I can see that the mod has a deferent checksum, but I dont know which byte is used to checnge the checksum of the bios. Have you tryed to flash the mod with an biostar DOS flash utility ? If anyone alse knows how to change the bios checksum or how to flash, it will be apritiated...
Gigabyte GA-MA790FX-DS5 F6 @ Bonalizaa Petar and Shay_g both modded the above BIOS on 10 July 2008. On 11 July 2008 I replied with the following post: The BIOS may or may not work, I have not been able to get the modded BIOS to stick therefore I cannot say if Vista will be activated or not. If you can find a way to make the BIOS stick and not get rejected on reboot then please let us know.
