there is a linux distro delivered from Antminer. But there are customs out there, so others seem to be able to create their own.

What I am wondering is what is that "OS", and what would it take to learn some of it. Any recommandations are greatly appriciated!

Would be cool to be running my own firmware for my S9's. I am also fully aware that this might be hoping for way to much, and that I should lower my excpectations, but this got me interested so why not give it a try

Again, new here so please be nice xD

EDIT:
Would just like to appologise if I am asking in a stupid way, and also my hottible English. Second language.

Almost all firmare stock and custom are based on Cgminer, it is an open-source project under the protection of GPL (General Public License), it was meant to be open-source and people should work on improving it, but then companies like Bitmain decided they no longer want to publish the source code for their modifed version of Cgminer (BMminer).

What most custom firmware devs claim to be using is the BMminer with their own modifications.

The best two members who know all about the firmware "in no particular order" are taserz and thierry4wd, they both have their custom firmware and they would probably guide you on how to start.
