Common Problems and Solutions
10/100/1000 Gigabit Network Adapter
11.The workgroup, protocols, cabling and driver are all working properly, but the PC uses an AMD
processor and it can only see itself in the Network Neighborhood.
In some instances with PCs using AMD processors, the IRQ assigned to the Adapter by the BIOS—as it gets
listed on the boot-up screens of most PCs—doesn’t correspond to the IRQ assigned by Windows. This can be
fixed by disabling the IRQ holder for PCI Steering in the Windows Device Manager. Refer to your PC’s
documentation for instructions or follow the suggested instructions below. (Keep in mind that this procedure
will vary depending on your computer’s configuration.)
1. Click Start, Settings, and Control Panel.
2. Double-click the System icon.
3. Click the Device Manager tab.
4. Open System Devices and PCI Bus.
5. Click the IRQ Steering tab. Remove the checkmark from Use IRQ Holder and click the OK button.
6. Windows will ask you to restart the computer. If it doesn’t ask you, then reboot the computer
manually.
7. After the computer boots up, Windows will try to re-detect the PCI Steering. Continue rebooting the
PC until Windows stops detecting new hardware and settings for PCI Steering. This normally takes a
total of four reboots.
