Which INTERNAL modem do I have ?
This page is intended to help you to identify which internal Modular Technology PCI modem you have, and lead you to the appropriate page for drivers and FAQs.
Firstly, note that this page only covers PCI cards – these have an edge-connector which is 79mm long (3.1 inches).
If you modem has a longer edge connector, then it’s an older generation ISA card,
look for drivers here and FAQs here.
For PCI cards, if you look closely at your modem, you'll invariably see a single chip (Integrated circuit) which controls the modem. This chip and its code numbers determine the modem type.
