Picture of Create your own operating system!

Nearly every true computer geek has, at some point, wanted to write an operating system. However, writing a custom kernel and other bits takes years of study, experience and patience. If you intend to keep your sanity, then the best course of action is to use someone else's code.

Cosmos*, or C# open source managed operating system, is a pre-made kernel that provides you with "OS legos" that allow you to quickly and easily create your own operating system.

You will need:

@ Microsoft Visual C# 2008.

@ A knowledge of the C# programming language (don't worry if you don't have this, it's a pretty easy language).

@ The Cosmos user kit (milestone 4).

Step 1: Getting the software

Picture of Getting the software
Let's do a run down of the necessary software mentioned earlier.

Microsoft Visual C# can be downloaded free if you get the express edition. You can download it at http://www.microsoft.com/express/downloads/ You can also download the entire Visual Studio including visual basic and visual c++ as an ISO image (these can be tricky, see below for details on reading ISO images). Even on a blazing fast computer, downloading visual studio will take two hours at most, though.

WARNING: make sure that you get the 2008 edition and not 2010. This may seem backwards, but the Cosmos user kit has yet to support 2010.

The cosmos user kit is the platform that we will write our OS in. It's an all-in-one micro-kernel operating system that is written in 100% C#. You can download it at http://cosmos.codeplex.com/releases/view/35194



A note about ISO images:

If you opted to download the entire visual studio, then you're going to need to read the ISO image file. An ISO image is a map of a virtual DVD, using the same encoding as any other disk. You have two option: Use a program like nero or roxio to burn the image to a CD-ROM then insert that disk into your computer and download it (The latest Windows XP comes with Roxio, and Windows 7 comes with Nero pre-installed. Other than that, you will almost certainly find something on your computer that will burn a CD. Explore a bit), or you can use Daemon tools lite edition to read the file directly.


Daemon tools lite is free and can be found at http://www.daemon-tools.cc/eng/downloads

A: After downloading it, running the setup program, and re-booting, fire up Daemon tools and click Add File (the picture of the CD with a plus sign).

B: Find the image, and open it.

C: Now, select the file and click Mount. A popup (see pic')  will show you some options, click "run setup.hta". This will install Visual Studio. Alternatively, you can find setup.hta in the virtual drive that was created, located in My Computer under Devices with removable storage.

Yes I love the ideas put forward by you guys all. In fact I will be amazed if you are all able to built an OS with those feature mentioned above. But that is easy said than done. Making an OS require a lot of experience in OS internals and not just being able to do programming. Programming is one thing and making an OS is another thing all together. If you want to make an OS, I will advice you start learning about hardware (deep understanding), OS internals (behavior, requirements, tools needed) - the software part. You will also have to learn deep about the libraries used in making the programming language you want to use and its runtime since you will implement them again in your OS.

I also have ideas about making an OS with feature I have also taught of, using the "D programming language". But I know I will have to do a lot of research before I start to even plan.

Anyway, you can contact me and we will talk more about OS development. I love great ideas but the requirement is commitment.

Is it easier to Develop an OS from UNIX

Nice tutorial, could you make one that uses VB.NET instead of VC#.NET?

Alrighty, so I am trying to use Visual C# 2010 Express with the newest version of Cosmos. So it works, but when I build it, I get an error. And that's with the default code! I did add refrences to Cosmos.Hardware and all that and it still doesn't work! The error is about Cosmos.Hardware.Hardware... cant find it? Do you know of any way to fix this? If I use MS4 is 2008 Express, it works like a charm. But I want to use the newest version! Any ideas? Also, thanks for a great tutorial! It helped a lot! :)

Hi everybody, I have plan to make an operating system with newest technology:

Artificial intelligence: Devices using this OS can communicate with other devices and people like people communicate together.

Very Easy: Anyone can use it, from very young to very old with simpliest command.

Run on any device: Robot, smart armor, watch, mobile, compute, ring, home,...

And Cloud, IoT, AR,...

AI is core! And we'll make new programming language for this OS.

Some new hardware will coming with this OS too.

Contact me at: ozonspacing0602@gmail.com if you interested.

I need somebody known: Assembly, graphics, security, AI, hardware.

Hey; is anyone interested in designing a NEW operating system? (yes, of course) I plan for it to be a simple beginner's project, requiring minimal involvement (not complex). I need a few helping hands. I happen to know C 98, C++11 (working on 2014) and am learning NASM assembler. I need someone who knows Assembler and Linux systems, in general. If you can help (and are interested), please contact me:

I'm already working on an operating system. It's called Fallen OS, and if you want to help, I'm looking for someone who knows assembly. Contact me at Klyk.exe@gmail.com. It's Gaming based, and uses a GNOME interface.

Hi,

I'm Joe, I am a 13 year old programmer with medium visual basic knowledge.

I can make programs like advanced web browsers, database tools, system information and tweaking utilities. etc. Have had about 7 years computer technic experience and about 2 years programming experience. (Self taught.)

Contact me if you please,

Joe Channing

Hi I'm Aaron. I have no computer programming knowledge but I have some really great ideas for UI design, but the problem is that I have no way to display them or ever have them come to fruition without someone with extensive programming knowledge. Thanks!

Hi! I have a bit of skill on Visual Basic Programming, i can make medium difficulty Windows Applications, not a big fan of Visual Studio Online.

In a scale if 1 to 10, 1 being a dude who just made a .bat app, 10 being the best programmer at Microsoft, i think i'm a 5, 6. I'm learning C# at the moment!
