No idea. Look at shockprf.sys in the Windows driver:

  Shockproof Disk Driver

  Autonomic HDD Protection Manager
  IBM Hard Drive Active Protection System

You will find something like that:

  .text:0001040B                 push    3F6h
  .text:00010410                 call    ds:WRITE_PORT_UCHAR
  ...
  .text:00014661                 push    7
  .text:00014663                 push    2Eh
  .text:00014665                 call    esi ; WRITE_PORT_UCHAR
  ...
  .text:00014672                 push    7
  .text:00014674                 push    2Fh
  .text:00014676                 call    esi ; WRITE_PORT_UCHAR

  .text:00014680                 call    esi ; WRITE_PORT_UCHAR
  ...
  .text:0001482E                 push    1F0h
  .text:00014833                 call    ds:READ_PORT_USHORT
