Mea culpa; a better word would have been "startup." Our 10M takes a while to come to ready status, and rather than watch the sliding Apple, we just leave the CPU off until then. BTW, earlier this week I upgraded my GS with a TransWarpGS v1.5 and a Hi-Speed/DMA SCSI card, and've been having no end of trouble trying to sort out what has since been randomly crashing the system. I've just read another posting of yours about DMA problems with older GS-Ram cards, and since my GS-Ram is about two years old, I'm now suspicious of it, and want to check it out tomorrow (and call AE). Do you have any more info on how to distinguish a problem GS-Ram besides flicking the DMA switch on the SCSI board?

I don't, but perhaps some other reader does. (Probably some patch wiring exists on the DMA-comp0atible GS-RAM, or something like that.) If the system works solidly with the DMA switch off, and reliably flakes out with it on, that's pretty good proof of a DMA-related problem..
