coreboot-15h, also known as Mike's Coreboot, is a distribution of Coreboot for the ASUS KGPE-D16, developed by mrothfuss, focused on improving reliability and hardware compatibility over upstream Coreboot 4.11 and Dasharo 0.4.0. coreboot-15h includes changes for dramatically more stable memory initialization, significantly improved HyperTransport configuration, support for hardware monitoring and fan control, and patches to the build system to allow building on current Linux distributions. It is, at the time of writing, believed to be the most stable and complete Coreboot variant available for the hardware it targets.
History
As coreboot-D16, coreboot-15h was previously provided in two versions - coreboot-4.11 and coreboot-4.15. The former was based on upstream Coreboot 4.11, while the latter is based on Dasharo's KGPE-D16 port (an earlier out-of-tree effort to reintroduce KGPE-D16 support in Coreboot, ultimately not upstreamed), which is itself effectively a fork of Coreboot around the 4.15 release. Despite being based on an older version of Coreboot, the coreboot-4.11 version was more actively developed, was in much more widespread use, has seen significantly more testing, and was generally considered more stable and performant. The older coreboot-4.15 version can be found in the old GitHub repo.
coreboot-D16 also includes a modified version of fand.cpp, for use with OpenBMC, providing improved BMC-based fan control for KGPE-D16 users running OpenBMC. At present, you will need to manually replace this file in your OpenBMC source with the coreboot-D16 version before building OpenBMC in order to use it.
Building
Example for KGPE-D16, with SeaBIOS as a payload and including the AST2050 VGABIOS.
make crossgcc-i386 CPUS=$(nproc) git submodule update --init --checkout 3rdparty/blobs cp configs/config.asus_kgpe-d16_seabios_vgabios .config make
