Coreboot-Based Dasharo Updated For MSI Z690-A With Raptor Lake S, MSI FLASHBIOS

The firmware folks at 3mdeb have released Dasharo 1.1.2 for the MSI PRO Z690-A motherboard. In case you missed it, last year 3mdeb ported Coreboot/Dasharo to select MSI desktop motherboards that are readily available in retail channels and supporting the latest Intel processors. This started with the MSI PRO Z690-A and since extended to the Z790 series. 3mdeb has released an updated Dasharo build with some new features for replacing the proprietary BIOS on these motherboards.

Dasharo/Coreboot for the supported MSI motherboards is quite a treat compared to Coreboot mostly being found on select Linux laptops, Google Chromebooks, and then for desktop hardware often relegated to generations-old platforms. Thanks to 3mdeb, one can go buy one of these MSI motherboards and easily flash and begin running with this free and largely open-source alternative to the proprietary BIOS/firmware shipped by MSI. It's a real treat for supporting latest-generation processors, the newest desktop features, and motherboards that are readily available in retail channels without a significant cost premium compared to other choices like say the POWER-based Raptor systems.

With Dasharo 1.1.2 for the MSI PRO Z690-A they have extended their firmware solution with MSI FlashBIOS recovery support, Raptor Lake S CPU support on the Z690 board, support for logo customization of the initial firmware screen, a Firmware Update Mode feature, and a number of bugs fixed. With the MSI FlashBIOS Recovery support, there is greater reassurance against potentially bricking your motherboard in the event the firmware flashing goes awry.
