Linux on G4 -> Network-Problem

Hello, I've got the following problem: I just installed Linux on my PowerMacintosh G4 (2x450). It acutally (after some hours of setting it up...) works fine, but I can't do yet a network connection to my cable modem, because of the fact that I don't know, what card I have to specify in the menue, where I can choose the type of my network-card: It gives me a list of many cards (3Com 3c501, AMD Lance...etc), but I don't know which one is the correct one. Does any body know which network-card is installed on the G4? With best regards Matthias Geissbuehler
