Warning: Removed fan-in from always-disabled I/O buffer

Hello Forum! This is my first post/question... I built a 16 bit register that connects to a tristate bus, but when I try and write to the register I can't. I get a quartus (compiler?) warning ...

I have not checked whether this will solve the problem you described, but remove dataBus from the process sensitivity list. That list should have just the clock and the asynchronous inputs (asynchronous reset in this case). See the documentation referenced at http://www.alteraforum.com/forum/showthread.php?p=3369#post3369 for coding guidelines.
