Disabling A Keyboard
Keyboards are an essential peripheral for all computers, except servers. In many cases, network administrators would prefer to restrict direct access to the server, and prevent potential tampering. Traditional PCs did not allow you disable the keyboard, but newer systems do offer a CMOS setup entry that can enable or disable the keyboard. When the keyboard is disabled through CMOS, the PC will boot without suffering Keyboard not found errors. Before starting service on a server, it might be necessary to reattach and reenable the keyboard.
