Int 2F Fn AC01  - Qrip/tsr - Change Internal Flags                         [V]

   AX = AC01h
   DI = 1092h
   BX = flags to be turned on (see #2651)
   CX = flags to be turned off (see #2651)

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 = new flags (see #2651)
