Int 4D Fn 07  - Ti Professional Pc - Disk - Get Retry Status Of Last Oper  [B]

   AH = 07h
   DL = drive (bit 7 set for hard disk)

Return: CF clear if status unchanged
   CF set if status changed since last call
   AH = 00h
   AL = status of previous operation (see #0166 at INT 13/AH=01h)

Notes: this function is nearly the same as INT 13/AH=01h on a standard PC BIOS
   the TI's BIOS tranparently performs a number of retries; this function
     returns the error status of a failed operation even if the operation
     succeeded on a retry
