Int 21 Fn 4408  - Dos 3.0+ - Ioctl - Check If Block Device Removable       [D]

   AX = 4408h
   BL = drive number (00h = default, 01h = A:, etc)

Return: CF clear if successful
       AX = media type (0000h removable, 0001h fixed)
   CF set on error
       AX = error code (01h,0Fh) (see #1366 at AH=59h/BX=0000h)

Notes: in addition to the normal operation, if Stacker is installed, this
     call also sets the volume number at offset 58h in the Stacker
     device driver (except under DR DOS 3.41-5.0, which do not pass
     through this call to the driver; use AX=440Eh instead)
     (see AX=4404h"Stacker",AX=440Eh,INT 25/AX=CDCDh)
   this function was not supported by Digital Research's DOS-Plus
