but I was never able to understand what actually is DOS?
Is it an OS just like Windows and the OS’es based on Linux kernel?
or something else?
Please explain in detail and in your own words.
How can it run on the current windows models?

I’m trying to code an "Hello World" program in x86 assembler using GNU assembler. I started with a simple .COM file that has no headers, but just a starting location of 100h. So here is the code:

[code]
. = {content}x100

leal ($MSG), %edx
movl {content}x900, %eax
int {content}x21
movl {content}x4C00, %edx
int {content}x21

MSG: .asciz "Hello, World!\n"
[/code]

well the directive . = {content}x100 give me the warning "undefined symbol {content}x100, zero assumed" and so, ofc, my code wont work

…why?
