This is the driver for the Belkin PCI network card that says P/N 141211-427 reb. 01 on the front of the card just below the large chip labeled MPX. This driver should work with Windows 98/ME and 2000. Information for XP, go to www.belkin.com, click onm Support and type F5D5000 for the model number. The card also says N10117 so hopefully this will help in aiding a search for this otherwise unlabled card with no FCC ID.
