I'm not sure this is related, but I was having somewhat similar problems with a new fx I had. It booted up OK, but after a short while bad things began to happen. I tried everything I could think of, video card swaps, new disks, reseating the SIMMs, etc. Finally someone asked me if it had NEC SIMMs inside. I looked and it had 4M of NEC and 4M of Hitachi SIMMs. They advised me to switch the two banks of SIMMs. I did this and the fx has worked like a charm ever since! You only have 4M of memory, but check it they are NEC chips. If they are, try to dig up some non NEC chips to try in your machine... -- michael P.S. I know this sounds crazy, but it worked. Are the NEC chips slightly out of spec? -- Michael Peirce -- {apple,decwrl}!claris!outpost!peirce -- Peirce Software -- Suite 301, 719 Hibiscus Place -- Macintosh Programming -- San Jose, California 95117 -- and Consulting -- (408) 244-6554
