INT 67 - Q87 v4+ - INSTALLATION CHECK AX = 4321h EAX = 87654321h (entire EAX value required) Return: EAX = 12345678h if Q87 is installed Note: this call requires that VCPI services be available; if they are not, this call will not be recognized BUG: v4.00-v4.03 will hang on most machines when run under bare DOS with no memory manager, because neither Q87 nor UNLOAD87 checks whether there is a valid INT 67 handler before performing an installation check via INT 67 SeeAlso: AX=2833h,INT 21/AX=4321h
