Size should be in hex (so 60000 instead of 393216). The first 64 kb _will_ be all zero if a VGA graphics page is not in use.

Thanks, I got it right now...
BTW, how do you get the ASCII representation of the byte code next to the binary code? like debug in DOS

memdump should already do that (memdumpbin outputs the pure binary code without the columnized ASCII).

Right, my memory was off there I guess. Just do a memdumpbin and load the result in your favorite hex editor (more useful than having it in the .txt, anyway).
