This is the NEW driver for the Rockwell chipset now being manufactured under the name Comexant.
This modem is fully PNP,however,when installing be sure to disable Serial Port 2 (COM2) in your BIOS. If you find that your having problems still,
try resolving IRQ conflicts my moving the modem to a different slot (remove sound card and reinstall it after the modem). If AGP is installed on the mother board a conflict may exit with PCI IRQ steering. Try adjusting the source of the system resouce drivers for windows in Control Panel/System Properties/Device Manager/PCI Bus Properties/IRQ Steering.
