Creating an Operating System compatible to any systems

Creating an operating system even it is possible is such a big task, if you need to be able to use hardware, give an apropiate user interface, manage to make it fast and moreover making it compatible with all the other existing ones out there and a long etc...

If you want to do that you should start looking at some open source small linux distros that would give you an idea on the amount of job you will have to do.

Good luck and of course if you have further and more specific questions than that, come back and we will try to help.

Yes it is quite possible - but it does require some effort.
You can get some samples / tutorials on how to get started etc if you do a search on the internet.

What you're really asking us to do is to comment on YOUR ability to write an operating system. If you're here asking that question, I'd have to say that no, it's not possible for YOU to write an operating system at your current apparent skill level. maybe at some later date, but I have a feeling your interest will lie elsewhere by the time you have the programming chops necessary to write an operating system.

Just sayin'...

Consider that a large team of people, each one of which is far too experienced to ask this sort of question in a public forum, have worked together to create the OS you use today. Then ask yourself, if you wrote an OS, who apart from you would use it, and why ? Learn basic stuff first, write an OS when you retire.

Yes indeed, both Bill and Linus developed OSs when they were younger.

One thing that strikes me immediately, that no-one else has mentioned is the difference in your approaches, with the obvious exception of John Simmons.

Bill & Linus differed in so far as they were each convinced that they could make an os... Heck, Bill sold his OS before he even had it finished..

I too suspect that the question reminds me of the old addage: "If you have to ask how much, you cant afford it"


But.... That said - why don't you break out an assembler and start writing some code to put into the boot-sector of a floppy-disk (or presumable if you've moved with the times, a usb drive).
This is reasonably trivial. Try loading a boot-loader then copying that to the boot sector. Once you receive output from this code, try loading a file that is either (a) given a specific name or (b) placed in a specific sector of the disk.

I mention (b), because dont forget - you only have 512 bytes for this boot-loader.
I made a program that showed a 3d rotozoomer back in the day, though was never successfull in the next step - actually loading something other than the boot setctor, which was obviously loaded for me by the bios before having control passed to it.
