Hello,
I was able to successfully reflash the BIOS of a P5K-VM motherboard with flashrom-0.9.4. It recognized 2 different flash chips (AT25DF081A and AT26DF081A) at the same address. I selected the first of the two chipsets.
I wasn't sure if flashrom did support my hardware. According to your wiki it wasn't tested before. Luckily, it did its job without a hiccup. Thank you a lot for providing such a useful tool, I hope I can help you by sending you this new data.
Hello Grischa,
Thanks for your report! I have marked the mainboard as supported and will commit that later together with other small changes.

the chips are not found "at the same address", but report the same ID when queried. atmel did no give them distinct IDs so we can not distinguish them on our own, hence your help was required*, sorry.
* i have not looked at the respective datesheets. it is possible that the other definition would work equally.
