I only wish I had found it previously!&lt;p&gt;OS dev can be great fun and gives you a level of understanding about how computers actually work that is hard to gain from other sources. I have frequently found myself using the knowledge I gained from building the OS when working on other projects. It has been particularly useful when it comes to understanding performance issues. I would highly recommend it to anyone that is even remotely interested.&lt;p&gt;Other superb resources to help you get started include the OSdev wiki[1], along with this document[2] from the University of Birmingham, UK.&lt;p&gt;[0] &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;www.hydros-project.org&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.hydros-project.org&lt;/a&gt;&lt;p&gt;[1] &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;wiki.osdev.org&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;wiki.osdev.org&amp;#x2F;&lt;/a&gt;&lt;p&gt;[2] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.cs.bham.ac.uk&amp;#x2F;~exr&amp;#x2F;lectures&amp;#x2F;opsys&amp;#x2F;10_11&amp;#x2F;lectures&amp;#x2F;os-dev.pdf&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.cs.bham.ac.uk&amp;#x2F;~exr&amp;#x2F;lectures&amp;#x2F;opsys&amp;#x2F;10_11&amp;#x2F;lectures...&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>The little book about OS development</title><url>http://littleosbook.github.io</url></story>
