The only way I would be able to answer you on this one would be if you would supply the make and model of the modem.
If you do not know that info (bare modem you got from a friend for example) then take readable photos of all the labels and markings as well as one of the front and rear surface of card and upload them to a picture hosting site such as:
... and then ask me another question containing links to the photos. I will see what I can find out for you.
What I can tell you about installing your modem without seeing it is this: If it is a software based "winmodem" then the drivers will be needed. No exceptions save for those built into WindowsXP or above. If it is a hardware modem, then drivers aren't usually required, and they practically set themselves up in XP or better.
