Making your own super simple OS??

[LiquidFox]

Hi, I am just curious that is there any guide or course that teaches you how to build my own Simple Operating System??

Before you guys say " GOOGLE IT, " I wanna say that i googled it and found nothing useful!

Yeah. You need strong programming knowledge, especially in C and assembly and good fundamentals of math, especially in alogrithms as perequistutes. OS is literally run by insane number of threads (thousands) so you got to have good knowledge of multithread programming. You will probably get half baked results full of bugs and a kernel that is barely functioning. However if you can archieve this, it is already a job well done.

learn C# or C++

 

i think visual studio 2016 would be your best bet

I don't think you even remotely understand how complex an operating system is.

Maybe start by learning how to program?

Do you have a reason in mind for why you want to do something like this? Or do you just think it would be cool to do? There are plenty of "simple" OS's out there you can download right now if that's all you're looking for.

That is why I mentioned "Super Simple" mate!

Learning C++, Python and C# is in my school syllabus, so I wanna do something cool with this knowledge so I started thinking can I make a SUPER SIMPLE OS??

Okay, that makes sense, but in my opinion I think there are other projects you could take on with C++, Python and C# that would help you learn them well. I know you want to make a "SUPER SIMPLE OS" but I think what everyone else is saying is that there is no such thing as a "SUPER SIMPLE OS". There are basic operating systems, but they are not simple to code and likely not a good way to start with learning modern programming languages

That's like asking how to build a super simple nuclear fusion reactor.

 

First learn programming, then get a university degree, then get a masters or Ph.D and you should be able to build a simple operating system.

We've all at one point searched it up, it's possible through the power of school.

Well I've heard good things about Linux From Scratch, but I've never done it.  I'm not sure if it's still up to date.  Anyone here ever tried going through it?

[SmokeyTheBlair]

Try a new approach.  Instant loading, hardcoded OS.  This existed for MS-DOS 3.x many years ago but Windows and other detailed GUI OS can't really load that way.

 

You could also aim for an improved file manager.  Windows 3.x had that kind of idea. It required MS DOS to launch it and didn't contain any of the driver or config setups we expect from an OS.

 

I'll keep watching for updates.  People told Bill Gates he wasn't going to be able to succeed as well.

Linux from scratch is an already functioning OS for you to tweak with. You won't probably need to do anything except working with the command lines. Coding your own is on an entire different league. There is a difference between creation and utilization my friend.

Download the source code for FreeDOS : https://sourceforge.net/p/freedos/svn/HEAD/tree/

 

It's about as basic as you can go, you see how it interacts with bios, how it implements accessing file systems (fat12, fat16,fat32), how to do command prompt etc..

 

Or you can check out ReactOS (and the source code is freely available), which aims to be make an operating system that's compatible with Windows (so you can run Windows apps within it without having to modify the apps in any way) : https://www.reactos.org/

 

There's also uclinux (linux for microcontrollers), a linux version for simple microcontrollers (so the source code should be smaller, but not necessarily easy to understand): http://www.uclinux.org/

 

A lot of routers, printers , various devices use embedded linux stuff like busybox (though it probably isn't a good starting point to learn stuff) : https://busybox.net/about.html

You could look at very old versions of linux and maybe learn something:

I'm going to be a harsh person here. Do you even know what the point of an operating system is? If you do not, then how can you expect to build one? First figure out what the whole point of an operating system is. Once you have that foundation, then you can start looking at ways to build one.
