HP Notebook Modem Installation If you have an HP Notebook equipped with an internal modem you will need to identify which modem was supplied in order to install the appropriate driver. Your HP Notebook contains either a 3Com 56K V.90 Mini PCI Modem (combo) or 3Com V.90 MPCI Modem 556B (modem only). If your notebook is equipped with both a LAN port and a telephone jack you have the 3Com 56K V.90 Mini PCI Modem combo card and should use the drivers found on the HP\DRIVERS\\MODEM\PCICOMBO directory on the HP recovery CD. If your notebook is equipped with only a telephone jack you have the 3Com V.90 MPCI Modem 556B Modem only card and should use the drivers found on the HP\DRIVERS\\MODEM\PCIMODEM directory on the HP recovery CD. If your notebook is not equipped with a phone jack, then a modem was not supplied.
