INT 21 - SMARTDRV.SYS v3.x only - IOCTL - GET CACHE STATUS

	AX = 4402h
	BX = file handle for device "SMARTAAR"
	CX = number of bytes to read (min 28h)
	DS:DX -> buffer for status record (see #01447)
Return: CF clear if successful
	    AX = number of bytes actually read
	CF set on error
	    AX = error code (01h,05h,06h,0Dh) (see #01680 at AH=59h/BX=0000h)
Note:	NCache2 (from the Norton Utilities v8.0) attempts to support this
	  interface, but does not do so correctly, often hanging the system;
	  one should use the SmartDrive v4.x or NCache private interfaces
	  (see INT 2F/AX=4A10h/BX=0000h,INT 2F/AX=FE00h/DI=4E55h)
