These very hard to find modem-driver for a Packard Bell desktop type: Club with a Aztech MSP 3880-W Modem Board modem I found on the Packard Bell site. Instructions: When you have installing Windows 2000 Professional you get a message: installing Simple PCI communications Controller, this fails because Win2000 have not the right driver. You must install this driver, when you do this, you get a message: this driver not work fine for this hardware, will you continue Yes or No, klick anyway for Yes, then you will see,that it will works anyway , you can see this by the diagnose utilities of the Modem.
Good luck. (sorry for my English, come from Netherlands)
