Hi all, i've a problem.
My computer is running w7 64 bit and i tried to use fasm to assemly some files; but when i type "fasm file.txt file.com" (ok all right) and then "file.com", it says me that it needs a 64bit fasm's version.

I need to run my code, and when i compile it's ok, but i need to see the output and now i can't beacuse of an error(it needs 64bit fasm's version).

please help me

(i supposed that i need to use fasmw but it's the same..)

That was an problem I never solved.

But, may I suggest to you DosBox| http://www.dosbox.com/

I think Win7 does not support 16 bit anymore (IDK, I never tried it but that is what I hear from many people)

Windows 7 64-bit(or any 64-bit Windows) no longer supports 16-bit backwards compatibility. I recommend what typedef said, download DOSBox. It may not support some DOS functions though. The best solution for this probably is to download an old version of MS-DOS (say 6.22 or 5), install it in VirtualBox, and then place your programs on a virtual floppy.

Do not forget reading "DOSBox x.xx Manual.txt" first.
E.g. below is what i got from it:

%UserProfile%\Local Settings\Application Data\DOSBox\dosbox-0.74.conf:

hi,

i ran into the same issue.

what does that mean from assembly programming point of view? can't we program assembly under windows 7? can't we have access to interrupts?

if yes, then where should beginners start?

thanks

As far as i know XP was the last version to support interrupts.
No more BIOS or DOS interrupt emulation for anything newer.
So DOSBox on Vista or 7 is the logical choice.
But now those old DOS games will be slow.
A good reason to keep an old box with XP or lesser on it.

No, 32 bit versions of Vista and 7 have it. It's just the 64 bit versions. And also, DOSBox will run the same speed on any OS (depending on memory of course).

I don't think XP supports DOS mode. If rugxulo is still here he can explain thoroughly.

From what I heard Win 98SE was the last Win built on DOS and you could still run true DOS apps and use BIOS calls. The problem will be getting chipset drivers for newish mobo etc.

OK, here it is

I hope I answered your question/s...
