XP Drivers! !

I have just purchased 3 Sony Vaio VGN-FZ19VN laptops, under the impression i could install XP Pro quiet simply. After a few problems i managed to get XP on the machine, however when it came to installing the drivers that was a different matter! I downloaded the drivers supplied by Sony inly to find they wouldnt work with XP, i then found the drivers for XP on the USA e-support site, but when i went to install them i got an error message saying that the drivers were not for my particualr model!! If someone knows where i can find the driver please let me know as i have my mamager breathing down my neck wanting to knwo why our new sales persons doesn’t have a laptop!! Thanks in advance
