There are a few lines below in the default case that may have some meaning,
so it is recommended to test it on one of these machines before fixing it.

So I *netbooted* the VAXstation 4000 m60... You will notice that the on-board network is not recognized. :/

Network appears about every other boot, but I cannot see a clear pattern when.
Don't know yet if this is related to the discussed bug.

With network, add between vsbus0 and dz0:
