Do you have a MB install CD? Drivers should be on there?
If you downloaded an updated version, do you know where you saved the download? I don't know if you will be able to find out all the files and find them after they are intsalled, but maybe you can e-mail your MB company and see if they can give you a list or something?
Or, maybe you can post the version you have and someone with a faster connection can download and see if they can determine the individual files (like if it comes as a zip file of something).
-D'oh!
