Thanks for the suggestions. To get to My Computer I'll need to reinstall windows. Sort of a pain. It takes about an hour to install. Don't see another choice, though.
I thought I didn't install the drivers which are marked "Install SP2 before installing this driver".
Does SP1 need to be installed before SP2? Or is it incorporated in it?
A reinstall of XP followed by SP1 only solved the problem. I backed up with XR-2 to avoid the lengthy installation of XP in the future. Chip drivers will load properly with SP1.
