How can I use tasm to create a simple OS?
Please tell the whole procedure for creating a binary file and if possible with a small example. I looked into the wiki but found nothing about tasm.

What version, and what platform, 16, 32-bit or mixed?

Also, why not use NASM or YASM, since they have a more brief and simpler syntax (my point of view)?

See here: http://www.beroset.com/loader.html
Also you can use "bootprog" to to load a com or mz exe file coded with tasm in the normal way.

V2_os was made originally with tasm.
