Let's begin with a simplest boot sector. You'll see how easy it is to get started!

Here we go:

• Install nasm the assembly compiler and bochs the emulator

• Clone me (we're in GitHub, aren't we):

  $ git clone https://github.com/yyu/osfs01.git
  

• Run your smallest "OS" right now:

  $ cd osfs01
  $ make
  

  Guess what? It's running!

  

  The screen is a little messy but you can see the red "Hello, OS world!", which means our boot sector works!
