It's the operating system that has the driver support.
IMO, XP has excellent driver support for older systems...I'd just try to install XP and see if it comes up with basic drivers for the system.
Make and model of the laptop?
As slix suggested, it's still a good idea to download the drivers before doing the XP clean install. But, if one has two systems, you can just make the clean install and get the drivers anytime on the other system, if they are needed.
