Writting an os

I would like to write an OS and i have some questions
(i would like to write it in java but i know this is not possible).
if anyone could answer these question i would be grateful
1. what programing languages would i have to learn notating what i said above.
2. is there any tutorials/sites i can use for help.
just so you know i also posted this topic an hour ago at http://forums.devx.com/editpost.php?do=editpost&p=463518

Why not try smaller projects first? I think you're biting off more than you can chew. It's certainly more than I can chew, that's for sure. But I suppose there are a number of simple operating systems out there that you could study and get ideas from.

And actually, when I Googled the subject, there where some very interesting ideas that maybe you should look at:

C++ and assembler and you must be a blackbelt expert in both ... also you should have an expert knowledge of the system architecture you're dealing with

You can write OSes in java - here's one, but as 'lint said, you're going to need all sorts of low level knowledge. For what it's worth, most OSes at the moment are written in C/C variants (Windows, BSD, OSX, Linux).

I recommend you start with a small "toy" OS - there are plenty out, and have a good hack at it. You might also want to lurk on the linux kernel mailing list.

Oh - and this is a good resource.

That's kind of what I was grasping at, but the names of the well known ones where not poping into my mind...

GeekOS is an example of a "toy" OS that you may want to look at

Proxy for simon, please! Bloody love spreading requirement.

This is actually quite an interesting project. I may have a gander at it later on when I'm not as busy.

I do knoow java quiet well whatdo you mean by first project?

Well... What I meant was that if I where to try to build an OS, my head would explode. Bang, nothing left.
