I have a HCF V90 56K PCI modem with the Rockwell chipset. (specifically, the modem was made by Phoebe Micro, and is numbered CMV1456VQHR-PCI).
The modem was working fine, but then I had problems with my harddrive and had to replace the harddrive and reinstall the OS. The problem is that I can't get my modem to go onto COM3 like it was with the old harddrive. It won't work on COM2. I believe the problem is that the HCF PCI Modem Enumerator does not show up under System devices. (It was there with the old hard drive) If I understand correctly, the modem enumerator is what enables com3 for this PCI device. I don't know how/where to add this modem enumerator. I think that it is installed automatically when you install a new PCI card, but I can't get the system to detect my modem as a new card at boot-up (I've tried moving it to another slot, but it's still not detected as a new device ... is there something stored in CMOS that is telling the system that this device is not new?). That's the problem.
