Abstract: A computer system comprises a system trust module for taking measurements for platform specific firmware during a system boot and a trust subsystem comprising a subsystem trust module for taking measurements for software provisioned on the computer system. The subsystem trust module is in communication with the system trust module.

Abstract: An information processing system is provided. The information processing system comprises: an information processing subsystem including a processor and a processor support chip in data communication therewith. The processor support chip is operable to provide processor support functions for the processor, and comprises a local management entity. The system further comprises a remote management entity connected to communicate with a remote management network. The local management entity is connected to communicate with the remote management entity via a first management communication channel; and the local management entity is operable to monitor the remote management entity and, in response to detection of an error status of the remote management entity, to divert management communications to a second management communications channel bypassing the remote management entity to maintain communications with the remote management network.

Abstract: A computer assembly for example for use as a network server comprises housing a host processor located within the housing and, a service processor also located within the housing for providing system management functions within the computer assembly. The housing includes a display that is located thereon for displaying the status of components of the assembly obtained from the service processor, and one or more manual switches located on the housing for enabling a user to vary information displayed by the display and/or to alter the status of the equipment. The computer assembly may include a console interface that communicates with the service processor to enable the system management functions of the assembly to be monitored and/or the status thereof to be modified from a remote console connected thereto in addition to or instead of by the display and switches.

Abstract: A circuit module for a rack-mounted circuit has a motherboard detachably mounted in the module for removal and replacement while the module remains in the rack.
