"no link beat found" on digital alpha-station 255

[Cornelius Weiss <weiss@physik.uni-siegen.de>]

Hi list,

i managed to install a debian-base-system from the net-install image on 
a digital alpha-station255.
After the reboot of DI the installation couldn't be finished, as the 
network isn't working.

On colsole it alwas says: "Wanrning: No link beat Found"

Is sombody aware of a solution for this problem?
