Abstract
Provided are techniques for status information saving among multiple computers. In one embodiment, a selected computer is operated using a plurality of input/output devices over switched input/output signal paths passing through a KVM (keyboard video mouse) switch positioned between the selected computer and the plurality of input/output devices. Status data is carried over signal paths passing through the KVM switch wherein the status data represents status information for a plurality of computers connected to the KVM switch. The status data passing through the KVM switch is stored in a memory coupled to the KVM switch. Other embodiments are described and claimed. Other embodiments are contemplated, depending upon the particular application.
