Received the follow messages:
1) No official 'Cisco' drivers, but I've had luck using the beta Intel 2100 drivers. (Same chipset & board design)
Download drivers
2) The current result posted that says that the Intel drivers work for the Cisco modem did not work for me. When I tried to install the drivers for it, I recieved the message that it was not a compatible driver and Windows did not accept the driver. Current status is that the Cisco does not work in Win2000 unless there is some driver editing that gave the previous user a working result.
