That sounds like a DOS error.. you sure your doing "fasm file.asm"?.. sounds like your trying to run the source file if anything Smile

yup,
1. add "org 100h" and the beginning and "int 20h" at the end Smile
2. in command line write "fasm file.asm file.com'
3. run "file.com"

i quess it's not time for you to write OS yet. but of course, you can't use int 20h outside DOS. But your problem is problem of logic - what should int 20h do in your OS. int 20h is exit to parent program, so it has no meaning in OS.
