Most generic drivers should get the laptop working and on the internet. When it asks for a file, or driver you may have to manually point it to the files in your setup files. Then go online and get any updates.
Alternatively with Windows 98 you can install on one machine then move the drive from one computer to the next. In the new machine Windows will boot and look for any new drivers it needs.
Also I think you need Windows 98 SE (second edition) for USB to work natively. Otherwise you will need to search and download a USB driver.
may be a good option for you also.
