I have ported fasm to Dex4u OS, if you want to test it, a selfextrating exe to put it and the OS on a floppy is here: http://www.dex4u.com/Dex4uFasm.zip
Remember it only beta and the source will be released as soon as i got approval .

NOTE: Do not ask about emulators i do not use them.

nice now you can do programme development in the OS itself

i think that is first thing to do after getting OS to the point it is possible...


edit: if someone else than dex4u could advice me, how can i run this with emu and what emu should i use? (i dont have floppydrive which is shame and lame excuse for not testing out OS's distributed in floppy-fitting-size)

asuming you're using windows, you'll need this http://www.h7.dion.ne.jp/~qemu-win/ and the file attached

extract the file to the directory where qemu is installed and execute the .bat file.

that's all!

EDIT: you can also put this os on a cd you know

CD may be a problem, has it write output to floppy, i will add a option to load output to memory.
I will post when done.

The Source code to Dex4u OS FASM port, has been released and is available here: http://www.dex4u.com/download.htm
May help others, port fasm to there OS.
Regards Dex.

PS: Thanks Tomasz Grysztar, for a great assembler .
