Two techniques are described whereby personal computer systems, such as the IBM PS/2, can be enabled and disabled without a keyboard attached. The concept is particularly useful for systems in remote installations, or for security reasons when the keyboard should not be installed. One technique uses software only to enable the system to operate without a keyboard. The other technique is a hardware implementation to provide the proper signals to take the place of the keyboard, through the use of an intelligent terminator. Personal systems are designed to test many function through power on self test (POST) operation. One of the functions is the detection when a keyboard is not attached. However, there may be occasions which require operation without a keyboard.
