Initializing internal programmer No coreboot table found. DMI string system-manufacturer: "Elitegroup Co.

Hi Stefan Patch added and seems to work fine.I will not claim that I understand why the updated BIOS don't show any signs of being updated. Clearly something was changes in the Flash as the readout are different. But I will leave it at that for now.
Thank you for all your time and effort in this project. #flashrom -p internal -r readrom2.rom <output> flashrom v0.9.6.1-r1627 on Linux 3.2.0-34-generic-pae (i686) flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop... OK. Found chipset "SiS 650". This chipset is marked as untested. If you are using an up-to-date versionof flashrom *and* were (not) able to successfully update your firmware with it, then please email a report to [email protected] including a verbose (-V) log.
Thank you! Enabling flash write... OK.Found Winbond flash chip "W49F002U/N" (256 kB, Parallel) at physical address 0xfffc0000.
