I did essentially the same thing, although I modified a 1006V-MM1 for the alternate interrupt and address. I tried it with a Seagate 4051 (40 meg drive) and had the identical problem. I think that there is something in the controller card (my guess only) that may be dying. I did notice that when the system died the drive hooked up to the second card was permenantly selected (I had the drive led on the computer hooked up to the second controller card, and it went on and stayed on.) My feeling is that this seemed to occur during periods of heavy io. If the Adaptec card works could you let me know? JB -- Jonathan Bayer Intelligent Software Products, Inc.
