Switched hardware now os wont start Modem

Greetings-

I bought an IBM Thinkcentre (2.6 GHZ, 500Megs ram) and switched my Nvidia card, hard drive, cd & dvd drives over from old machine & hooked up modem to new machine. So far I have had two issues. When I booted new machine up, it came up in text mode only. I was able to work around that by running "sax2’, solved that in a hurry. Second issue though- I cant get my modem to initialize. I have tried to reconfigure it w/ YAST, and the system knows its there. The lights change as its working through the setup, but it doesnt want to initialize. Any ideas?

Thanks for your time.
