I have a question about disassembled code. I have a very simple assembly code that prints "Hello world" to screen. When I disassembled it by using nasm(ndisasm), I got a text file. After that I opened it and started to analyze it. However, in a section that comes after " int 0x80" there are a lot of "add [bx+si],al" statement. What does it means? Can you explain me?
