Well here is the update.
I removed the floppy and cable from a known working system and tried them...I got a different error. The system configuration was incorrect. The cable from the other system was very different than the cable being used in the system I am working on. The system I am working on has 3 small connections; one at each end, and one in the center. But, it also has one very large connection. The cable I removed from the working system only has 3 small connections. I am beginning to think it is the motherboard. But if that is the case, I wouldn't be able to read and write to the drive in windows either. right???
