<h3>Main Flow</h3>

The kernel is composed of 6 modules: video, strings, sound, maths, ports and main.
<br /><br />
The main function invokes to following tasks:
<br /><br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
-initialize the video mode 640x480x16<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
-draw the rotatable logo<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
-draw the no rotatable logo<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
-print the screen messages<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
-read the password<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
-if the password is correct, then fill the screen with "babel"<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
-else restart the pc<br />&nbsp;<br />
Because we do not have threads to synchronize the rotation of the squares we need to do a pseudo synchronization.<br />
