QUERY GENERIC IOCTL CAPABILITY (DRIVE)

AX = 4411h
BL = drive number
CH = category code (see #01558)
CL = function code (see #01559)

  CF clear if successful
    AX = 0000h	specified IOCTL function is supported
CF set on error
    AL = 01h	IOCTL capability not available

a program which wishes to use Generic IOCTL calls beyond those in the

  standard DOS 3.2 set may use this call first to see whether a
  particular call is supported
