It is extremely likely that the problem you are encountering is due to
an additional flash protection mechanism of your board that prevents
erasing and modifying the flash chip contents. Asus employs such a
mechanism on most of their boards, and for your board the mechanism has
not yet been analyzed and a special "board enable" code added to
flashrom.

To make completely sure the BIOS has not been tampered with, you might
want to verify the current contents of your BIOS against the a backup
(if you did one before attempting to flash). You can do that using the
"-v" option of flashrom. It compares the current flash contents with the
contents of a file given at the command line.
