I cobbled this together and it works.
What it does is install the Win2000 drivers on XP by altering the registry
1/ Unzip the files into a directory you can remember.
2/ Click "fixwinxp.exe" (this alters the XP registry to Win2k).
3/ Select your installation language.
4/ Click on the OK button on the "dialog box" that appears.
5/ In the next window "please choose the Windows 2000 driver" Navigate to the folder you unzipped your files into.
6/ Select "web.EXE"
7/ Choose your installation Language.
8/ Reboot after installation this is important as the "fixwinxp.exe" program needs to "re-set" the registry to XP from Win20
