Re: please help this newbie running asm programs!!!

Hi,

I don't understand your point. It's quite useless what you're trying to do.
Why not run your DOS based program with DOSEMU? And what's the relation
between DOS programs and ELKS? I can't get your point sorry ...

OK.
Try it with NASM, beleive me, it's much simplier for you :)

->

[BITS 16]
org 100h
mov ah,9
mov dx,hello
int 21h
int 20h
hello DB 'Hello',13,10,'$'

This will work when assembled with NASM, and run under DOS as a simple .COM
file.

Yes, linker expect a starting symbol, it's quite normal otherwise which opcode
will be the first to execute? :)))
