Go to the manufacturer's website, and locate your laptop model. They should have copies of all the latest drivers, or at least the drivers that would have shipped with the system.
After much frustratiion not being able to use restore discs on my WindowsXP notebook, I finally was able to re-install Windows, but serveral drivers are missing including the Ethernet. I have used Sisoft Sandra, etc. to try and see the make and model of the ethernet, etc. to no avail. The drivers are on the restore discs which are useless. Generic drivers on Windows didn't seem to kick in. How can I identify the hardware components brand, etc. so I can hit the web for drivers? Thanks.
