Hi,
All I would like to develop is a 32 bit operating system.
So I have started with NASM x86 32-bit programming.
But when is it that i require 16-bit assembly programs while developing an operating system.
 
Could you please suggest?

The question makes little to know sense. You need to learn a bit on how OS work in principle, and, I suspect, how programming and computer work. The life cycle of OS development it not that simple...

That's a daunting task!

I would have first studied some books about operative systems.

I wouldn't bother about.

This question is so irrelevant compared to the task at hand. BTW: why would you write an OS in assembly? This was given up in the senventies of the last century, I.e. C was invented to re-write UNIX since without it the work results would not have scaled...
 
Almost everything you can achieve by assembler can be achieved by decent C cross-compiler - some rare exceptions apply.
Everything you can achieve by C can be achieved by a decend C++ cross-compiler - probably no exceptions apply. Wink | ;-)
 
Is there some I-write-my-own-OS fever breakout? E.g. see also a resent similar request[^]. Wink | ;-)
 
Expectations on "OS" may vary, though.
 
Cheers
Andi
