I installed XP pro 64 on a partition of my multi boot system which also runs Vista and W7.
The XP install completed, but there is no internet/network connection. Network adapter properties says it has a driver, and is working properly. Status shows zero packets sent or received. If there is additional info that may be helpful, I will check next time I am in the system.
XP was installed after Vista and W7; not sure if it makes a difference with network connection..
Motherboard is Abit K9SLI. I checked Abit site for drivers and they have an XP64 chip set driver available, which I download and it a corrupt/empty .zip each time.
