This Driver Works with the HP Pavilion N3350 and should work with other similar aged HP Pavilion N Series Notebooks. This one is an AMD K6-2 550MHz Processor. This driver works with the audio and Modem. HP Has two drivers listed for the Modem+Audio, but only one works with the modem as I found out. So that is why I am uploading it, so you won't have to waste too much time. Here is the name for the modem as seen in the Device Manager
ESS WDM Modem Enumerator
ESS ES56CVM-PI Data Fax Voice Modem
Good Luck, Rock on, People.
