Disclosed is a host adapter having automatic termination, and a method for implementing the automatic termination. The host adapter includes a first connector for connecting to at least one external peripheral device and a second connector for connecting to at least one internal peripheral device. The host adapter further includes a termination system circuit that is coupled between the first connector and the second connector. The termination system circuit is configured to produce bit data that is indicative of whether a peripheral device is coupled to one or both of the first connector and the second connector. Preferably, the termination system circuit communicates the bit data to a software termination engine upon boot-up to enable or disable a termination of the host adapter. Furthermore, the termination system circuit includes a termination control decoder and a tri-state buffer. The host adapter also includes a termination over-ride control that is configured to over-ride the automatic termination generated by the termination system circuit via a software control.
