    I don't know if you ever got this figured out but I had the same issue. In quite a few different threads, machinetek suggests removing the BMDC board and cleaning all of the contacts with a pencil eraser. He also suggests moving it to a different ISA slot if possible. I did this and it worked straight away.
    Give her a go and let me know what happens. It sucks to read through threads that have no resolution!
