你可能想从头开始看linux。

Linux From Scratch (LFS)是一个项目 这为您提供了一步一步的步骤 说明如何建立自己的 自定义Linux系统，完全从 源代码。

你可能还想看看SharpOS，这是一个用c#编写的操作系统。

可以研究的一个相当简单的OS是µC/OS。这本书有一张印有出处的软盘。

当我开始开发基本操作系统时，我需要一个基本的指南，就像基本操作系统的踏脚石一样。这让我没有失去理智。

如果你想从无到有(纯汇编代码)

在简要概述了为X86平台编写操作系统所涉及的内容之后，还有很多链接。

看起来最有希望的链接(www.nondot.org/sabre/os/articles)已经不再可用，所以你需要通过Archive.org版本来阅读它。

在一天结束时，引导加载程序获取内核的机器代码，将其放入内存中，然后跳转到它。你可以把任何你想要的机器代码放在内核中，但是大多数C程序都需要一个操作系统，所以你需要告诉编译器它不会有所有这些，或者引导加载程序必须创建一些。

然后，内核完成所有繁重的工作，我怀疑它就是您想要的示例内核。但是，从拥有一个说“Hello world”的内核到拥有一个加载命令解释器、提供磁盘服务以及加载和管理程序的内核，还有很长的路要走。

You might want to consider subscribing to ACM to get access to their older literature - there are lots of articles in the late 80's and early 90's in early computing magazines about how to create alternative OSs. There are likely books that are out of print from this era as well. You might be able to get the same information for free by looking up the indexes of those magazines (which are available on that site - click "index" near the magazine name) and then asking around for people with a copy.

Lastly, I know that usenet is dead (for so sayeth the prophets of internet doom) but you'll find that many of the craggy old experts from that era still live there. You should search google groups (they have dejanews's old repository) and I expect you'll find many people asking the same questions a decade or 1.5 ago that you're asking now. You may even run across Linus Torvalds' many queries for help as he was developing linux originally. If searches don't bring anything up, ask in the appropriate newsgroup (probably starts with comp.arch, but search for ones with OS in the name).

对程序员来说是个有趣的问题。要构建像Windows或Mac这样的操作系统需要很长很长时间，但如果你想构建一个简单的操作系统，你可以尽最大努力

You need to focus on Assembly Language,C and C++. You should be expert in these languages. First read a good book on how OS works[Google it], then read all the info from Wiki OS Search in youtube "How to create your own OS in Assembly Language" watch the video, Eg. Video Download Linux OS source code and compile it yourself and try to modify the code yourself Now you are an experienced OS editor now download Minix and QNX and start developing with them and get their docs from here Minix Doc and QNX Doc

现在你已经获得了创建操作系统的硕士学位(不是完全的，只是再多一点)，现在把这些知识传播给你的朋友，并在他们的帮助下尝试创建一个像Mac、Linux或Windows一样强大的操作系统
