AMD's open-source openSIL firmware is being ported to Zen 5 motherboard early — replacement for AGESA shows up ahead of Zen 6

AMD is transitioning from its AGESA microcode to the open-source openSIL firmware, starting with Zen 6, but early adoption is underway for Zen 5 motherboards like the MSI B850-P Pro. The openSIL firmware, developed by 3mbdeb, offers improved security and transparency compared to AGESA. While openSIL is not yet production-ready, it provides enthusiasts and developers a chance to explore its capabilities and design. This shift signifies AMD's commitment to open-source firmware development and enhanced security measures for future CPUs.
