  Interrupt:   13h     Function:   0Dh
 
  Title:       Reset Fixed Disk System
 
  Description:                                          [PC] [AT] [PS/2]
 
     Resets the fixed disk controller, recalibrates attached drives
     (moves the read/write arm to cylinder 0), and prepares for
     subsequent disk I/O. This function is supported on fixed disks
     only. It differs from Int 13h Function 00h in that the floppy disk
     controller is not reset.
