    sys/i386/isa         wd.c 
    sys/kern             subr_diskmbr.c 
  Log:
  Don't permit generation of non-physical disk addresses.
  
  subr_diskmbr.c:
  Don't "helpfully" enlarge our idea of the disk size to cover all the
  primary slices.  Instead, truncate or discard slices that don't seem
  to be on the disk.  The enlargement was a hack for disks that don't
  report their size (e.g., MFM disks).  It is just wrong in general.
  
  wd.c:
  In CHS mode, limit the disk size so that cylinder numbers >= 65536
  cannot occur.  This normally only affects disks larger than 33.8GB.
  CHS mode accesses to addresses above the limit are now properly broken
  (an error is returned instead of garbage for reads and disk corruption
  for writes).
