I got it to work when booting from floppy! All I had to do was copy the CWSDPMI.EXE to the same folder as my program. Easy as that :-) http://www.delorie.com/djgpp/dl/ofc/simtel/v2misc/csdpmi5b.zip/ I know I'm beating this into the ground here, but just for completeness .... For the record, like I ...

Windows ME isn't quite the same as either Windows 98 or 95 in that regard. Those both have the option of restarting the computer in DOS mode, and therefore the possibility of adjusting the Autoexec.bat and the path. Not so with Windows ME. The only way to get to DOS is booting from floppy disk, and...

IIRC in the go32 distribution (the extender from DJGPP), there is a cwsdpmi.exe which is a minimal dpmi provider for plain dos. You might also need to load himem.sys, and maybe you also need go32.exe IIRC win9x doses load himem.sys by default, so it might be a matter of putting cwsdpmi.exe in your ...

I have a question about DPMI (DOS Protected Mode Interface) and the .exe files produced by FreeBASIC. My question is, when is it necessary to use DPMI, and what particular parameters are needed to run my programs with it? I ask because my DOS programs made with Freebasic all run fine under Windows ...

I know this is late, but I never knew anything (until recently, and only barely!): One guy on freedos-devel recently experimented with this a little bit. The thread (mentioned) explains some of it. However, he wasn't 100% successful (at least, not on Intel multi-core machines) because of the way thi...

FB-dos is based on DJGPP, which apparently doesn't have the Unix sockets API out of the box. At least there's no socket.h. If the libc.a & co don't have these functions then with FB you'd only get linker errors anyways. http://www.delorie.com/djgpp/v2faq/faq22_4.html Network support libraries: ...

Not sure about how complete it is. I don't use SSH much (and not at all on DOS):

I'm pretty sure there was another DOS port (8086?) somewhere, but I forget where it is.

Yes, you can optionally target the Win32 API with a compiler, produce a PE/COFF .EXE, and run that (with restrictions) under HX. Sometimes you have to set certain options like "set HDPMI=32" and/or "set DPMILDR=32" (or "set DPMILDR=128" or "set DPMILDR=136", ...

BTW, I'm not unsympathetic to the idea of a DOS VM. I have often thought that, with DOSBox, that DOS is still a valid target a la Java/JVM (even if weaker, obviously). Of course, that's not a popular opinion, so I don't expect anyone to sympathize (and know for a fact that most don't). Just so you k...

wah wah wah I can't speak for anyone else. I'm not ragging on Android at all, it works fairly well. But ... the overall ecosystem of computing is very throwaway these days. My machine is already (!) unsupported by Lenovo, using "old" kernel 2.6.36, probably won't get more updates, has som...

Maybe it will work to have fbc set the DJGPP environment variable in that case. You normally also need DJGPP.ENV from DJDEV*.ZIP. That's what the %DJGPP% env. var. points to, anyways. Without that, it doesn't know where to find the various GCC pieces that aren't in the %PATH%. (from memory, here's ...

All Win32 (PE/COFF) binaries these days are "relocs stripped". The relocations (not counting .DLLs) were only strictly needed for old Win32s (atop Win 3.1). Yes, you can optionally target the Win32 API with a compiler, produce a PE/COFF .EXE, and run that (with restrictions) under HX. &quo...

Although personally I find it quite strange that instructions like REP LODSD/STOSD/MOVSD would not have been optimized to run as fast as possible by the chip designers, but instead there is a gain to be had with silly unrolled loops. "REP LODSx" is not very widely used, AFAIK. But "R...

I ran the original C code by compiling the file with dev C. Had to change random() to rand(). That's mentioned on the original download page: "In addition, random() was changed to rand(), because the former does not seem to be universal (gcc recognizes both)." Even DJGPP's libc has "...

I have not used FB a lot (and barely know anything in general anyways), hence my slow reply here: int 21h, 6601h is only for "system" code page (used by CHCP), not the "display"-ed one. (They don't have to match, although ideally they maybe would, if everything were fully support...
