title: Drawing pixels in C: OSdev
body: <p>I’m totally beginner in osdeving. for now i’ve just implemented keyboard and vga screen following the osdevwiki. Now i’d like to draw proper pixel like this</p>
  
  <pre><code>void drawPixel(int x, int y, int rgb)
  </code></pre>
  
  <p>in freestanding C language.
  now, in vga mode the address for printing text and colors is 0xB8000. To paint pixels in the screen how can i do? i don’t have any clue.</p>
