  Modified files:
    sys/isa              fd.c fdreg.h 
  Log:
  Change the PIO loops from a hard counter into a loop that calls DELAY()
  in each cycle, with a tunable max cycle count defined in fdreg.h.
  
  This is said to fix the problem on some Compaq hardware (and perhaps
  on other machines using the Natsemi PC87317 chip) where the fdc(4)
  driver failed to operate at all.
