Using a Troubleshooting Checklist If you need to test the network card further, check the following items: • Inspect all cables and connections. Check the length and rating of the cable. Make sure that the cable segment is compliant with the requirements shown in Table 2-3 on page 2-8. • Connect the network card to a different network port and run the tests again. If successful, the original network port may be defective or improperly configured. • Check the network card installation by reviewing Chapter 2, "Hardware Installation." Make sure that the network card is properly seated in a PCI slot. • Check for specific hardware problems, such as broken traces or loose/broken solder connections. • Check the configuration settings and change them if they are in conflict with another device. • Make sure that your system is using the latest BIOS. Check the PCI BIOS parameters for proper configuration of the slot where the card is installed.Table 8-2 shows several possible PCI BIOS parameters. (These parameters may not all be available on every system.) Table 8-2. PCI BIOS Parameters Parameter Setting Bus-Master Enabled. Interrupt number Set to any IRQ that does not conflict with another device. Latency timer Recommended range is between 20 and 255.This parameter is typically set to 64. troubleshooting 8-2
