A new customer wanted me to upgrade their Vista Home Premium 64 bit custom built system to Windows 7 Pro. I plugged the system into my internet and it worked fine; I upgraded to Windows 7 HP, then did the Anywhere upgrade to Win7 Professional. However I now cannot connect to the Internet thru the wired connection since the Ethernet driver is missing - Windows cannot find it and I have no other documentation other than it is a Zotac motherboard. I contacted them and they said they need the number off of the motherboard (on the bottom of the mb) - this is crammed into a very small case and i can do that but would rather not to - would be like open heart surgery. I have tried dxdiag, windows information, belarc to get the motherboard information to no avail. The person that built the system is not around and the customer has not documentation or CD's - any help???
