NovaCustom V54xTNx 14th Gen Dasharo Release Notes
Following Release Notes describe status of open-source firmware development for NovaCustom V54xTNx 14th Gen
For details about our release process please read Dasharo Standard Release Process.
Note
btg_prod binaries are signed with production Intel Boot Guard keys,
and are safe to install on platforms with Boot Guard disabled as well as
those that have Boot Guard enabled, and both on fused and unfused platforms.
Flashing these binaries enables Boot Guard but does not perform platform fusing, which means that the Boot Guard key configuration is mutable as long as the platform is not fused. Check the TrustRoot documentation for more information.
