I open up Poseidon and I still get 'unable to open openpci.library' 'OpenUSB.device failed'.
I am now running OS3.9 with BB1&2 on a BlizzardPPC so maybe there are some Mediator variables that I need to change? What are your variables in prefs:env-archive/mediator/? Do you have the spider USB driver installed (I don't)?
How did you set the memory window jumper? 8 MB? You might try changing it to different values, e.g. 0MB. As far as I know the "hackish" memory window is one of the differences between A1200 and A4000 Mediator.
