Södale, ich habe nun einfach schnell ‘ne Pizzaschachtel (FSC Scenic Xs) installiert, die hat noch die guten alten RS‐232-Ports, an die ich meinen Conrad C-Control-Programmer dran hängen kann, der letztlich mit den Zugang zur seriellen Schnittstelle des DockStar liefert. Und was sehen meine entzündeten Augen?

Nunja. Nicht schön, aber …

… noch scheint nicht aller Tage Abend zu sein. Ok, der nächste Schritt wird jetzt etwas dauern, denn nun muß ich wohl mich erstmal ein wenig einlesen, wie ich diese selbts beigefügte Scharte wieder auswetze ;) (Interessant, daß es ein »Cloud Engines«-Board ist; hat Seagate also echt nur dazugekauft? Witzig …)
Oh. Das scheint ja simpel zu sein:

Das waren dann erstmal die letzten Worte; mal Ethernet ankabeln, ob die Box da gesprächiger ist.
