What do you need to know about free software?

I am working on a Dell Inspiron 5100. I install the operating system Windows XP Home from a Dell OEM CD. I then install the R50830 Chipset Mobile Chipset Driver. (Dell service has told me that I should install the R96945Dell Notebook System Software before the chipset. Have tried both). From what Dell themselves has said, graphics driver and audio driver are the next in line. I have installed the R66756 Video ATI mobility M7 Driver Version A02 and the R90698 Audio Driver. Everything goes well. Next in line is the Ethernet and Modem drivers.
I install the R54627 Network Broadcom 440x 10/100 Integrated Controller Diagnostics Version A01 and the R54631 Network Broadcom 440x 10/100 Integrated Driver. And I am still left with a yellow mark on the Network Controller in Device Manager and no connection to the Internet through the ethernet cable.Dell
I have talked to Dell Support and even though they do not always agree on the order of which the Drivers are to be installed, I have tried different ways, but stayed with Chipset first and the network drivers afterwards. Dell has also confirmed that these are the drivers to install.
I have also tried installing the operating system several times, with different CD`s, downloaded the drivers from Dell Support on different USB flash drives in case of corruptions, but I am running out of options.
Does it matter which of these, R54627 Integrated Controller Diagnostics Version A01 and R54631Integrated Driver, that comes first? Even though Dell says these are the correct drivers, could they be wrong? What is wrong?
I know I have to be doing something wrong, but I can`t figure it out. Just to mention it, the network drivers are installed correctly, but their properties on device manager says the drivers are not installed.

Any advice?

Tomorrow I will try Driver Magician to see what unknown drivers pops up, and see if the drivers need to be installed from the vendors websites, but this should not be neccessary.
