    _______________________________________________________

Details:

I found "chainloader +N“ or ”chainloader file“ only loads 512 bytes
maximum to 0:0x7c00.

It should be better that 
"chainloader +N" loads N sectors

and

"chainloader file" loads the whole file.


I made a patch file(for chainloading file), and it worked.
though I don't know if it has side-effects.
