no ethernet card detected

Hello, I am trying to do a new installation of Debian 6.0 on a Dell Optiplex 790 computer. The graphical installer does not detect the ethernet card and hangs. The actual ethernet card on the machine is an Intel 82579LM. Does anybody know a solution to this problem? Thank you very much. Geoff
