Error on chipset driver install (and thus others??) following windows 7 enterprise clean install on mx11

Hi, just bought an alienware mx11 which shipped with windows home premium (japanese). Got a copy of enterprise (Japanese 64bit) from work and so decided to go for a clean install of the superior OS. Went to the dell drivers and downloads and entered service tag of machine prior to install. Put all 21 files on a flash drive. Performered the clean install. Problem: When attemptung to install drivers in the order given in related article-- i.e. Chipset first etc. I get an error message saying something like "the system is not set up to handle this driver" (bad translationn of the japanese error) across several key drivers. The chipset driver itself doesnt seem to process. Graphics drivers too. Some drivers work (audio) but i cant even get the internet up and running--which driver gets me the internet controller?? Please help!!
