Product data: Select this choice to view system information, such as the machine type and model, the system serial number, the system board identifier, and the revision level or issue date of the flash electronically erasable programmable ROM (EEPROM) for the system management processor, diagnostics, and BIOS. System card data: Select this choice to view information for the system board and processor board. PCI routing: Select this choice to view the IRQ settings for PCI adapters and for the Ethernet, SCSI, and other controllers on the system board. See "PCI bus control" on page 98 for information about changing the PCI IRQ settings. Devices and I/O ports: Software recognizes ports through their port assignments. Each port must have a unique port assignment. The Configuration/Setup Utility program normally handles this, but you might have special hardware or software that requires you to change these assignments. Note Serial port A can be shared by the system management processor and operating system. Serial port B is used by the operating system only. Management port C is controlled exclusively by the system management processor, cannot be used by the operating system, and cannot be configured using the Configuration/Setup utility program. 92 Netfinity Server HMM
