- There's a *free* program called QTEST which is available from Quarterdeck
- to test your system to see if QRAM will do you any good. You might try
- finding a copy.
-
- A *lot* of EMS board claim "LIM 4.0" compatiblity by having a driver
- that supports the 4.0 *calls*. But if the *hardware is only 3.2 compatible,
- you can only establish the single 64k page frame and not map to locations
- outside it. Yours is likely such a board.
