Cyberstorm MK3 scsi issues
« on: June 20, 2005, 03:54:00 PM »
I had been using my Cyberstorm MK3 system for a long time with a Prometheus PCI bus (with Voodoo3 as graphics card) and an A4000 Desktop (in a tower).  I also had attached a 9 gig seagate barracuda scsi drive (68-pin Wide drive).  No problems at all.

Then, I took out the voodoo from the prometheus and put in my Cybervision PPC card (that I hadn't used in awhile, and probably never used in conjunction with the SCSI controller on the cyberstorm).

I am now getting alot of error #8000004 when starting up the machine, or if I try to boot from a Workbench 3.1 disk I get RAM has failed again with 80000004 error.  A *few* times I have been able to get the machine to boot into basic Workbench 3.1 from the floppy and I can see the SCSI Disk partition (my old workbench partition), and I can see the files on it and it appears to be fine.  But rebooting I get that error again #80000004...

Now... I am overclocking the 060 chip to 66.6Mhz.  But I did the modification with the jumpers and the oscillators that should have ensured the SCSI works fine with the overclocked 060.

(Yes I am using a heatsink and fan cooling and the machine is in a cool basement, so heat should not be an issue)

If I remove the cybervision PPC card the scsi is properly recognized and I don't get the error #80000004.

Has anyone else seen this? Am I getting this error because my 060 is overclocked?

The modification was done based on Dave's Overclocking page which was here: http://www.starnet.com.au/davem/amiga.html

But now seems to be offline...

They are all 60ns modules which I had been using with no problems (without the cybervision attached)...so I'm not sure it is ram, but I can definately take some ram off to see if it makes a difference.  It has 96MB of RAM on the cyberstorm.  It is a 60MHz 060 as well, so overclocking to 66Mhz has never been an issue for that cpu.  I will also try the pre-charge option...
