Problem with Cyberstorm Mk-I

[mechy]

I have a Cyberstorm Mk-I 68040/40 for my A4000D. This machine also has a fully loaded memory module that decided (for some reason) to stop working today.

It simply no longer appears in the list of expansion boards and my machine went from over a 100MB to to the stock 18MB (16MBFAST+2MBCHIP).

I have removed and reseated the module. Does anybody else have any ideas or utilities to query the RAM module?

I am not that familiar with the MKI other than i recall it has the funny extra ram board etc. Is there a chance static got the ram on it? You don't mention how much ram there is,but if 128MB this seems unlikely.
have you done anything to disturb the accelerator lately?

So, I took a closer look at the jumpers on the Cyberstorm MkI. There is a memory jumper noted as JPA in the manual. It says that 1-2 is normal, 2-3 is fast and open is slow. I thought perhaps I could change the jumper and get the memory to be recognized. I pulled it out of my machine and took a closer look.

I was wondering if I should bother with this or not. Any thoughts?

The manual says:
If problems arise with the memory (e.g. it becomes obvious that previously perfect programs such as Lharc or other packed archives now contain faults), the JPA jumper on the CYBERSTORM carrier board must be changed. This increases the tolerance to memory modules with too high a capacitive load (these are only occasionally on the market, but cannot be differentiated from other types). If problems still occur after this then please contact our technical support centre.

You could try it as a last resort, but i suspect since your ram quit working all of a sudden that something has went bad or a bad connection somewhere has developed, but your guess is as good as mine as to where that could be. sorry i can't be of more help.
