bios setup

We have over 20+ Dell Precision M6400 laptops pre installed with Red Hat Enterprise Linux version 5.x. I was asked to disable Wi-Fi on all laptops as it poses a serious security risk to our sensitive (classified) systems and networks. How do I disable wireless networking (802.11) under Linux?
