This text will teach the basics of what is needed to create a basic operating system. Recommended for advanced users.Instructions





Things You'll Need:

• 
  A programming tool with compiler.
  
• 
  A spare computer to test your new operating system.
  

1. 
   Step 1
   
   
   First, you must develop your control programs. These are
   what control and maintain your computer. The program must be in the
   form of firmware (loaded into the ROM, so a user can't accidentally
   delete an important file.) This will generally be classified as an
   initial program loader. An example of how this should work (chain of
   events, not actual code): Turn Computer On >> Memory chips are
   automatically activated >> The Initial Program Loader should read a
   boot sector routine (located in primary memory).
   
2. 
   Step 2
   
   
   Congratulations, your OS will now read a few things. Can't
   have input, so let's fix that. You'll need some support control
   programs, such as a linkage editor, and a Input/Output Control System.
   
3. 
   Step 3
   
   
   Lastly, add the utility programs. These are programs like MS-DOS's FDisk, FORMAT, ATRRIB, FIND, etc...
   And you're done! It's not exceedingly difficult IF you know what you're coding.
   

jQuery('.article ol .image').each(function(i,e){
var $this = jQuery(this);

$this.find('img').error(function(){
jQuery(this).remove();
$this.remove();
});
});

Tips & Warnings

• If
  you get lost, I'd suggest looking at some example/open source code. A
  decent Windowsesque one I found is here:

• Keep your code organized.
  
• If
  you're going to use it, and take it for a drive over the net, be
  careful. Running an OS that's very similar to current major OS will
  often lead to poor security, letting even mere script-kiddies gobble up
  sensitive information.
