Int 2F Fn ACF0  - Qrip/tsr - Installation Check                            [V]

   AX = ACF0h
   DI = 1092h

Return: AX = 9142h if installed
       DX = DOS-takeover flag (nonzero if QRIP able to take over DOS)
       ---if DX nonzero---
       BX = QRIP version number in hex (BH = major, BL = minor)
       CX = current flags (see AX=AC01h)

Note:  if DI <> 1092h on entry, QRIP chains the call
