Symptom The Ethernet Controller cannot connect to the network. The Configuration/Setup Utility program reports the Ethernet controller interrupt Utility as 0 or 255. The PCI BIOS is not configuring the Ethernet controller or adapter correctly. The Configuration/Setup Utility program reports No PCI Bus. The Configuration/Setup Utility program has been run on another computer that does not have any PCI slots. The server stops running when loading device drivers. The PCI BIOS interrupt settings are incorrect. The diagnostics completed successfully, but the network connection fails. FRU/Action 1. Run Diagnostics 2. Check Cables 3. System Board 1. The PCI BIOS interrupt settings are incorrect. Check for interrupt conflicts with ISA devices. If conflicts are found, reserve the ISA interrupts (see "ISA legacy resources" on page 36) so that the PCI BIOS will assign another non-conflicting PCI interrupt value. 1. Run the Configuration/Setup Utility program on the server so that the PCI BIOS will configure the Ethernet controller or adapter correctly 1. Check for interrupt conflicts with ISA devices. If conflicts are found, reserve the ISA interrupts (see "ISA legacy resources" on page 36) so that the PCI BIOS will assign another non-conflicting PCI interrupt value. 1. Make sure that the network cable is securely attached. 2. Make sure that you are using Category 5 cabling when operating the server at either 10 Mbps or 100 Mbps. IBM Netfinity 3000 - Type 8476 195
