XtremeOS - An 8086 compatible OS written in pure X86 asm

Post by Prostyle44 »

Xtreme operating system is an ultra small and fast operating system written in pure x86 Assembly language. It`s main goal is to provide an advanced User interface for old 8086 Processors. The main goals which xtremeos has accomplished are.
1) Provide a fast and small operating systems.
2) Provides an advanced user interface
3) Can work on all X86 processors.
4) Requires only 64KB of RAM.
5) Works on a 320 x 200 256 color VGA screen.

This OS is not fully complete. Once it is fully completed I will post a link.

So, your target is user interface? It's a bit different area than the OS development.

Why is VGA the minimum required? My 8086 laptop is only compatible with CGA and the Olivetti M24.

embryo: No, my target is not only user interface. the target of this project is to provide an operating system with an more advanced and a more user-friendly operating system for the 8086 platform than any other operating system. I will also concentrate on the other parts of the operating system.

Octocontrabass: VGA is not the minimum requirement. I`m planning to add CGA and EGA support too. And after I`ve finished the operating system can you please test it.

I guess what embryo means by saying that your goal is to 'provide a UI' shouldn't be the first goal. The UI part of the system is usually implemented after a stable base has been designed and developed. After all why would there exist a UI? Too provide the user a way to access devices, files, programs etc.? Those need to be implemented first. I'm not going to interfere with your roadmap. You're free to implement and focus on what you want.

Once I get the laptop fixed, yes. (It needs some new capacitors, and I don't have the tools or skills to replace them.)

But of course! How else am I going to test the "your computer is not a 386 or newer" code? :lol:

Why not just use emulators that would emulate those systems. (Bochs?) Or are you just making sure it runs on real system.

Plus, where did you get those? Don't think you can easily find em in computer shops...or can you?
CookieOS. Want a cookie? Its only black and white for now though, probably as bad as my baking skills.

User friendliness can be elaborated a lot using graphics editor and simple program with drawing and animation capabilities. But (as already mentioned above) what is the world that you see so friendly? First of all there should be the world to display and play with. Usually this world called OS. And on top of the world we can draw our skins or screens or 3D animations or whatever we like.

Emulators are useful, but they usually don't cover the weird hardware (and BIOS) quirks that show up every now and then. Besides, running on real hardware is more fun!
hometue wrote:Plus, where did you get those? Don't think you can easily find em in computer shops...or can you?
Most have been given to me by friends or family, but a few came from secondhand stores. I wouldn't bother with computer shops; they only sell things that work! :lol:

Is the second screenshot real, or is it a goal or something? I ask because it's vastly different from the other one, and not something which I would expect to see in 64 K of RAM. If so it looks pretty good; if not then I'll just stick to DOS (at least DOS puts the current working directory on the command line LOL).
When you start writing an OS you do the minimum possible to get the x86 processor in a usable state, then you try to get as far away from it as possible.

The second screenshot is real and working. I have added an image of it running on qemu. I could achieve it under 64 KB because the background image type is PCX and is pcx images are easy to display. And the icons are created by my VGA API.

Haha, but XtremeOS currently does not have directory support. I will add it in the next version.

So your OS supports both CLI and GUI mode in under 64K?

sorry for my delay

Kind of, as the cli is an external program and the gui loads and executes the CLI program.

New features for XtremeOS are:-

1) Stepper motor control

2) Dial-up modem terminal

3) Basic Dos compatibility

4) Radio transmitter circuit support ( AM only )

5) Arduino Access

more to come...

Anyone who wants to join this project PM me.

This OS is going off-topic. It was supposed to be a small OS for old PCs - why are we suddenly doing Arduinos and Stepper Motors? As far as I'm concerned those only add to the memory consumption.

Also, I'm waiting for a download link so I can try it out.
