Hi,

Here is some more info regarding my last email. Writing the new flash 
image failed. Before that I read the old and verified it with flashrom.

$ sudo flashrom -v bios_old_2013-05-26.bin
flashrom v0.9.5.2-r1517 on Linux 3.2.0-44-generic (x86_64), built with 
libpci 3.1.8, GCC 4.6.3, little endian
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Found chipset "NVIDIA MCP67". Enabling flash write... This chipset is 
not really supported yet. Guesswork...
Please send the output of "flashrom -V" to flashrom at flashrom.org with
your board name: flashrom -V as the subject to help us finish support 
for your
chipset. Thanks.
OK.
Found PMC flash chip "Pm49FL004" (512 kB, LPC, FWH) at physical address 
0xfff80000.
Flash image seems to be a legacy BIOS. Disabling coreboot-related checks.
Reading old flash chip contents... done.
Verifying flash... VERIFIED.

Uh oh. Erase/write failed. Checking if anything changed.
Good. It seems nothing was changed.
Writing to the flash chip apparently didn't do anything.
This means we have to add special support for your board, programmer or 
flash chip.
Please report this on IRC at irc.freenode.net (channel #flashrom) or
mail flashrom at flashrom.org!

You may now reboot or simply leave the machine running.
