I can't get this to work:

Code:
times 512-($-$$) db 0
dw 0xAA55    


it gives me an error that goes like "Invalid Value"

And are there any sites dedicated to OS development in fasm? Or any other sites you could recommend for beginners?

Yeah, but the problem is that it's NASM only, and I think he wants the fasm version of the code Smile
But yeah, I noticed the 512 in the code Wink

The Dex4u's code is correct for fasm. The original one is not, because it uses $$ symbol. However I've decided to implement the $$ in future releases of fasm. You can get the 1.59 pre-release from the Download section and it has it already implemented (and documented in the new section "Addressing spaces" in documentation).
