These two pictures explain the idea behind secure firmware updating very clearly: This updating protections is active even if you don't enable secure boot. Since secure boot looses its purpose if firmware updates aren't verified and protected as well, the latest UEFI implementations come with a secure firmware upgrading procedure which makes sure that only properly signed and unmodified images can be flashed. With the appearance of Windows 8 and Microsoft's requirement for OEMs to support 'secure boot' in order to get the Win8 certificate for their machines, a lot of the most recent systems (notebooks and desktops) use now firmware which is digitally signed. If you know other ways to get around the current firmware updating restrictions (per software), please let me know. I hope this will be useful to some of you. Since some of the more recent bios mods require the tool described below in order to allow flashing, I decided to share some information about it.Īlso I really don't like how users get locked out of their own hardware, this is a way to circumvent a couple of the more recent restrictions of certain systems. This article is meant as an explanation for interested / advanced users. * It still won't work for all of them, but for some it does.

* This is only for systems with Intel chipsets.
