Actually, this way of detecting what disk controllers is a real mess!
I have realized that VS3100 have very different contents in the 
config registers, and they differ also compared to the DEC docs I have.
My plan is to do "real" probing for controllers, and remove the 
config register checking. Something new will soon show up.
