nex4060 : the modification is only needed when using scsi on the Cyberstorm and that module is not connected ..
X-ray : thank you for your offer but I already have the real manual but it doesn´t help me out ...
MrZammler : "Anyway, apart from the jumper settings, 040/060 cards require roms 3.0 or 3.1 IIRC to work. (Wont work with superkickstart images)" ... true, there is no kickstart rom inside, though the computer boots up with kickstart 3.1 (V40) in its memory. I found out that this rom-file is placed in the Devs directory and it seems to load that automaticly without an extra line in the startup-sequence. May this be the problem ?? As I said before, I do see the coloured bars that are typical for the Cyberstorm, so I thought I was doing well, but I didn´t get any further than that ... if it is so that I do need a real kickstart rom (there is an empty space on the motherboard for two roms) then this may mean that the card does work but that my A3000 is not yet up to it :-) Please correct me if I´m wrong :-o
