Finally I can contribute to this site which I say is a FREE blessing. This DELL Modem when installed is listed under the Device Manager as a Conexant HSF V92 56K Data FAX PCI Modem. The Conexant Chipset is labeled with RS56-PCI R6793-15 E206156.1 0214 MEXICO It might vary on the modem but it should at say R6793-15. Please note some Windows 2000 drivers can be installed on XP sucessfully and work. I have not tried this driver with XP but drivers say it should work in the documentation. You all have a nice day.
