Definitely try latest JEMM386 5.74, but honestly, I think the problem is two-fold (blindly guessing, so I could be wrong): 1). NOEMS is rarely used, and a lot of things don't handle it well. I think this means VCPI is still available as well as UMBs but not EMS. In other words, I guess? you're trying to save precious conventional memory by using JEMM386 while only using XMS (no EMS). Honestly, unless you really *need* that much conventional memory free (unlikely, as FreeDOS is pretty efficient), I wouldn't do this. Just load a XMS driver only (and not via "NOEMS"). 2). Actually, I've noticed JEMM386 will hang if you aren't careful, esp. on newer machines due to memory conflicts. In particular, your "I=TEST" parameter is pretty dangerous. I think typically it works better if you do "X=TEST I=TEST" (or maybe even not at all). Lemme search my old mails for a sec ... Apparently, BioMenace (DOS game, now freeware, see 3D Realms site) needs both EMS (hence EMM386) and XMS and (at least for my other, older P4) "X=TEST I=TEST NORAM". Normal JEMM386 loading just hung, and anything else didn't give it enough EMS to load to E1L3 without crashing the program due to insufficient memory. I blame ACPI, natch. P.S. Maybe I'm way off, and I know you're talking about a vaguely different problem, but just keep in mind, EMM386 can be tricky on newer hardware with weird memory configs (ACPI). That's the whole point I was trying to make, however futile it may seem. (You can also run "JEMM386 LOAD" at any time but that doesn't give you UMBs. JEMMEX doesn't let you run as pure XMS only.) ------------------------------------------------------------------------------ Achieve unprecedented app performance and reliability What every C/C++ and Fortran developer should know.
