I read the other postings, but couldn't find the answer about the problem what I have.
A friend of mine has a Power tower with an A1200 motherboard and a standard ELBOX PSU. Blizzard 1260 accelerator card with 32 MB of RAM .It has an Zorro 3 busboard. I don't know the revision numbers of these boards. He has fitted a Auraplayer in de PCMCIA slot. An Elbox 4xEIDE\'99 Buffered Interface with two cd-roms and two harddrives.
A Cybervision 64/3D graphics card and an Ariadne II network card.
He also put AmigaOS 3.9 over OS 3.5 installation, that causes the problem. I warned him about this problem.
The following symptoms:
-Doesn't boot even without the the IDE stuff or Zorro cards.
-Sometimes it's possible to get in Workbench, but when an icon has been doubleclicked, The computer reboots.
-Even booting workbench from disk has also this problem.
I think that the problem is the Zorro board. I heard that this boards has som mechanical problems. What are these problems?
