Example for Compaq nx6110:
Network is not working, and when following above resolution step by step, in step 15 - when one should find the name of network card, on web pages with the specifications for nx6110 it says that network card inside nx6110 is NetXtreme (10/100 NIC) PCI Express Ethernet Controller. But in registry there is no Netextreme to be found! Actually it is found under Broadcom (search for "Broadcom" in registry), and after resolution, installed network card for nx6110 is actually identified as Broadcom 440x 10/100 Integrated Contoller and not as Netextreme
