[...] I have seen Paradox 3.0 refuse to run using certain EMS emulators on 386 systems. For instance, I usually run under DOS 4.01 with the MS-provided EMM386.SYS driver installed, and Paradox likes that just fine. However, my new machine here at home came with a disk of utilities supplied by the motherboard vendor, and one of the programs on this disk was an 386 EMS emulator. I tried using it, and Paradox would crash the system with an error message along the lines of (don't remember it exactly) "Expanded Memory Error B505". So I tried running Paradox with the command line argument "-emK 0", which tells Paradox to use NO expanded memory. That worked. Then I tried putting the EMM386.SYS driver on that system, and not using the -emK argument, and Paradox was happy with that too. The only EMS-using programs I have are Paradox, WordPerfect 5.1, and Turbo C 2.0. Of those, only Paradox had trouble with the other EMS emulator.
