A summary of the upcoming UEFI capsule updates, exploring areas that were in need of improvement and what has actually been done. The developments affect general usage and documentation, provide strong security guarantees, and enhance feedback during firmware updates. Additionally, a related subject of fwupd as a capsule delivery mechanism on FreeBSD, Qubes OS and Windows is also covered.

3mdeb’s latest Dasharo builds finally let you touch CPU and memory voltages from an open-source BIOS. The release notes are refreshingly blunt about what happens next.

The latest Dasharo firmware release for MSI PRO Z690-A (v1.1.7) and MSI PRO Z790-P (v0.9.5) is here. This release brings preliminary SMI Transfer Monitor support, a new Platform Setup Menu with experimental CPU overclocking options, XMP improvements, and many other fixes and enhancements.

A look at DRTM on ARM: where it stands compared to Intel TXT/AMD SKINIT and what will it take to run TrenchBoot on AArch64. How can TrenchBoot support both x86 and ARM architectures at the same time.

"Long story short, the Dasharo performance led to effectively the same performance as the default proprietary BIOS performance overall. No overall loss in performance in going for the AMD openSIL / open-source option."

This report details a release engineering incident where a Dasharo firmware update successfully performed End-of-Manufacturing (EOM) fusing on NovaCustom laptops but utilized an ephemeral testing key instead of the persistent production key. We provide a technical analysis of the situation and outline impact for affected end users.

This is a post about the process of porting Dasharo to a modern Intel-based server platform if you would like to learn how a coreboot port is integrated into Dasharo and enhanced with its features feel free to ask any questions.

In the blog post, the author explains the effort of porting platform-specific ACPI code and shows the extent of bugfixes required to run operating systems without issues on the AMD Turin server platform, the Gigabyte MZ33-AR1.
