+/* The keyboard driver works with a device called PS/2: to talk with this

+ * data is made with "commands", each command is one byte and the keyboard's 
+ * controller can send two type of response:
+ * ACK(Acknowledge): to acknowledge the previous command
+ * Resend: to resend the previous command due to an error.
+ * We have also to wait between the command, the data and the response of

+ * This device should not exists anymore in any modern computer
