You can download the driver for the Second Edition of Windows® 98 (Win98E) from the driver download section here
. There is however no way to get Flash Drives working with the First Edition of Windows® 98 (Win98 - a very old and uncommon operating system so no driver has been developed).Most USB Flash Drives
use mass storage class drivers. These are included in Windows® ME, Windows® 2000, Windows® XP® and Vista®. Therefore Flash Drives are 'plug and play' with WinME®, 2000®, XP® and Vista®.
