OK, more info. It seems to be a problem with ClassicWB ADVSP. I can boot from a workbench 3.1 floppy, and it shows over 20 meg fast memory free at the top, and 2 meg chip memory free. If I try to boot it this way with the HD and ClassicWB, I get the software failure, and rolling re-boots. The funny thing is, also, if I run GVPCpuCtrl FASTROM, which is the later version of SetCPU, it tells me I must have an 030 or 060 accelerator to run that software. But, when I do get ClassicWB to run, without the A2058, using the Combo Card's ram only, it says ECS 030 at the top. It is weird. Of course the manual that I have isn't right, so this probably isn't the right software for this card, either. I think this is a strange version of the card that isn't common or something.
