I started with a fresh hard drive, did a full format, installed os 3.1 and idefix to get the cd drive working and then installed os 3.9 from the cd I had purchased from Softhut this summer. One possible problem occured to me today.... the tower uses a Cyberstorm 060/ppc. I installed the os 3.1 software from my friend who sent me the tower and not the Phase 5 software because, in part, the install disk had a note scribbled on it indicating it was modified with the '060 library. I figured it was the OS the tower had arrived with so it would probably run the Cyberstorm. (Why the original HD is not being used is another story...) I suppose that the 3.1 software might have left something "different" behind that the OS 3.9 didn't remove...? or the Phase 5 stuff being not there might somehow interfere with Preferences? The trouble with that thinking is how would I know and why wouldn't the 3.9 stuff override the 3.1 legacy software? Maybe I should install the Phase 5 software and see what happens. The desktop model with 3.9 on it runs mostly fine and IT only has an '040 board. Hmmmm. Sounds like it has to do with the Cyberstorm, nes pa? Man, I hate to start all over again. Everytime I get this thing running right I find a problem or create a problem and then start all over again. I still can't make the damn thing boot with more than one hard drive attached! Yeah, I'm that incompetent. But I am a very good sculptor and I build very nice wood fired kilns, so I got that low tech stuff going for me.... 8-)
