In Figure 1, the Vender ID is "1022" and the Device ID is "2000".
If you are using the latest version of CCBoot, you can also obtain such VEN/DEV ID directly via CCBootPNP tool. In the CCBootClient install folder, you can find such tool, launch it and then it will show you the PCI Vender and Device ID of the current network adapter (NIC).
