A4000 problems.
Hi,
I just got an A4000/60 and I have some issues , some of you maybe read about it on amibay. System specs: Cyberstorm Mk1 060/50 64mb RAM & SCSI controller Cybervision 64 gfx card DKB3128 with 128mb RAM Deneb USB Indivision AGA scandoubler SCSI CD-ROM drive on board 2MB chip ram (no fast ram memory). When I turned on the system for the 1st time, I had reboots and sometimes a green screen between them. Then I unplugged everything (zorro cards/daughterboard) and managed to boot the system with the 060 without its ram-module. Putting back the ram-module causes yellow-screens+reboots, I tried a lot of combination with the SIMMs (DKB3128 has 4x32MB, CS module has 4x16) on the RAM module, but in vain, only get reboots+yellow_screen. Also, there is no way to boot to the system when the CyberSCSI is connected. I get just a black screen. Could this possible because there is no RAM module on the Cyberstorm? Also, do you think that the ram module can be repaired or something like this? Any ideas , please? thanx in advance chris Last edited by xc8; 13 February 2010 at 20:58. Reason: typo.. |

Yellow screen + reboot does also happen if you boot from a disk without the proper 68060.library installed. Can you reach the early startup menu and boot without startup-sequence ?

the HD does not even boot when the ram-module is installed. pressing both mouse buttons does nothing, as the system just reboot.

I still think on a bad PSU. Please check the +5V power rail.

Its 4.90, when I put the ram_module is the same.
But when I don't connect the PSU on the m/board is 4.98! chris |

8512 = Phase5 : 34 = Cybervision64
2012 = DKB : 14 = 3128 3643 = E3B : 16/19 = Deneb (although AHD lists as 18/20) Take out the DKB 3128 and see if that fixes it. Last edited by alexh; 17 February 2010 at 00:17. |

thx... now I think I managed to find the problem, the cybervision64 was hot like hell, the DKB was over the gfx card, so I suppose the DKB was in trouble due to the heat.
Now I put a temporary fan (vertical) between these two cards (and moved the deneb to the lowest slot) (gfx is on the top slot now, then one empty slot, then the DKB). I have a thermaltake pci slot fan somewhere, I will put on the empty slot between these two cards. Freakin design of the case, the airflow sucks... chris |

I think we have to close this topic.
All the problems were caused because the ram module of the C'Storm is faulty. Recently I discovered that works only with 4MB SIMMs..! Putting any other size results to a nice yellow screen. The system behaves better now even with a 4MB on the ram module. Chris |

So use just four 4Mb SIMM sticks on it. 16Mb is not a bad amount for the Amiga.
