Thanks for replying. Before I read your post, I removed the modem because I didn't need it, and the NIC. Removed both from device manager.
Rebooted several times and now trying to add the NIC back in. Box is seeing the NIC but not letting me specify the driver and add it in. I told it to " show me a list of all devices" blah blah blah and then was able to specify the driver location. But then Windoze pops up "Windows was unable to install the 3Com OfficeConnect ..."
By taking out the modem and the nic - the PCI Serial Controller thing went away.
You'll need the driver/controller for the PCI Bridge for that particular system. Check Sony's web site for you particualr model and download system board/controller drivers and that should resolve the problem (after a reboot of course)
