Model: Updated Modem to V90 from Sporster 56K
Operating System: All Windows 98 (Note: might work with other versions of this os.)
The driver also includes the update for the original Sportster 56K from X2 to V90.
To update it is up to you, your modem will be a little faster, but you must be carefull, 'cause the older driver won't work, so keep this ".inf" files.
If you have any doubt ask me
