I am new with linux, in the past days I installed Mandrake 9.1 in my notebook (Compaq Presario 3000) but I can't configure the Firewire and modem card, so I never visited the internet using linux

.
Ok, under Windows XP I can connect both computers using a Firewire cable sharing the Internet Connection, printers and files of the desktop with the notebook. Mandrake identify the notebook's wireless and ethernet Lan cards but the modem and the IEEE-1394 dont have the same luck ;(
I hope that you can help me, pleaseee !!!!!!!!
