   Thanx for the complete run down.   Now when someone says "you can't use
interrupt 2"  I will know what is really going on.  Now that all this
is over with, I managed to track down the machine on which I had set up the 
ethernet as int 2 and found that I had told config that it was int 9.  So 
at some point I had tried int 9 and it worked and I promptly forgot about it.
