Abstract: In an aspect of the present invention, a computer system includes a plurality of computer nodes and an inter-node connecting unit configured to connect the plurality of computer nodes. Each of the plurality of computer nodes includes a local memory configured to store fault data of the computer node and a main memory. When a coupling command is issued to the plurality of computer nodes to build up a multi-processor in which the plurality of computer nodes are coupled, each of the plurality of computer nodes writes the fault data of the computer node in a predetermined address of the main memory of the computer node.

Abstract: In ROM is stored a firmware having steps of: obtaining from PCI devices which are mounted at the present moment, information regarding to size of resources to be required; obtaining by input of user, information regarding to size of resources to be required by PCI devices which will be mounted on in the future; and allocating resources for PCI devices with adding up above mentioned both capacities of resources. In main storage unit is stored a software having a step when PCI device is newly added on while the system is under its operation, to allocate resources allocated for peripheral devices which will be mounted on in the future to PCI device newly added on. CPU executes the firmware at Start up process and executes the software when peripheral device is added on while system is under its operation.
