... while we are at that... Hab beim Suchen nach den Infos zum L1-flashen ein kleines Howto gefunden das ich vor Ewigkeiten mal für mich selber gemacht hab, ich weiß nicht ob das hier schon mal gepostet war, nochmal kann sicher nicht schaden.
Bei der Origin 200 hat das PIMM kein eigenes ROM, die Daten zur CPU werden im Flash auf dem IP29 gespeichert, darum kann man hier die CPU nicht einfach durch austauschen des PIMM's upgraden. Zusätzlich muss das PROM mit den Parametern der neuen CPU geflasht werden. (Logisch ist eine O200 soviel wie ein einzelnes IP27 Nodeboard mit aufgelötetem IO6 und PCI-Bridge)
ACHTUNG: Der hier beschriebene Vorgang ist nicht ungefährlich! Beim kleinsten Fehler kann das Mainboard unbrauchbar werden! Anwendung auf eignene Gefahr!Upgrade einer O200 mit R10K-180 2MB Cache auf eine Dual R12K-270 4MB CacheLog vom Flash eines Dual R12000 270MHz 4MB Cache:m1 MotherBoard: Flashed this prom 6 times

... damit hätten wir die nötigen Einstellungen für den R12K-270...Erstmal wird das PROM 'normal' neu gefalscht, nur um ein 'Backup' der nötigen Parameter zu haben um das Board ggf. retten zu können.IRIS 2# flash -o

Jetzt wird das PROM mit den Parametern für den neuen Prozessor geflasht. ACHTUNG: Wenn man hier was falsch macht ist das Mainboard UNBRAUCHBAR!!! [IRIS 3# flash -fo

Jetzt die Maschine runterfahren, dann das Prozessormodul tauschen, Maschine wieder booten und hoffen...
Beim ersten Hochfahren mit dem neuen Modul muss der zweite Prozessor noch manuell aktiviert ('enabled') werden.Hier mein Log der Konsolen-Meldungen:
