INT 21 - CD-ROM device driver - IOCTL INPUT
        AX = 4402h
        BX = file handle referencing character device for CD-ROM driver
        CX = number of bytes to read
        DS:DX -> control block (see below)
Return: CF clear if successful
            AX = number of bytes actually read
        CF set on error
            AX = error code (01h,05h,06h,0Dh) (see AH=59h)
Note:   the data returned depends on the first byte of the control block; the
          remainder of the control block is filled by the driver
