Having no luck with data NASM

问题

section .data

map db 1

section .text

start:
cmp byte [map], 1
je exit
jmp start

exit:
ret

I'm having no luck reading data. What I mean is that I assemble to the binary dos COM format and when I start it it just freezes. Can someone tell me what i'm doing wrong?

回答1:

DOS com files are expected to be loaded at address 0x100. You should include line org 0x100 at the start of your code.
