A computer main unit and a PCI_Box (#0) are connected to each other in a loop connection manner by two paths. A first path is formed of an SMBus and a PCI_Box connection cable and a second path is formed of another PCI_Box connection cable. A monitoring and control unit (MMB) recognizes a connection path by reading out, through the second path, connection setting information written to the PCI_Box (#0) via the first path.
