ABSTRACT:
A system management module (SMM) for a host server system includes a system management processor (SMP) connected to a system management local bus. The system management local bus connects to the system PCI bus through a system management central (SMC). The SMC includes the main arbitration unit for the PCI bus and also includes the arbiter for the system management local bus. The SMM includes a video controller and/or keyboard and mouse controller connected to the system management local bus to support remote consoling of the SMM. The video controller is further used for transmitting screen images to a remote computer system to facilitate system failure analysis. A plurality of system management remote units are provided for coupling to various components and busses within the host computer system. The system management remote units (SMR's) connect to the SMM via serial bus and permit the SMM to automatically monitor activities and operating conditions, including determining the source of interrupts on busses and detecting error conditions.
