Hello sun-managers!

I'm back with a summary.

First, my original question:

There seems to be three possibilities:

a) The obvious one: boot cdrom -s
   Shame on me for not even had tought of it... :-(

b) The similar one: boot cdrom -sw
   Same comment has the preceding one...

c) The one I should have seen: when you're in the installation GUI, you can
   select a cmdtool from the OpenWindows menu or you can exit the installation
   at some points and then find yourself in single user mode.

Thanks again for your help and recommendations. I was overwhelmed by
