#Amiga Link problem

Fascinating! (Spak imitation mode). I'll check my masks. I have already
turned off the Trifecta scsi controllers' DMA xfers so I suppose
downgrading it further by killing scsi2-fast xfers won't matter much. Come
to think of it I don't even know how to kill sync xfers on that
controller, I don't think you can.
Thanks for the update

Tom,
Strike that last solution 🙁 I locked up again last night. Maybe you're
right, there seems to be a problem with the Derringer. The A4000 and GVP
accelerated A2000 don't lock up. I'm going to see if I can figure out how to
restrict DMA to only chip ram on the volume I share out (on the Derringer
equipped A2000). How are you configuring the Derringer software? I load the rom
into fast ram using their MMU-less technique. I'd hate to have to disable all
the speed enhancing options I have on that machine just to prevent these
occasional lockups 🙁

I am currently using the old tried and proven CPU command to load fast ram
on the theory that the mmu-less thingy could be bad. No help. I am using
the derringer D3 command with only the DRAM option to bring the 32 bit
memory online.
I never did get the masks on my drives changed, the format/partition
software from ICD for the Trifecta doesn't let you do that and I am still
trying to figure out how to make HDtoolbox do it. (got it to accept
trifecta.device but afraid of wiping out my whole system with it). I do
feel it is a scsi bus lockup problem in my case because on occasion I have
had one or another drive light locked on and the thing frozen up. I have
to turn power off the drive to get it unhung. Never had that before.
Frankly I have been too busy durng the day to call CSA and seek assistance
with it but if my BBS stays down much more I may have to give up and yank
it. Only thing I can think to do at the second is to swap in a
nonbuffering non-DMA ICD2000 controller for a while and stop using any
fast-rom option at all. I will try that tonight.
