|I got my 7GB Cruzer working flawlessly in Win98SE even though it says it requires 2000/XP.|
All you need to do is download and install NUSB. The program files will automatically be extracted to the proper folders.
Then reboot the computer and stick your flash drive in the USB port.
After you insert the flash drive and it goes to look for a driver or Win98 CD-ROM, just keep hitting next and it will automatically load the drivers (they have a stamp of 7/11/2006.) You don't need the Windows CD because the needed files have already been extracted into the proper directories.
