Well, I guess that explains why ems40.sys doesn't work with my windows/286.

The system won't boot with himem.sys smartdrv.sys and ems40.sys loaded.

What it doesn't explain is why paradox 3.0 won't load with ems40.sys
loaded. I have a 10Mhz 286 with 1 meg on the Motherboard and 2 3Megs add
in cards as exTENded memory. Can't set them for expanded. Anyway Paradox
3.0 just freezes the whole system (have to hard reset) if ems40.sys id
loaded. Doesn't even show the opening screen.

Any help would be aprreciated.
