[flashrom] Write on an ASUS M4A78-EM

[Jani Uusitalo]

Hi list.

Just flashed my ASUS M4A78-EM using flashrom (Ubuntu packed version
0.9.1+r946-1ubuntu1, with latest rev. 2101 ROM from ASUS), and
everything went fine. Just thought I'd send this note since the
motherboard isn't listed in the wiki yet. Reading the old image from
chip also worked fine.
