HELP - Informix-SE for DOS under OS/2 Warp

Does anyone have experience getting Informix-SE v4.10 for DOS to work under OS/2 Warp? When I try to start the engine from a DOS prompt, I get the message: DOS/16M error: [30] program must be built -AUTO for DPMI The person I spoke to at Informix said that it is possible, as long as I load PSTARTSQ into low memory. I've monkeyed with all the DOS and DPMI settings and still get the same message. Any info would be appreciated.
