Some bioses will let you set any pnp device with no pnp os (linux)as non pnp device and you will get irq. So if you set in bios your os as non pnp then all you have to do is point your com port to irq used by your modem card there is howto on www.linux.org

Internal modem... If it is PnP, you will need isapnptools from sunsite. If it is a winmodem, give it up. I'm not aware of any winmodems that work with linux. If it is just a jumper setable modem, try going into minicom and seeing if you can get a response form the modem. Try using something like /dev/cua0, /dev/cua1 first... These are com ports 1 and 2.. If you know what com port it is on, just subtract 1 from that com port.. Example. Com 3 = /dev/cua2.. If you get a response. Then there isn't really anything you need to do, except for maybe symlinking /dev/modem to whatever cua#

Sorry to bring you the bad news, but as of now your internal
PCI modem will not work under Linux. I have one of these and
spent a lot of time researching and trying to get them to work.
Finally it was found that you need specific PCI device drivers.
I have a Aopen/Acer 56K and they don't have any driver for Linux
nor are they working on one! Contact your manufacturer (if enough
people bug them, they might feel like writing one :) ). I can't
include all the technical reasons but feel free to explore the
web and you will come to the same conclusion :)
  My solution was to settle for another external modem just for
Linux and now everyhting is OK.

Good luck!!
