Abstract: The time required to boot a computer is reduced by reducing or eliminating the need to discover many or all devices within the computer and the machine topology. Access panels are monitored so that it is detected when they are opened. For the access panels that have not been opened, it is assumed that the system configuration, topology, devices, etc. have not changed since the last boot process and there is no need to spend time discovering these devices and machine topology. Stored, instead of discovered, configuration information is then used to configure these devices. This reduces the time required to boot since discovery of devices is not performed. A service processor or other logic may be used to detect which access panels are opened. Also, only those elements of the configuration that may be affected by the particular access panels that were opened need to be re-discovered.

Abstract: A circuit breaker system designed for three-phase, four-wire, delta-connected electric panelboards or loadcenters allows users to derive 120 volts from vacant full size higher voltage leg bus spaces. Two independently operating circuit breakers arranged side by side, in a "side-car" configuration, allows both breakers to electrically connect with a 120 volt bus while positioning one breaker in a vacant full size high leg bus space. The use of an electrically conductive bridge running between the breakers allows the second breaker to be positioned in a vacant high leg pole or full size space while receiving 120 volts from the first breaker. The result provides the user with a breaker in a full size vacant high leg space that can be used to power 120 volt to neutral circuits. This system is capable of providing additional 120 volt circuits in a cost-effective manner without violating the National Electric Code.
