Yeah, gotta love problems like this. You'll have to take away and add things one by one until you can deduce what the real problem is. > NOTE: with no MS Client and without this mem optimalization it run smoothly. > I am out of ideas what else to do. > Maybe someone of you looking at my fdconfig.sys and autoexec.bat can give > some hints ? Only blind guesses since most of us don't have access to the files (and don't want them if it's illegal to copy them, most likely, please don't send them if so). > It helped me a lot parameter for jemmex.exe: I= > What I understand it reserve some areas in upper memory and in this way > extends conventional memory (?) > Not much understanding of that though :/ > I use config option 1. > It might be important that (at least for tests) I use FreeDOS inside > VirtualBox as a guest OS. It could be VBox incompatibilities. There are various issues with it as it's a lot of work to support everything. Are you running latest version (and if not, why not)? Is VT-X enabled? Is VT-X disabled? Try toggling that and trying again. (Some things work without it, some only work with it. And even that depends on what your cpu supports.) > fdconfig.sys: > https://dl.dropboxusercontent.com/u/3403127/dosbox/fdconfig.sys > > autoexec.bat: > https://dl.dropboxusercontent.com/u/3403127/dosbox/autoexec.bat Just a quick look and some comments: a). Why "FILES=20"? Isn't that kinda low? (Or are you trying to save RAM here?) b). Does this particular app need EMS or (apparently) are you just trying to save conventional RAM? If you can get enough free (which I guess you're basically saying you can't otherwise) without it, then don't load EMM386 at all. c). If you must (or want) EMM386, I would suggest "JEMM386 X=TEST I=TEST". If not direly needed, don't use "NOEMS" as that can sometimes confuse some programs. Similarly with manual "I=" or "X=", don't use those unless you're really really sure there's no conflicts. "NOVME NOINVLPG" is only (IIRC) for buggy emulators like MS VCP or perhaps if you're running on a real 386 that lacks those (586, 486) extensions. I wouldn't disable them unless sure it was necessary. d). Hmmm, you are using JEMMEX in config 1, so perhaps it would work better to load XMS and EMM386 separately, e.g. XMGR + JEMM386. e). I can't remember exactly, but there was some obscure bug / quirk with SHELLHIGH (as Eric mentions) with COMMAND.COM, so I'd avoid that entirely (as mentioned, using such a thing doesn't save much). You could try using 0.82 instead of 0.84, but I don't know if that would help here. 4DOS should work okay too, but in some rare cases it has minor (timing) issues too. Honestly, I don't know. Maybe it's some low-level quirk that only MS-DOS supports (due to MS shared development). I know Eric mentions xHarbour, but I don't think they actively support DOS anymore, so unless ye olde 1.01 (IIRC) works and you can rebuild, that may not be reliable. No idea about DOSEMU or DOSBox and network drives, maybe it works. Is your Clipper/dBase app using any kind of extender or pmode? Or is it 100% real mode? I've noticed that a lot of extended DOS apps have various bugs. Perhaps you could try loading HDPMI16 and/or HDPMI32 first, and see if that helps. Other than that, dunno. The only real way to know is to run through a debugger (Bochs? DOSBox?) to see where it hangs / crashes. Do you know what requirements the .EXE needs? Was it ever publicly specified? For all we know, it could be doing something dumb like looking for specific versions of certain APIs or whatnot and accidentally getting confused. ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
