Weird CyberVision PPC issue (duplicate entries in the EarlyBootMenu/Boards)

[Robert17]

Welcome to Amiga.org :pint:  :pint:  :pint:

I think it's normal to have a few entries in the autoconfig space for a Cyberstorm III - I'm not sure if plugging the CVPPC card in would make much difference, as it's on the PCI bus and not in the Autoconfig space, but I'm not sure, my setup is broken so I can't check :-( I wonder if 3.1 is crashing due to not having the proper Libraries installed, have you done a fresh install?

A Good way to test system stability is to not load anything, just leave it sitting at the insert disk screen and see if the animation keeps running, if it doesn't, you know there's a definite hardware issue somewhere.

Can you post in what shows in your Early boot menu board listings, so we can have a look :-)

Have you tried testing with the original 030 CPU board?

Also, if you have, or can obtain a voltmeter, maybe you could check if the PSU voltages are correct.

The instability issues could still be a result of a bad PSU. You can measure the voltages whilst the machine is running by putting the probes into the A4000 PSU plug, there should be a small gap so you can get a reading. You'll know if it's knackered if the volts are too low.

A4000 PSU pinouts can be found at:
