The purpose of this post is to help.
Thanks to this forum, I changed the bios for B85-G43 GAMING with Success.
In the archive you have the last bios ‘E7816IMS.C80_ORIGINAL’ and the modified one 'E7816IMS.C80_MOD’
Put on a stick E7816IMS.C80_MOD, restart PC, enter Bios and update.
Please DO NOT use another method, I did so and I did NOT have any problems.
ATTENTION, if something does NOT go well I am NOT responsible, it is your choice.
Good luck and thanks to the Win-Raid forum.
