Seems that every time I add something new to my A4k it throws up a new and difficult issue!
The latest one: Bought a Cyberstorm 060 Mk1, since fitting it it will take a few resets to display through my Cybervision 64/3d. Once it's displayed it is fine until a power off (resets are fine). Also, if I try to change the screen mode the Amiga crashes to a software failure.
I thought I may have a software problem, so did a clean install with WB3.1 - installed latest 060 install disk from phase5's website - Installed Cybergraphx 4 and it has the same problem leading me to believe it's a hardware issue.
If I remove the 060 and fit my A3640 (clocked at 33mhz so jumpers are set to EXT) everything is fine and fixed.
Now, it has a Buster Rev9 and I've read about Zorro issues with accelerator cards above 25mhz on this revision.
Can anyone confirm that it's a buster issue or have I missed some thing? your advice is welcome as this money-pit of a machine is turning my hair grey(er).

Every new piece adds up the instability and complexity of the system. Sometimes I get the feeling certain mixes of zorro- cards is the evil. Ive had similar problems on my A4000T at times, I remember certain setups would require 3 - 4 soft reboots to get everything ready.

*bump* anybody experienced this?

Have you tried letting it idle at powerup to warm up for a few minutes and then reset? This sounds pretty much like a warm-up issue with marginal signalling somewhere. Can be extremely hard to find...
You may be able to get an improvement out of a (generally but not always) more stable Buster 11 but then again you'll only know once you've tried. I wish someone would make a decent, fast Buster replacement but that won't happen. You've tried moving the Cybervision to another slot, haven't you?

@Zac67 I see your point but it doesn't explain the crash when switching screen modes. Yep tried both slots with the Cv64. I'm fairly certain the issue is down to the cyberstorm being present but the cause...?

I ran a buster 9 4000 for many years with no troubles, but in your case it may be the cv64/3d that needs buster 11. I am not sure if the card had a workaround for buster 9. The accelerator issue you mention i have never heard of. I have run most of the A4000 accelerators available on buster 9 with absolutely no problems. It would probabaly be wise to upgrade to 11 in any case.
You might want to also pull the 16MB of motherboard ram,as it is slower than accelerator ram and can slow down the overall system a bit if you get into this ram early. many things could cause what you describe, bad ram,weak power supply,bad software install(are the dummy libs and all correct?).Check that the chip ram simm is seated and contacts are clean on its socket and simm.

Ah-ha! seems I've fixed it. So for anyone else who has similar issues-
Installing the CyberGraphX4.3 update fixed the temperamental boot display but not the changing screen modes problem. That was sorted by unchecking the 'memory protection' box in WarpOS in preferences.
I'm just surprised that WB3.1 gave me the same issues but there we go...

Slightly off topic, but I see you're from Cleethorpes - You could pop into the Lincs Amiga Group meeting on Saturday 2nd June, we might be able to help :-)
