Int 13 Fn 13  - Syquest - Read Drive Paramaters (for Dos 5+)               [d]

   AH = 13h
   DL = drive ID (bit 7 set for hard disks)

Return: CF set on error
       AH = status (07h) (see #0166 at AH=01h)
   CF clear if successful
       AH = 00h
       BL = drive type (AT/PS2 floppies only) (see #0174)
       CH = low eight bits of maximum cylinder number
       CL = maximum sector number (bits 5-0)
        high two bits of maximum cylinder number (bits 7-6)
       DH = maximum head number
       DL = number of drives
       ES:DI -> drive parameter table (floppies only)

Notes: the return values are identical to the standard INT 13/AH=08h, but the
     number of drives is not limited to 2, so
   scanning all possible drive numbers with the Read DASD Type call
     (AH=15h) should generally be preferred to determine the number of
     drives attached to the system.
